C++ deleting a pointer to a pointer

Question

So I have a pointer to an array of pointers. If I delete it like this:

delete [] PointerToPointers;

Will that delete all the pointed to po

Answer 1

Let's take a (pseudocoded) real world example .Imagine that you had a class like this:

class Street
{
    public:
        Street();
        ~Street();
    private:
        int HouseNumbers_[];
}

typedef *Street StreetSign;

If you have an array of street signs, and you delete your array of streetsigns, that doesn't mean that you automatically delete the sreets. They re still there, bricks and mortar, they just don't have those signs pointing to them any more. You have got rid of those specific instances of pointers to the streets.

An array of pointers is (conceptually) a bit like an array of integers, it's an array of numbers representing the memory locations of various objects. It isn't the objects themselves.

If you delete[] the array of pointers, all you have done is delete an array of integers.
