The syntax to access memory in C++ is straightforward. The & operator returns the address of an object. That object can be a variable, a built-in type or the instance of a custom type, or even a function (function pointers will be covered in the next chapter). The address is assigned a typed pointer variable or a void* pointer. A void* pointer should be treated as merely storage for the memory address because you cannot access data and you cannot perform pointer arithmetic (that is, manipulate the pointer value using arithmetic operators) on a void* pointer. Pointer variables are usually declared using a type and the * symbol. For example:
int i = 42; int *pi = &i;
In this code, the variable i is an integer, and ...
