delete[] mechanics

[ninja9578]

Don't have to call destructors on primitives.

char * array = new char[5];
delete[] array;

No dtors.

Also, you don't need to know the number of elements to call of the destructors. You can easily determine that by total_allocated_space / sizeof(element). In fact, the iterating is probably done by using a running pointer, not an index anyway. My guess is that most compilers record the size of the space, not the number of items, because in the end, new[]/delete[] uses malloc / free. free doesn't care how many items is in it, just how many bytes.
