Mastery 19 - Validated User Input
At some point working with your programming classes or experiences you will try your friends or someone else to try to use you programs, and you will know someone that will like to mess with the program. What do I mean?
If the program asks the user to introduce a number and they write a letter the program will mark an error. So the validated user input helps us to manage this kind of situation just as shown in the code in the photo.
