8.2 Logical Operators and Comparisons

The most common thing to use inside the logical operators is a comparison. Conveniently, ‘ && ’ and ‘ || ’ have lower precedence than comparison operators and arithmetic operators, so we can write expressions like this without parentheses and get the nesting that is natural: two comparison operations that must both be true.

This example also shows how it is useful that ‘ && ’ guarantees to skip the right operand if the left one turns out false. Because of that, this code never tries to divide by zero.

This is equivalent:

A truth value is simply a number, so using r as a truth value tests whether it is nonzero. But r ’s meaning as en expression is not a truth value—it is a number to divide by. So it is better style to write the explicit != 0 .

Here’s another equivalent way to write it:

This illustrates the unary ‘ ! ’ operator, and the need to write parentheses around its operand.

Assignment Operators in C

In C language, the assignment operator stores a certain value in an already declared variable. A variable in C can be assigned the value in the form of a literal, another variable, or an expression.

The value to be assigned forms the right-hand operand, whereas the variable to be assigned should be the operand to the left of the " = " symbol, which is defined as a simple assignment operator in C.

In addition, C has several augmented assignment operators.

The following table lists the assignment operators supported by the C language −

Simple Assignment Operator (=)

The = operator is one of the most frequently used operators in C. As per the ANSI C standard, all the variables must be declared in the beginning. Variable declaration after the first processing statement is not allowed.

You can declare a variable to be assigned a value later in the code, or you can initialize it at the time of declaration.

You can use a literal, another variable, or an expression in the assignment statement.

Once a variable of a certain type is declared, it cannot be assigned a value of any other type. In such a case the C compiler reports a type mismatch error.

In C, the expressions that refer to a memory location are called "lvalue" expressions. A lvalue may appear as either the left-hand or right-hand side of an assignment.

On the other hand, the term rvalue refers to a data value that is stored at some address in memory. A rvalue is an expression that cannot have a value assigned to it which means an rvalue may appear on the right-hand side but not on the left-hand side of an assignment.

Variables are lvalues and so they may appear on the left-hand side of an assignment. Numeric literals are rvalues and so they may not be assigned and cannot appear on the left-hand side. Take a look at the following valid and invalid statements −

Augmented Assignment Operators

In addition to the = operator, C allows you to combine arithmetic and bitwise operators with the = symbol to form augmented or compound assignment operator. The augmented operators offer a convenient shortcut for combining arithmetic or bitwise operation with assignment.

For example, the expression "a += b" has the same effect of performing "a + b" first and then assigning the result back to the variable "a".

Run the code and check its output −

Similarly, the expression "a <<= b" has the same effect of performing "a << b" first and then assigning the result back to the variable "a".

Here is a C program that demonstrates the use of assignment operators in C −

When you compile and execute the above program, it will produce the following result −

Conditional Operator in C ( ?: ) with Example

The conditional operator in C is similar to the if-else statement. The if-else statement takes more than one line of the statements, but the conditional operator finishes the same task in a single statement. The conditional operator in C is also called the ternary operator because it operates on three operands.

What is a Conditional Operator in C

The conditional operator is also known as a ternary operator. The conditional statements are the decision-making statements that depend upon the output of the expression. As a conditional operator works on three operands, so it is also known as the ternary operator.

The operands may be an expression, constants, or variables. It starts with a condition, hence it is called a conditional operator. Conditional operators  return one value if the condition is true and returns another value if the condition is false.

Syntax of Conditional Operator in C

or for simplicity, we write it as

The expression1 is evaluated, it is treated as a logical condition . If the result is non-zero then expression2 will be evaluated otherwise expression3 will be evaluated. The value after evaluation of expression2 or expression3 is the final result.

The conditional operator in C works similarly to the conditional control statement if-else. Hence every code written using a conditional operator can also be written using if-else. When compared with if-else, conditional operator performance is high.

Conditional Operator Example

Write a C program to find the maximum in the given two numbers using the conditional operator.

