Count the created objects using static member function in C++
Static data member
A static data member is also known as "Class Member" and it is available for all classes. In other words – we can say "A static data member is just like a global variable for a class". Generally, static data members are used to maintain the common things related to the class, like counting the objects etc.
Static Member Function
A static member function is used to access or manipulate the static data member, other data member cannot be used with a static member function.
