Operator OverloadingAn operator function is created using the
keyword operator. Operator functions can be either members or
nonmembers of a class. Nonmember operator functions are almost
always friend functions of the class
Creating a Member Operator FunctionA member operator function
takes this general form:ret-type class-name::operator#(arg-list){//
operations}Operator functions return an object of the class they
operate on,
But ret-type can be any valid type.
The # is a placeholder. When you create an operator function,
substitute the operator for the #.
First example of operator overloading.#include using namespace
std;class loc {int longitude, latitude;public:loc() {}loc(int lg,
int lt) {longitude = lg;latitude = lt; }void show() {cout
