They don’t apply to memory allocated by using the C++ new operator (or by using the older C malloc() function). We call that kind of memory dynamic memory. As you saw in Chapter 4, dynamic memory is controlled by the new and delete operators, not by scope and linkage rules. Thus, dynamic memory can be allocated from one function and freed from another function. Unlike automatic memory, dynamic memory is not LIFO; the order of allocation and freeing depends on when and how new and delete are used. Typically, the compiler uses three separate memory chunks: one for static variables ...
