10.9. Dynamic Memory Management
You can control the allocation and deallocation of memory in a program for objects and for arrays of any built-in or user-defined type. This is known as dynamic memory management and is performed with the operators new and delete. We’ll use these capabilities to implement our
Array class in the next section.
You can use the
new operator to dynamically allocate (i.e., reserve) the exact amount of memory required to hold an object or built-in array at execution time. The object or built-in array is created in the free store (also called the heap)—a region of memory assigned to each program for storing dynamically allocated objects.2 Once memory is allocated in the free store, you can access it via the pointer that ...
