operator_over_3.cpp

// In the following C++ program, two classes representing 
// geographical coordinates (longitude and latitude) are defined. 
// The program uses operator overloading to add two coordinate objects together.

// What will be the output of the program when executed?
// Identify and correct any errors in the code, if present.
// Explain how operator overloading is implemented in this code.
