Destructor not being called when leaving scope

Question

I am learning memory management in C++ and I don\'t get the why only some of the destructors are called when leaving scope. In the code below, only obj1 destructor is called

Answer 1

Destructors are called automatically when an object that was created on the stack goes out of scope.

With dynamically allocated objects, you need to call delete obj. delete will automatically call your destructor for you.
