Overload the coord class so it can use coord object in operations in which an integer value can be multiplied by each coordinate. Allow the operations to use either order:
ob * int or int * ob.

//Overload the * for ob*int and int*ob.
#include
using namespace std;
class coord {
int x, y; /coordinate values
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;}
friend coord operator*(ob1, int i);
friend coord operator * (int i, coord ob2);
};
//Overload * one way
coord operator*(coord ob1, int i)
{
coord temp;
temp.x = ob1.x * i;
mp.y = ob1.y * i;
return temp;
}
// Overload * another way.
coord operator *(int i, coord ob2)
{
coord temp;
temp.x = ob2.x * i;
temp.y = ob2.y * ireturn temp;
}
int main()
{
coord o1(10, 10) o2;
int x, y;
o2 = o1 * 2; //ob * int
o2.get_xy(x, y);
cout << "(o1*2) x:" << x <<" y: << y << "\n"; = 3 * o1; //int * ob
o2.get_xy(x, y);
cout << "(3*o1) x: "<< x <<" y: "<< y <<"\n";
return 0;

Next: Overload the -- operator for the coord class. Create its both prefix and postfix forms
Previous: Using a friend, show how to overload the -- relave to the coord class. Define both the prefix and postfix forms.
