Small Steps I — Creating with Text and Numbers

Running only when a condition holds

Print Positive only when number is greater than 0. Test with 3 first.

What you will learn

A condition is an expression that can be true or false. if is a conditional statement that runs the code inside its braces only when the condition is true.

Try it

Example · example.cpp

void small_main()
{
    int score = 80;
    if (score >= 60)
    {
        print("Pass");
    }
    print("Done");
}

score >= 60 asks whether the score is at least 60. With 80, it is true and prints Pass. Change it to 50: Pass is skipped and only Done is printed.

> means greater than, < less than, >= at least, and <= at most. Do not put a ; after the closing brace of if.

Expected output:

Pass
Done

Exercise

Print Positive only when number is greater than 0. Test with 3 first.

Exercise starter · exercise_starter.cpp

void small_main()
{
    int score = 80;
    if (score >= 60)
    {
        print("Pass");
    }
    print("Done");
}

Hint

Also change 3 to 0 and -1. Those cases should produce no output.