Enter two numbers: 12.5 10.5 Maximum of 12.50 and 10.50 = 12.50

First the expression, (num1 > num2) is evaluated. Here num1=12.5 and num2=10.5; so expression (num1>num2) becomes true. Hence num1 is the maximum number, and it is assigned to the variable max.

Output for another test:-

Enter two numbers: 9 20 Maximum of 9.00 and 20.00 = 20.00

Here num1=9 and num2=20; so the expression (num1>num2) becomes false. Hence num2 is the maximum number and it is assigned to the variable max.

The parentheses in the conditional operator are not necessary around the first expression of a conditional expression. The precedence of conditional operator ?: is very low. But it is advisable to use parentheses, however, it makes the condition part of the expression easier to see.

The above program using a conditional operator is similar to the below program using the if-else conditional statement.

We will see more examples Later, first, let us see some popular MCQ based on the conditional operator in C language.

More Example of Conditional Operator in C

1) Program description:- Find the number is positive or negative using the conditional operator.

Output for the different test-cases:-

Enter a number: 8 Positive.

Enter a number: -10 Negative

2) Program description:- Find the given number is odd or even using the conditional operator in C.

Enter a number: 9 Odd

Enter a number: 8 Even

3) Program description:- Program to Find the minimum of two numbers using the conditional operator.

Enter two numbers: 10 8 Minimum = 8.00

Enter two numbers: 15 12 Minimum = 12.00

4) Program description:- Write a program to enter two numbers. Make a comparison between them with the conditional operator. If the first number is greater than the second, perform a division operation otherwise multiplication operation.

Enter two number: 10 20 Result: 200.00

Enter two number: 10 5 Result: 2.00

5) Another good example of the conditional operator is,

Enter the number of items: 1 You have 1 item.

Enter the number of items: 2 You have 2 items.

More than One Conditional Operator in a Statement

We can use more than one conditional operator in a statement. But in this case, it makes harder to understand the code. Use the ternary operator only when the resulting statement is short. This will make your code concise and much more readable.

Ternary operators can be used to replace multiple lines of code to a single line of code.

The above multiple lines of code can be replaced with,

Conditional Operator in C for Three Variables

Program Description:- Find the largest among three numbers using the conditional operator .

Program to find the maximum of three numbers using conditional operators.

Enter three numbers: 10 30 12 Maximum number = 30.00

Find the output of the below code?

The output of the above program: 420

The output of the above program: 5

Choose a C conditional Operator from the list

MCQ1) Choose a C conditional operator from the list?

A) ? : B) : ? C) : < D) < :

Answer:- A) ? :

We have already seen the syntax of the conditional operator. The syntax for the conditional operator is:- expression1 ? expression2 : expression3;

Choose a Syntax for C Ternary Operator from the List

MCQ2) Choose a syntax for C ternary operator from the list?

A) condition ? expression1 : expression2 B) condition : expression1 ? expression2 C) condition ? expression1 < expression2 D) condition < expression1 ? expression2

Answer:- A) condition ? expression1 : expression2

If the condition is true, expression 1 is evaluated. If the condition is false, expression 2 is evaluated. The conditional operator is also called a ternary operator.

Q1) What is a conditional operator in C with example?

The  conditional operator in C is a conditional statement  that returns the first value if the condition is true and returns another value if the condition is false. It is similar to the if-else statement. The  if-else statement  takes more than one line of the statements, but the conditional operator finishes the same task in a single statement. 

Q2) What is conditional operator write syntax?

The syntax for the conditional operator in C is:-  expression1? expression2: expression3;  Here the expression1 is evaluated and treated as a logical condition. If the result is non-zero then expression2 will be evaluated otherwise expression3 will be evaluated. The value after evaluation of expression2 or expression3 is the final result. Or for simplicity, we can also write it like-  condition? true-statement : false-statement;

Q3) What is a conditional operator used in C?

The  conditional operator is used to check whether the given condition is true or false.  If the condition is true then perform this task else perform another task. For example-  expression1? expression2: expression3;  Here the expression1 is evaluated, it is treated as a logical condition. If the result is non-zero then expression2 will be evaluated otherwise expression3 will be evaluated.

Q4) What is the function of the conditional operator?

