Question

Differentiate between static data members and non-static data members. 

Answer 1

S. No.	Static data member	Non-static/Ordinary data member
1.	All class objects share a single copy of this variable.	Each item creates a copy of the data.
2.	It can be accessed without requiring an instance of the class.	Using it requires first constructing a class instance.
3.	Static variables are allocated only once during class loading.	Each new object creates additional memory allocations for these variables.
