	char number[8];
public:
	CPhone() { };
	CPhone(char *_name, char *_number) {
		strcpy(name, _name);
		strcpy(number, _number);
	}
	friend ostream &operator << (ostream &stream, CPhone o);
	friend istream &operator >> (istream &stream, CPhone &o);
};

ostream &operator << (ostream &stream, CPhone o) {
	stream << o.name << " ";
	stream << o.number << endl;
	return stream; 
}

istream &operator >> (istream &stream, CPhone &o) {
	cout << "Enter name: ";
	stream >> o.name;
	cout << "Enter number: ";
	stream >> o.number;
