Since we are covering the use of variables, it is worth explaining the syntax used to define pointers and arrays because there are some potential pitfalls. Chapter 4, Working with Memory, Arrays, and Pointers, covers this in more detail, so we will just introduce the syntax so that you are familiar with it.
In C++, you will access memory using a typed pointer. The type indicates the type of the data that is held in the memory that is pointed to. So, if the pointer is an (4 byte) integer pointer, it will point to four bytes that can be used as an integer. If the integer pointer is incremented, then it will point to the next four bytes, which can be used as an integer.
Don't worry if you find pointers confusing at this point. ...
