Notes
C++ Style Casting
The casts shown in this video are C style casts (i.e. (int) or int()). C++ adds a new style of casting, with the syntax static_cast<int>(). This type of casting is more limited than C style, and thus safer in certain situations. It also has the advantage of making it easier to search a codebase for type casting. However, I have opted not to cover it at this point, mainly because the syntax is clumsy and I did not want to turn beginners off of the idea of explicit casting to clean up compiler warnings.
I will be covering C++ style casts in the future when they will prove be more relevant. Specifically, after we cover pointers, I will discuss the reinterpret_cast<> for reading data from disk into variables / structures. When I cover that topic, I will also mention static_cast<>. The other C++ casts will be mentioned when the topic arises organically over the course of the tutorials.
