In C++ operator<< is called the "Insertion Operator" and operator>> is called the "Extraction Operator"

These are commonly overloaded for individual classes for example:

struct foo{string bar;};

ostream& operator<<(ostream& os, const foo& bar){
    os << foo.bar;
    return os;
}

istream& operator>>(istream& is, const foo& bar){
    is >> foo.bar;
    return is;
}

foo can be used as follows:

foo bar;

cin >> bar;
cout << bar;
