C++ delete - It deletes my objects but I can still access the data?

Question

I have written a simple, working tetris game with each block as an instance of a class singleblock.

class SingleBlock
{
    public:
    SingleBlock(int, int)         


        

Answer 1

It won't zero/change memory just yet... but at some point, the rug is going to be pulled from under your feet.

No it is certainly not predictable: it depends on how fast memory allocation/deallocation is churned.
