What happens when a pointer is deleted twice
Answered by admin @
Answer:
If you delete a pointer and set it to NULL, it it possibly cannot have an adverse effect. It is safe. However, if a pointer is deleted an not nullified then it can cause a trap
Explanation:
I know that a "deleting the same memory twice" error can happen when two pointers address the same dynamically allocated object. If delete is applied to one of the pointers then the object's memory is returned to the free store. If we subsequently delete the second pointer then the free store may be corrupted.
