How is a condition defined in an if statement in C?

In C programming, a condition in an if statement is defined using logical operators, which evaluate to a boolean value: true or false. These logical operators include && (logical AND), || (logical OR), and ! (logical NOT). When an if statement is executed, the expression provided as the condition is evaluated, and based on whether this evaluates to true (non-zero) or false (zero), the block of code following the if statement will execute or be skipped.

For example, a typical if statement might look like this:

if (x > 10 && y < 5) {

// Code to execute if the condition is true

}

In this case, the condition checks if x is greater than 10 and y is less than 5. The combination of these comparisons using the logical operator && enables the expression to evaluate thoroughly based on the specific criteria defined by the programmer.

Understanding how conditions are structured with logical operators is fundamental to controlling the flow of a program effectively.
