Process memory
The stack and the heap are the two most important memory segments in a C++ program. There is also static storage and thread local storage, but we will talk more about that later. Actually, to be formally correct, C++ doesn't talk about stack and heap; instead, it talks about the free store, storage classes, and the storage duration of objects. However, since the concepts of stack and heap are widely used in the C++ community, and all the implementations of C++ that we are aware of use a stack to implement function calls and manage the automatic storage of local variables, it is important to understand what stack and heap are.
In this book, I will also use the terms stack and heap rather than the storage duration of objects. I will use the terms heap and free store interchangeably and will not make any distinction between them.
Both the stack and the heap reside in the process' virtual memory space. The stack is a place where all the local variables...
