Why destructor is created?

#1

I could not understand what is the purpose of a destructor in this program

#2

Destructor is a member function which destructs or deletes an object.

A destructor function is called automatically when the object goes out of scope

If we do not write our own destructor in class, compiler creates a default destructor for us.

The default destructor works fine unless we have dynamically allocated memory or pointer in class.

When a class contains a pointer to memory allocated in class, we should write a destructor to release memory before the class instance is destroyed. This must be done to avoid memory leak.
