如题，4的数据在我的结构体内读不进去，始终是false和0，怎么会这样呢 代码如下：

#include <iostream>
#include <cstring>
#include <algorithm>

using namespace std;
int n,m;
struct tolls//玩具
{
    bool LR;
    string job;
}a[100100];
struct zhiling//指令
{
    bool LR;
    int direction;
}b[100100];

int main()
{
    cin>>n>>m;
    for(int i=0;i<n;i++){
        cin>>a[i].LR>>a[i].job;
    }
    for(int j=0;j<m;j++){
        cin>>b[j].LR>>b[j].direction;
    }
    int begin=0;
    for(int i=0;i<m;i++){
        //根据指令来动，在玩具人间移动
        if(a[begin].LR==0){//向内，左0-，右1+
            if(b[i].LR==0){
                begin-=b[i].direction;
                if(begin<0) begin+=n;
            }
            else{
                begin+=b[i].direction;
                if(begin>n) begin -=n;
            }
        }
        else{//向外，左0+，右1-
            if(b[i].LR==0){
                begin+=b[i].direction;
                if(begin>n) begin -=n;
            }
            else{
                begin-=b[i].direction;
                if(begin<0) begin+=n;
            }
        }
    }
    cout<<a[begin].job;
    system("pause");
    return 0;
}
