输入多个学生的学号、姓名和成绩，然后输出成绩最高学生姓名和学号。输入多组样例。每组样例包含一个整数N，代表有N个学生。下N面行依次输入学生学号、姓名和成绩。若N = 0，则输入结束

#include<stdio.h>
#include<string.h>
struct stu_inf{
char name[10];
char num[20];
short score;
};
int main(void)
{
struct stu_inf s_max;
short num_max = 0;
int input_num;
char stu_name[10];
char stu_num[20];
int stu_score;
scanf("%d", &input_num);
getchar();
for (int i = 0; i < input_num; i++)
{
scanf("%s %s %d", stu_num, stu_name, &stu_score);
if (stu_score > num_max)
{
num_max = stu_score;
strcpy(s_max.name,stu_name);
strcpy(s_max.num, stu_num);
}
}
printf("%s %s",s_max.num,s_max.name);
}
//请问还怎还才能做到输入多组数据，遇到0的时候输入结束？谢谢您！

#include<stdio.h>
#include<string.h>
struct stu_inf{
char name[10];
char num[20];
short score;
};
int main(void)
{
    struct stu_inf s_max[100];
    short num_max = 0;
    int input_num;
    char stu_name[10];
    char stu_num[20];
    int stu_score;
    scanf("%d", &input_num);
    getchar();

    for (int i = 0; i < input_num; i++)
    {
        scanf("%s %s %d", stu_num, stu_name, &stu_score);
        if (stu_score > num_max)
        {
            num_max = stu_score;
            strcpy(s_max[i].name,stu_name);
            strcpy(s_max[i].num, stu_num);
        }
    }

    for (int i = 0; i < input_num; i++)
    {
        printf("%s %s\n",s_max[i].num,s_max[i].name);
    }
}

#include <stdio.h>

struct stu_inf
{

    char num[20];
    short score;
};
int main(void)
{

    short num_max = 0;
    int input_num;
    char stu_name[20];
    char stu_num[20];
    int stu_score;
    while (1)
    {
        num_max = 0;
        scanf("%d", &input_num);
        if(input_num == 0) break;
        getchar();
        for (int i = 0; i < input_num; i++)
        {
            scanf("%s %s %d", stu_num, stu_name, &stu_score);
            if (stu_score > num_max)
            {
                num_max = stu_score;
                strcpy(s_max.name, stu_name);
                strcpy(s_max.num, stu_num);
            }
        }
        printf("%s %s\n", s_max.num, s_max.name);
    }
}

使用while循环
while(scanf("%d",&n),n!=0);
