Question

int *ptr_Array;
ptr_Array = new int[5];

Is it possible to remove the last element in the array?
I can PUSH the ints on one at a time.
I can delete the whole array.

delete []ptr_Array;
ptr_Array = NULL;

I can’t find a way to POP the elements off.

I tried the following and loads of other attempts.

ptr_Array[i_IastItem] = NULL; 

I just can’t figure it out, I have been trying all day.

You can by using a std::vector instead.

std::vector<int> x;
x.push_back(42);
x.pop_back();
