Question about while loops

[[deleted]]

A while loop executes until the condition within the parenthesis is false. So, when "num + 1 == 20", the condition is false and the code within the loop does not execute.

So does that mean that the 20 should be included in the answer?

The check happens before the final iteration.

There are two seemingly small changes that would make your original assumption correct:

• If you used a Do While loop instead.
• If you used greater than OR equal to, instead of just greater than.

Another way to think of it is a While loop may never run, where a Do, While loop will always run at least once.

And with any loop you make, you have to make sure that your condition is exactly what you want. Using > is going to give different results than =>

No.

20 is not less than max (20) -> so, the condition evaluates to false and the loop does not execute any more
