Answer to Question #214849 in C++ for Charan

Question

Create a class called DISTANCE with data members as feet (int) and inches (float), use parameterised constructor to get the input values of the data members. Write a function to display the output. Create another class called DIST_KM with a data member kilometre (float). Use a parameterized constructor to assign input and a function to display it. In the main function, write a menu-driven program with 1. Convert feet and inches into kilometres 2.Check whether both the distances are equal or not. For option 1, write the conversion function in the source class. For option 2, create a separate object to assign the kilometres and check the equality of distances by overloading the operator (==).  [Note: 1 feet=0.00305km]
