What is a while statement?
A while statement is a control flow statement in code that tells your program to repeat a section of code until a certain criterion is met. In English, sometimes you may want to repeat a certain action until the desired result is met. An example of this could be you want to walk a mile a day until you lose 10 pounds. Once you lose 10 pounds you no longer want to walk a mile every day. You will keep repeating the action of walking until the criteria is met of you losing 10 pounds.
