6我上次模拟考做了这一题
```cpp
#include<iostream>
#include<string>
#include<vector>
#include<utility>
using namespace std;
vector<pair<string,int>> vec;
int n,m;
int main(){
ios::sync_with_stdio(false);
cin>>n>>m;
for(int i=0;i<n;i++){
string s;
int c;
cin>>c>>s;
vec.push_back(make_pair(s,c));
}
int ind=0;
for(int i=0;i<m;i++){
int fac,move;
cin>>fac>>move;
if(vec[ind].second==0){
if(fac==0)
ind-=move;
if(fac==1)
ind+=move;
}else{
if(fac==0)
ind+=move;
if(fac==1)
ind-=move;
}
ind+=n*100;
ind%=n;
}
cout<<vec[ind].first;
}
```

@[super_LD](/user/802760) 你没有包含```<string>```头文件

@[diamond_153](/user/751417) 可我后面用万能头文件也是不能输入。

string是输入字符串，你想输入字符数组要用char
