What is the difference between delete and calling destructor in C++

Question

As stated in the title, here is my code:

class Foo {

    public:
        Foo (int charSize) {
            str = new char[charSize];
        }
        ~Foo (         


        

Answer 1

Calling a destructor releases the resources owned by the object, but it does not release the memory allocated to the object itself. The second code snippet has a memory leak.
