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

Dynamically allocated objects are your responsibility - you need to explicitly clean them up. Automatic objects (such as obj1) are cleaned up when the scope exits, automatically. In this case, before the scope exits - explicitly call delete obj2. NOTE: this line obj2 -> ~cl1 - does not do anything - the delete will take care of triggering the destructor correctly.
