[C++] 클래스 표준 입출력

C++의 연산자 오버로딩을 활용해 클래스를 직접 cin, cout에 사용할 수 있다.

x
ostream& operator << (ostream& os, const T& t)
{
    os << t.name << " " << t.a << " " << t.b << " " << t.c;
    return os;
}
istream& operator >> (istream& is, T& t)
{
    is >> s.name >> t.a >> t.b >> t.c;
    return is;
}

x
int main(void) {
    T t;
    cin >> t;
    cout << t << endl;
​
    return 0;
}
