C++ Program: Single Inheritance

 /* 

13 C++ Program Single Level Inheritance

Create a base class containing the data member roll number and name.

Also create a member function to read and display the data using the concept of

single level inheritance. Create a derived class that contains marks of two

subjects and total marks as the data members.
