Explanation

If the derived class and the base class contain a member with the same name, it is called 'Member Overriding'. For example, there is a class named 'A', which has a function named 'show()'. If we declare a child class of 'A' named 'B' and declare a function with the same name show () in B, the show() declared in B will hide the show() declared in A. If an object of class B' makes a call of show() , the one defined in the child class(B) will be processed. If an object of the base class makes a call to show(), then the one defined in the base class will be called.