Conditional operators are used to evaluating a condition that’s applied to one or two boolean expressions.  The result of the evaluation is either true or false.

Q5) What is the symbol used for the conditional operator? The symbol used for the conditional operator in C is ?:

Q6) How many arguments the conditional operator takes?

The ternary operator takes  three arguments : The first is a comparison argument. The second argument is the result of a true comparison, and the third argument is the result of a false comparison.

Q7) What is the other name for the conditional operator? The other name for the conditional operator is the ternary operator.

Q8) Why conditional operator is called the ternary operator?

Since the conditional operator in C works on three operands therefore it is also called a ternary operator.  The operands may be an expression, constants, or variables.

C++ Or Equals: Understanding Assignment and Comparison

CodeLikeAGirl

Oh hey there! 👋 Alright, I’m on it like a programmer on a coding spree! Let’s get this blog post on C++ and comparison operators nailed down! 💻

Understanding Assignments in C++

So, let’s kick things off by unpacking the whole assignment dealio in C++ . You know, when you’re slinging code and you want to assign a value to a variable? That’s where the action is at! Let me break it down for you.

Basic Assignment Operation

When you’re in the coding zone and you want to give a variable a fresh new value, you use the good ol’ equals sign! It’s like saying, “Hey, buddy, from now on, you’re gonna be this awesome number or string or whatever I throw at you!”

See what I did there? I just assigned a value to those variables like a boss! 😎

Multiple Assignment in a Single Line

Now, hold onto your code editor, ’cause we’re about to jazz things up! You can actually assign multiple variables in a single line. It’s like throwing a coding party and inviting all the variables to groove together. Here’s how you do it:

Boom! Just like that, I assigned values to three variables in a single, mighty line of code. Efficiency level: expert! 🚀

Comparison Operators in C++

Alright, now let’s shimmy our way into the realm of comparison operators. These bad boys help us compare stuff in our code—like, is this number equal to that one? Is this string greater than that one? Let’s do this!

Equality and Relational Operators

First up, we’ve got the equality and relational operators. These are like the cool detectives of the coding world , comparing values and telling you what’s what.

  • The double equals sign == is like asking, “Hey, are these two buddies equal?”
  • The not equals sign != is for checking inequality, like asking, “Yo, are these pals not twins?”
  • Then, there’s < for “Is this less than that?” and > for “Is this greater than that?” Imagine them as the judges in a coding slam dunk contest!

Using Comparison Operators for Conditional Statements

Alright, now the real magic happens when you slap these comparison operators into some conditional statements . It’s like giving your code a brain, making decisions based on comparisons. Here’s a little taste of what that looks like:

See what we did there? We used the less than operator to decide whether to let someone into our virtual party. Code with a heart, right? ❤️

Overall, digging into C++ and comparison operators is like unlocking a whole new level of coding finesse! So embrace those equals signs and comparison symbols, and let your code dance like nobody’s watching. 🌟

Well, that’s a wrap, folks! We took a wild ride through C++ assignments and dazzled in the realm of comparison operators. It’s all about giving variables new vibes and making our code smart with those nifty comparisons. Until next time, keep coding like a rockstar! 🎸

Program Code – C++ Or Equals: Understanding Assignment and Comparison

Code output:, code explanation:.

Okay, let’s dissect this program like it’s a high-stakes operation, and we’re the ace surgeons – without the blood and stuff, ew.

First off, we got us a template class named ‘Box. Now, what’s neat about templates is they’re like those one-size-fits-all T-shirts, but for data types . You can slap an int in there, a float, or heck, even a double, and it’ll work without a fuss.

So, our ‘Box’ blueprint has got one job; hold onto a value. We hobble together a constructor so it can latch onto whatever value you throw its way when you create a Box object.

Now the fun begins – we’ve got overloaded operators . That’s coding lingo for making an operator do extra chores. The assignment (=) operator here snatches a new value and stuffs it into our Box’s value, neat and tidy.

Then we’ve got the double agents – the comparison operators (== and !=). If two Boxes have a stare-down, these operators will tell ya whether the Boxes are doppelgängers (equal) or strangers (not equal).

