If I never call “new,” do I ever have to call “delete”?

Question

If I manage to construct objects in C++ by doing

Object o;

instead of

Object *o = new Object();

in every case, do I ever need to call delete or will all memory be managed automatically?

Answer 1

No. That object is allocated on the stack, and will be destroyed automatically when it goes out of scope. That includes freeing its memory and calling the destructor.

Answer 2

You cannot call delete on an object that was not allocated with new . Objects will be destroyed when they go out of scope.
