If Keyword

In C programming, the 'if' keyword is used to create an if statement, which is a control flow statement that allows a block of code to be executed conditionally based on a specified condition.

Here's an example of using the 'if' keyword to create an if statement:

int x = 5;
if (x > 0) {
printf("x is positive");
}

In this example, the 'if' statement checks if the value of 'x' is greater than 0.

If the condition is true, the code within the 'if' block is executed.

In this case, since 'x' is 5, which is greater than 0, the statement "x is positive" is printed.

The 'if' statement allows for conditional execution of code based on a specific condition.

If the condition is true, the code within the 'if' block is executed, otherwise, it is skipped.

The 'if' statement can be used on its own or in conjunction with other control flow statements such as 'else' or 'else if' to create more complex decision-making structures.