Fast forward to the main() arena. We summon two Box objects into existence, intBox1 with a 10 tucked inside, and intBox2 guarding a 20. intBox1 gets a makeover and is handed a new value of 30.

We print out these values ’cause seeing is believing, right? A quick comparison follows, and since 30 and 20 are as different as chalk and cheese, our program yells ‘False’ for equality and ‘True’ for inequality.

But wait, there’s a plot twist! intBox1 gets envious of intBox2’s value and, through the magic of assignment, copies it. Now they’re value-twins. Our program wraps it up by confirming that yes, indeed, they’re now equal.

This code’s like a well-orchestrated tech ballet showin’ off assignment and comparison in all its glory. It’s the very fabric of decision-making in programming, and gotta say, it’s pretty slick! 👩‍💻🔁🤖

And with that, I’m signin’ off. Thanks a bunch for stickin’ around – catch ya on the flip side! Keep coding and stay fabulous! 💁‍♀️✨

Assignment operators.

Assignment and compound assignment operators are binary operators that modify the variable to their left using the value to their right.

[ edit ] Simple assignment

The simple assignment operator expressions have the form

Assignment performs implicit conversion from the value of rhs to the type of lhs and then replaces the value in the object designated by lhs with the converted value of rhs .

Assignment also returns the same value as what was stored in lhs (so that expressions such as a = b = c are possible). The value category of the assignment operator is non-lvalue (so that expressions such as ( a = b ) = c are invalid).

rhs and lhs must satisfy one of the following:

  • both lhs and rhs have compatible struct or union type, or..
  • rhs must be implicitly convertible to lhs , which implies
  • both lhs and rhs have arithmetic types , in which case lhs may be volatile -qualified or atomic (since C11)
  • both lhs and rhs have pointer to compatible (ignoring qualifiers) types, or one of the pointers is a pointer to void, and the conversion would not add qualifiers to the pointed-to type. lhs may be volatile or restrict (since C99) -qualified or atomic (since C11) .
  • lhs is a (possibly qualified or atomic (since C11) ) pointer and rhs is a null pointer constant such as NULL or a nullptr_t value (since C23)

[ edit ] Notes

If rhs and lhs overlap in memory (e.g. they are members of the same union), the behavior is undefined unless the overlap is exact and the types are compatible .

Although arrays are not assignable, an array wrapped in a struct is assignable to another object of the same (or compatible) struct type.

The side effect of updating lhs is sequenced after the value computations, but not the side effects of lhs and rhs themselves and the evaluations of the operands are, as usual, unsequenced relative to each other (so the expressions such as i = ++ i ; are undefined)

Assignment strips extra range and precision from floating-point expressions (see FLT_EVAL_METHOD ).

In C++, assignment operators are lvalue expressions, not so in C.

[ edit ] Compound assignment

The compound assignment operator expressions have the form

The expression lhs @= rhs is exactly the same as lhs = lhs @ ( rhs ) , except that lhs is evaluated only once.

Introduction:

In Python, comparison and assignment operators are fundamental tools for manipulating variables and making decisions based on conditions. While both types of operators involve variables and values, they serve different purposes. In this detailed blog post, we will explore comparison and assignment operators, explain their functionalities, and highlight the key differences between them. Through well-explained examples, we will solidify our understanding of these essential operators.

Comparison operators are used to compare values and variables. They return boolean values ( True or False ) based on the comparison result. Python provides several comparison operators, including == , != , > , < , >= , and <= . Let's examine each operator with examples:

c assignment and comparison in same statement

Assignment operators are used to assign values to variables. They enable us to store and update data in variables. In Python, the most basic assignment operator is = . Let's explore some examples:

c assignment and comparison in same statement

While comparison operators are used to compare values and return boolean results, assignment operators are used to assign values to variables. The key differences between comparison and assignment operators are as follows:

Purpose: Comparison operators compare values and determine their relationship (equality, greater than, less than, etc.). Assignment operators assign values to variables.

Evaluation: Comparison operators evaluate expressions and return boolean results ( True or False ). Assignment operators simply assign values to variables without returning any specific result.

