Am I freeing ptr1-3, when freeing ptr4?
From what I read in C++ Primer Plus this wouldn't work since ptr2,ptr3, and ptr4 are not considered pointers but ordinary int variables, the statement would have to be:
int* ptr1 = NULL, *ptr2 = NULL, *ptr3 = Null, etc...
Aye. Although if we ignore that then the answer is still no:
You don't delete pointers. You delete allocations.
