Çalıştığım kitaptan bir örnek:
#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; }
friend ostream &operator << (ostream &stream, coord ob);
};
ostream &operator << (ostream &stream, coord ob) {
stream << ob.x << ", " << ob.y;
return stream;
}
int main() {
coord a(1,1), b(10, 23);
cout << a << endl;
cout << b << endl;
return 0;
}
Let`s make this world a better place to live !