Syntax: Comparison operators use specific symbols ( == , != , > , < , >= , <= ) to compare values. Assignment operators use the = symbol to assign values.

Usage: Comparison operators are commonly used in conditional statements ( if , while , etc.) and logical operations. Assignment operators are used when storing and updating values in variables.

c assignment and comparison in same statement

Conclusion:

Comparison and assignment operators serve distinct purposes in Python. Comparison operators allow us to compare values and determine relationships, while assignment operators assign values to variables. Understanding the differences between these operators is crucial for writing effective and meaningful code that involves decision-making and data manipulation.

Comparison operators evaluate expressions and return Boolean values ( True or False ) based on the comparison result. They are commonly used in conditional statements ( if , while , etc.) and logical operations to control the flow of the program. On the other hand, assignment operators are used to assign values to variables, allowing us to store and update data within the program.

It's important to note that comparison operators can be used within assignment statements to make assignments based on certain conditions. This combines the functionality of both types of operators. Let's see an example:

c assignment and comparison in same statement

To summarize, comparison operators compare values and return Boolean results, while assignment operators assign values to variables. Comparison operators are used for decision-making and comparisons, while assignment operators are used for data storage and updates.

Understanding the difference between comparison and assignment operators is crucial for writing effective code that involves decision-making, data manipulation, and variable assignment. By utilizing these operators correctly, you can create logical and efficient programs that perform computations and make informed decisions based on the conditions at hand.

c assignment and comparison in same statement

Assignment operators are used for assigning value to a variable. The left side operand of the assignment operator is a variable and right side operand of the assignment operator is a value. The value on the right side must be of the same data-type of the variable on the left side otherwise the compiler will raise an error.

Different types of assignment operators are shown below:

1. “=”: This is the simplest assignment operator. This operator is used to assign the value on the right to the variable on the left. Example:

2. “+=” : This operator is combination of ‘+’ and ‘=’ operators. This operator first adds the current value of the variable on left to the value on the right and then assigns the result to the variable on the left. Example:

If initially value stored in a is 5. Then (a += 6) = 11.

3. “-=” This operator is combination of ‘-‘ and ‘=’ operators. This operator first subtracts the value on the right from the current value of the variable on left and then assigns the result to the variable on the left. Example:

If initially value stored in a is 8. Then (a -= 6) = 2.

4. “*=” This operator is combination of ‘*’ and ‘=’ operators. This operator first multiplies the current value of the variable on left to the value on the right and then assigns the result to the variable on the left. Example:

If initially value stored in a is 5. Then (a *= 6) = 30.

5. “/=” This operator is combination of ‘/’ and ‘=’ operators. This operator first divides the current value of the variable on left by the value on the right and then assigns the result to the variable on the left. Example:

If initially value stored in a is 6. Then (a /= 2) = 3.

Below example illustrates the various Assignment Operators:

Assignment vs. the comparison operator

A common syntax error experienced by beginner Python programmers is in using the assignment operator = instead of the equality operator == in a conditional expression:

This assignment a = 5 does not return a value, it simply assigns the integer object 5 to the variable name a , and so there is nothing corresponding to True or False that the if statement can use: hence the SyntaxError . This contrasts with the C language in which an assignment returns the value of the variable being assigned (and so the statement a = 5 evaluates to true ). This behaviour is the source of many hard-to-find bugs and security vulnerabilities and its omission from the Python language is by design.

  1. Assign and compare in a single statement in C

    so that the statement (str[i] = toupper(str[i])) != 0; both assigns a char and checks to see if it is '\0' or not. The way this works is that part of the C language specifies that assignment expressions have the value of the lefthand expressions after the assignment. For example, with ints, consider the following code snippet: int x = 5;

  2. Order of assignment and comparison in an 'if' statement

    10. §6.8.4 says that the syntax for an if selection statement is: Further in this section, it mentions that if the expression compares unequal to 0, then statement is executed. The expression must therefore be evaluated before it can be compared to 0. i = 0 is an expression which evaluates to 0.

