$(4$pts$)$ In $C++,$ write three classes which show an example of True Multiple Inheritance, for example Class $C$ is from both Class A and Class B$.$ Class A and B both have a function has the same name $($i$.$e$,$ func$\_$a$),$ how Class $C$ create a func$\_$a$,$ which will call func$\_$a from both Class A and Class B$?$ Can you find another way to call func$\_$a in Class A and Class B from Class C separately?
