Write the program in c++ Create a common friend interest_cal() of three classes such as: Class A,B and C. Class A is having principle(float) private data member and inputA() public member function for taking input of principle, Class B is having rate(float) private data member and inputB() public member function for taking input of rate, Class C is having time(float) private data member and inputC() public member function for taking input of time. Friend function interest_cal() calculates and displays simple interest after accessing private members of class A,B and C respectively
