How can we overload the Binary Operator this such type of program are described here.

Binary Operator overloading

#include <iostream>
using namespace std;
class coord
{
    int x,y;
    public :
    coord(){x=0;y=0;}
    coord(int i,int j){x=i;y=j;}
    void get_xy(int &i,int &j){i=x;j=y;}
    coord operator +(coord ob2);
     coord operator -(coord ob2);
      coord operator *(coord ob2);
       coord operator /(coord ob2);
        coord operator =(coord ob2);
};
coord coord::operator +(coord ob2)
{
    coord temp;
    temp.x=x+ob2.x;
    temp.y=y+ob2.y;
    return temp;
}
coord coord::operator -(coord ob2)
{
    coord temp;
    temp.x=x-ob2.x;
    temp.y=y-ob2.y;

    return temp;

coord coord::operator =(coord ob2)
{
    coord temp;
    x=ob2.x;
    y=ob2.y;
    return *this;
