This is a good way to do it. You can also do vector<int> with size sizeX*sizeY for some nice extra safety.

The best thing is to wrap this code in a class - you can perform a clean-up in destructor and you can implements methods get(x, y) and set(x,y, val) instead of forcing user to do multiplication by himself. Implementing operator[] is more tricky, but I believe it's possible.
