Question

If I want to delete a dynamically allocated array of primitive type values:

int *it = new int[10]

do I just put delete [] it in the destructor to take care of releasing memory properly?

OR

Realizing that, as a pointer is a primitive type, does deleting a dynamically allocated array involve doing something like this in the destructor:

for (size_t idx = 0; idx != 5; ++idx)
        delete sp[idx];
    delete[] sp;

I’m rather confused about this as I am having a lot of memory related errors in my program.

If you have:

int* it = new int[10];

the correct way to delete it is:

delete[] it;

If you have a member variable of this type you need to implement a copy constructor and assignment operator as the default versions of these are not sufficient or make the class uncopyable.

As this is C++ I would suggest using std::vector<int> instead as this will handle the memory management for you.
