Which of the following is a valid relational operator in C?

Explanation:

Relational operators are used in C programming to compare two values or expressions. These operators evaluate the relationship between operands and return either true (non-zero value) or false (zero value) depending on the condition being tested.

Purpose: Relational operators are commonly used in conditional statements, loops, and decision-making constructs to control the flow of execution based on specific conditions.

List of Relational Operators in C:

• ==: Checks if two values are equal.
• !=: Checks if two values are not equal.
• <: Checks if the left operand is less than the right operand.
• >: Checks if the left operand is greater than the right operand.
• <=: Checks if the left operand is less than or equal to the right operand.
• >=: Checks if the left operand is greater than or equal to the right operand.

Example:

#include 

int main() {
    int a = 5, b = 10;

    if (a != b) {
        printf("a is not equal to b\\n");
    } else {
        printf("a is equal to b\\n");
    }

    return 0;
}

Output:

a is not equal to b

The != operator compares the values of a and b. Since 5 is not equal to 10, the condition evaluates to true, and the message "a is not equal to b" is printed*33333333333333
