3. Before using free, make sure that the free pointer is! If it is NULL, delete is not required.
4. The free memory is a memory space pointed to by the pointer, which should be empty. The deleted memory does exist.

5. The following example shows the differences:
Malloc and free (and their variants) cause problems because they are too simple: they do not know constructors and destructor.

In fact, you do not even know the number of objects in the array, because you do not know the size of each object. Operator new [] of the base class is used to allocate memory to the array of the subclass object through inheritance, and the subclass object is usually larger than the base class. Therefore, it cannot be assumed that the size of each object in base: Operator new [] is sizeof (base). That
