Hey Harry, It's a wonderful thing that you have wrote all code and documented it so well that i have bookmarked your repository!. Now that I've sugarcoated my only gripe is the exercises in the each chapter are given with such concepts in mind where we are only limited to the areas they are covered. For example the deck of cards exercise in the chapter 3 - Selections, the exercise is supposed to be done only with selections statements, logical and conditional expressions, but you have used arrays which is not gonna come until chapter 6. It was kind of a bummer but yeah i wrote my own code for it before looking at yours and I found this mismatch. Thanks if you have read so far.

Thanks again for the suggestions, I updated the exercises in Chapter 3 to use selection statements instead of arrays per chapter curriculum.
