#include<bits/stdc++.h> using namespace std; int main(){ cout<<"Nice to meet you"<<endl<<"Nice to meet you too"; return 0; }

#include<iostream> using namespace std; int main(){ cout<<"Nice to meet you\nNice to meet you too"; }

嘿嘿嘿嘿嘿嘿嘿

时间空间都很优 真是0ms

#include<bits/stdc++.h> using namespace std; int main() { cout << "Nice to meet you" << endl; cout << "Nice to meet you too" << endl; return 0; }

#include <iostream> using namespace std; int main() { cout<<"Nice to meet you"<<endl; cout<<"Nice to meet you too"<<endl; }

#include<bits/stdc++.h> using namespace std; int main(){ cout<<"Nice to meet you"<<'\n'<<"Nice to meet you too"; return 0; }

谢谢，简单到不用注释*2：

在我做第二个程序的时候你在哪里？？？

#include<bits/stdc++.h> using namespace std; void out(){ cout<<"Nice to meet you"<<endl; cout<<"Nice to meet you too"; } int main(){ out(); }

#include<bits/stdc++.h> using namespace std; int main(){ cout<<"Nice to meet you"<<endl; cout<<"Nice to meet you too"<<endl; }

#include<bits/stdc++.h> using namespace std; int main(){ cout<<"Nice to meet you"<<endl<<"Nice to meet you too"; return 0; }
