Question

WRITE IN C++

Add to the Coord class

Edit the provided code in C++

Write a member function named

     int distance2origin()

that calculates the distance from the (x, y, z) point to the origin (0, 0, 0)

the ‘prototype’ in the class definition will be

     int distance2origin()

outside the class definition

            int Coord :: distance2origin()

{

                        // your code

}
