Loop Errors

To gain more practice with loops, as well as provide experience to read/fix someone else's code.

You will learn how the flow of control can be altered with different types of looping statements. You'll see the effect of braces in creating blocks of code, consider how complex boolean expressions are evaluated, and witness common pitfalls in programming conditional looping statements.

Your task for this lab is to fix a program that has several loops and several errors.
