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
