bookChallenge: If Statement

Understanding the if Statement

An if statement is a fundamental building block in C programming that enables you to control how your program behaves based on specific conditions. You use an if statement to check if a condition is true or false. If the condition is true, the code inside the block runs; if it is false, the code is skipped.

You use if statements to help your program make decisions, such as:

  • Checking if a user's input matches a required value;
  • Determining if a number is positive, negative, or zero;
  • Executing certain actions only when specific criteria are met.

By using if statements, you ensure that your program responds intelligently to different situations. In C, only the code inside the braces {} following the if statement will run when the condition evaluates to true. This allows you to create flexible and dynamic programs that can handle a wide range of real-world scenarios.

    if (number > 5) {
        printf("The number is greater than 5\n");
    }

Create a function named calculateBonus that calculates a fitness bonus based on the number of steps taken.

  • Initialize a variable bonus with 0;
  • Use an if statement to check if steps is 10,000 or more;
  • If the condition is true, set bonus to steps multiplied by 0.05;
  • Return the value of bonus.
