In this chapter, we covered the basics of programming—from what variables are and how to store values in them, to looking at operators and statements, to how to decide when each is required. After that, we looked at iterators and functions, which can be used to make our job simpler and automate the code as much as possible. Arrays and pointers help us to group and store data of a similar type, and with struct and enum we can create custom data types. Finally, we looked at classes and inheritance, which is the crux of using C++ and makes it convenient to define our data types with custom properties.
In the next chapter, we will look at the foundation of graphics programming and explore how three-dimensional and two-dimensional objects are displayed on the screen.
