题目：PAT 甲级 1062

为什么我用字符数组类型的考号是输入会错啊

以下是用int类型的代码可AC

#include <cstdio>
#include <algorithm>
#include<cstring>
using namespace std;
/*
*******************************************************************************
*********疑问:为什么Examinee的id项改成char id[10]之后会出错？？*******************
**********************输入部分哪里错了？求指教***********************************
*******************************************************************************
*/

struct Examinee
{
    //char id[10];
    int id;//考号
    int moral_score;//德分
    int capacity_score;//才分
    int examinee_rank;//考生等级

};

bool cmp(Examinee a, Examinee b)//sort()的比较函数
{
    if(a.examinee_rank!=b.examinee_rank) return a.examinee_rank<b.examinee_rank;
    else if((a.capacity_score+a.moral_score)!=(b.capacity_score+b.moral_score)) return (a.capacity_score+a.moral_score)>(b.capacity_score+b.moral_score);
    else if(a.moral_score!=b.moral_score) return a.moral_score > b.moral_score;
    //else return strcmp(a.id,b.id)<0;
    else return a.id<b.id;
}

int judgeRank(int moral_score,int capacity_score,int L,int H)//判断考生的等级
{
     if(moral_score<L ||capacity_score<L)
        return 5;

     if(moral_score>= H && capacity_score>=H)
        return 1;
     else if(moral_score>=H &&capacity_score<H&&capacity_score>=L)
        return 2;
     else if(moral_score<H &&capacity_score<H&&moral_score>=L&&capacity_score>=L&&moral_score>=capacity_score)
        return 3;
     else
        return 4;

}

int main()
{
    Examinee examinee[100010];
    memset(examinee,0,sizeof(struct Examinee)*100010);
    int N,L,H;
    scanf("%d %d %d",&N,&L,&H);
    int num_of_passed=N;
    for(int i = 0;i<N;i++)
    {
        //scanf("%s %d %d",examinee[i].id,&examinee[i].moral_score,&examinee[i].capacity_score);

        scanf("%d %d %d",&examinee[i].id,&examinee[i].moral_score,&examinee[i].capacity_score);

        examinee[i].examinee_rank = judgeRank(examinee[i].moral_score,examinee[i].capacity_score,L,H);
        if(examinee[i].examinee_rank == 5) num_of_passed--;
    }
    sort(examinee,examinee+N,cmp);
    printf("%d\n",num_of_passed);
    for(int i = 0 ;i<N;i++)
    {
        if(examinee[i].examinee_rank==5) break;
        //printf("%s %d %d\n",examinee[i].id,examinee[i].moral_score,examinee[i].capacity_score);
        printf("%d %d %d\n",examinee[i].id,examinee[i].moral_score,examinee[i].capacity_score);
    }

    return 0;
