Overloading the comma operator

#include<iostream.h>
#include<conio.h>
#include<alloc.h>
#include<stdlib.h>
class loc{
int longitude,latitude;
public:
loc(){}
loc(int lg,int lt){
longtitude=lt;
}
void show()
{
cout<<longtitude<<"";
cout<<latitude<<"";
}
loc loc::operator,(loc op2)
{
loc temp;
temp.longtitude=op2.longtitude;
temp.latitude=op2.latitude;
return temp;
}
};
main()
{
clrscr();
loc ob1(10,20),ob2(4,6),ob3(1,1);
ob1.show();
ob2.show();
ob3.show();
ob1=(ob1,ob2,ob3);
ob1.show();
getch();
}

Output:
10 20