  3. What alternatives are there for C/C++ assignment operator (=) and

    C/C++ use = for assignment and == for equality comparision. For example, a snippet in C++ can be like this: int nuclear_code; nuclear_code = 1111; // assign nuclear_code with the value 1111 if ... Assignment and comparison have different purposes, return values, and allowed syntactic locations. Therefore, they should be represented with bigger ...

  4. What is the difference between = (Assignment) and == (Equal to

    The differences can be shown in tabular form as follows: =. ==. It is an assignment operator. It is a relational or comparison operator. It is used for assigning the value to a variable. It is used for comparing two values. It returns 1 if both the values are equal otherwise returns 0. Constant term cannot be placed on left hand side.

  5. Logicals and Comparison (GNU C Language Manual)

    8.2 Logical Operators and Comparisons. The most common thing to use inside the logical operators is a comparison. Conveniently, ' && ' and ' || ' have lower precedence than comparison operators and arithmetic operators, so we can write expressions like this without parentheses and get the nesting that is natural: two comparison ...

  6. Assignment Operators in C

    Simple assignment operator. Assigns values from right side operands to left side operand. C = A + B will assign the value of A + B to C. +=. Add AND assignment operator. It adds the right operand to the left operand and assign the result to the left operand. C += A is equivalent to C = C + A. -=.

  7. Assignment (computer science)

    In this sample, the variable x is first declared as an int, and is then assigned the value of 10. Notice that the declaration and assignment occur in the same statement. In the second line, y is declared without an assignment. In the third line, x is reassigned the value of 23. Finally, y is assigned the value of 32.4. For an assignment operation, it is necessary that the value of the ...

  8. Assignment Operators in Programming

    Assignment operators are used in programming to assign values to variables. We use an assignment operator to store and update data within a program. They enable programmers to store data in variables and manipulate that data. The most common assignment operator is the equals sign (=), which assigns the value on the right side of the operator to ...

  10. Conditional Operator in C ( ?: ) with Example

    The conditional operator in C is a conditional statement that returns the first value if the condition is true and returns another value if the condition is false. It is similar to the if-else statement. The if-else statement takes more than one line of the statements, but the conditional operator finishes the same task in a single statement.

  11. for both assignment and comparison : r/ProgrammingLanguages

    This choice is not bad. Keep in mind: The = in mathematics corresponds neither to an assignment nor to a comparison in programming. The mathematical = is a symmetric operator. You can exchange the left and right operand and the meaning stays the same. In mathematics a = b. and b = a. have the same meaning. But an assignment is an asymmetric ...

  12. C++ Or Equals: Understanding Assignment and Comparison

    The assignment (=) operator here snatches a new value and stuffs it into our Box's value, neat and tidy. Then we've got the double agents - the comparison operators (== and !=). If two Boxes have a stare-down, these operators will tell ya whether the Boxes are doppelgängers (equal) or strangers (not equal).

  13. C Operator Precedence

    They are derived from the grammar. In C++, the conditional operator has the same precedence as assignment operators, and prefix ++ and -- and assignment operators don't have the restrictions about their operands. Associativity specification is redundant for unary operators and is only shown for completeness: unary prefix operators always ...

  14. Comparison Operators in Programming

    Comparison Operators in programming are used to compare values and determine their relationship, such as equality, inequality, greater than, less than, etc. They evaluate expressions and return a Boolean value (true or false) based on the comparison result, crucial for decision-making in conditional statements and loops. Table of Content.

  15. Assignment operators

    Assignment performs implicit conversion from the value of rhs to the type of lhs and then replaces the value in the object designated by lhs with the converted value of rhs . Assignment also returns the same value as what was stored in lhs (so that expressions such as a = b = c are possible). The value category of the assignment operator is non ...

  16. What are comparisons and assignments?

    Assignment operators simply assign values to variables without returning any specific result. Syntax: Comparison operators use specific symbols ( ==, !=, >, <, >=, <=) to compare values. Assignment operators use the = symbol to assign values. Usage: Comparison operators are commonly used in conditional statements ( if, while, etc.) and logical ...
