[C/C++] STL pair, tuple 사용법

C++에 튜플이 있는지 첨 알았다!!! WOW

 

#include<bits/stdc++.h>
using namespace std;

pair<int, int> p;
tuple<int, int, int> t;
int a, b, c;

int main() {
	// 원래 방법 
	p = make_pair(1, 2);
	t = make_tuple(1, 2, 3);
	
	a = p.first;
	b = p.second;
	cout << a << " " << b << "\n";
	
	a = get<0>(t);
	b = get<1>(t);
	c = get<2>(t);
	cout << a << " " << b << " " << c << "\n";
	
	// tie 함수를 이용하는 방법 
	p = {1, 2};
	t = make_tuple(1, 2, 3);
	
	tie(a, b) = p;
	cout << a << " " << b << "\n";
	 
	tie(a, b, c) = t;
	cout << a << " " << b << " " << c << "\n";
}
