STL之pair对组

#include<iostream>
#include<algorithm>
#include<cstring>
#include<cstdlib>
using namespace std;

//创建对组
void test01(){
    /*方法一：*/
    pair<int,int> pair1(10,20);
    cout<<pair1.first<<" "<<pair1.second<<endl;
    /*方法二：*/
    pair<int,string> pair2=make_pair(10,"aaa");
    cout<<pair2.first<<" "<<pair2.second<<endl;
    /*方法三：*/
    pair<int,string> pair3=pair2;

}
int main(){

    test01();
    return 0;
}
