Question
If Sports will be a main class. Cricket, volleyball, badminton and Tic-Tac-Toe are concrete classes.
- For each of concrete classes, create member functions to SetNumberOfTeamMembers, GetNumberOfTeamMembers, GetNameOfGame and Select_Captain.
- Overload class constructor for Cricket and Volleyball classes by providing TotalNumber as argument.
- Create a friend function “get_players_list” to print the list of players from cricket and volleyball team.
- Overload Operator ‘+’ which will add 2 objects from Tic-Tac-Toe and will print total number of players from these objects.
- Depict polymorphic behavior of the classes by create references of the parent class to concrete objects.
