|
Overload the operator << so it outputs a playing card in a nicely formatted style.
Let us write these functions for the type rational:
class rational {
public:
friend ostream&
operator<<(ostream& out, rational x);
friend istream&
operator>>(istream& in, rational& x)
.....
private:
long a, q;
};
ostream& operator<<(ostream& out, rational x)
{
return (out << x.a << " / " << x.q << '\t');
}
Click the Exercise link below to overload the operator << so it outputs a playing card in a nicely formatted style.
