7.A program consists of two base classes and one derived class. The base class basic_info contains the data members: name, roll number and sex. Another base class academic_fit contains the data members: course, semester and rank. The derived class financial_assit contains the data member amount besides the data members of the base classes. The derived class has been declared as an array of class objects. The member functions are used to get information of the derived class from the keyboard and display the contents of the array of class objects on the screen.
