Will this memory be freed properly?

Question

I have a pointer to a pair, suppose std :: pair <A *, B *> * pointerpair. I allocated its memory, and after using the pair, I call delete pointerpair.

Will it also cause delete A and delete B and completely free the memory?

If I just call delete A and delete B but not delete pointerpair, is that a memory leak?

Answer 1

no.............

Answer 2

No. He will not do this automatically. You must delete it explicitly.
