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 will lead to undefined behaviour and delete deallocates memory , it does not reinitialize it with zero .

If you want to make it zero out then do :

SingleBlock::~SingleBlock()

{    x = y = 0 ; }
