/prog/ - c++ pointer fuckery

I need some help.

I'm working on a project that requires a dynamically-sized 2D array of object pointers. How would I go about creating such a thing? I'd like to go with C-style arrays (though if vectors would be easier I'll try it). Would I need to use a triple pointer? Also, I need each element in the array to be NULL when the array is allocated.

Your 2D array will be an 1D array. Nobody allocates N arrays of M for NxM. Allocate an array of size N*M instead.

Never in my life used a triple pointer. Double pointer is very common however.
