题解:

模拟题。注意看清题目,那几个要修改的字母真的很容易看错。。。还是输出时候的单复数形式。。。

代码:

#include<cstdio>
#include<cstring>
#include<cmath>
#include<string>
#include<set>
#include<vector>
#include<algorithm>
using namespace std;
struct student
{
    char id[15];
    char pwd[15];
    bool changed;
} stu[1005];
int main()
{
    int n,len,countx=0;
    bool changed=false;
    scanf("%d",&n);
    for(int i=0; i<n; ++i)
    {
        scanf("%s%s",stu[i].id,stu[i].pwd);
        len=strlen(stu[i].pwd);
        stu[i].changed=false;
        for(int j=0; j<len; ++j)
        {
            if(stu[i].pwd[j]=='1')
            {
                stu[i].pwd[j]='@';
                stu[i].changed=true;
            }
            if(stu[i].pwd[j]=='0')
            {
                stu[i].pwd[j]='%';
                stu[i].changed=true;
            }
            if(stu[i].pwd[j]=='l')

    }
    if(!changed)
    {
        if(n<2)
            printf("There is %d account and no account is modified\n",n);
        else
            printf("There are %d accounts and no account is modified\n",n);
    }
    else
    {
        printf("%d\n",countx);
        for(int i=0; i<n; ++i)
            if(stu[i].changed)
                printf("%s %s\n",stu[i].id,stu[i].pwd);
    }
