 OOP 313304 Practical No.8: Write a program to Implement Static Data Member

A typical use of static members is for recording data common to all class objects. The static data member is used as a counter to store the number of objects created by a particular class type.

Static data members are class members who are declared to be using static keywords. A static

member has certain special characteristics which are as follows: Only one copy of that member is created for the entire class and is shared by all the objects of that class, no matter how many objects are created.

• It is initialized before any object of this class is created, even before the main starts.
• It is visible only within the class, but its lifetime is the entire program.
