This book is an introduction to programming using C++. I assume that the reader has no previous programming experience. My goal is to focus on 'worked' coding examples to explain how to program. Most of what I write will be in the context of a code example. The code will always be the priority but I have also added text, pictures, screenshots, and videos that refer to the code.
These examples are called code playbacks. They animate the construction of some code that I have written. I will use them to show how a program grows from an empty file to a functioning program. I will explain the basics of C++ programming by telling the story of how programs grow. For each of the playbacks below simply click on the comments on the left hand side of the screen to move through the code.
