[编程题]成绩排名 (20)
- 热度指数：3907 时间限制：C/C++ 1秒，其他语言2秒 空间限制：C/C++ 32M，其他语言64M
- 算法知识视频讲解
读入n名学生的姓名、学号、成绩，分别输出成绩最高和成绩最低学生的姓名和学号。
输入描述:
每个测试输入包含1个测试用例，格式为
第1行：正整数n
第2行：第1个学生的姓名 学号 成绩
第3行：第2个学生的姓名 学号 成绩
... ... ...
第n+1行：第n个学生的姓名 学号 成绩
其中姓名和学号均为不超过10个字符的字符串，成绩为0到100之间的一个整数，这里保证在一组测试用例中没有两个学生的成绩是相同的。
输出描述:
对每个测试用例输出2行，第1行是成绩最高学生的姓名和学号，第2行是成绩最低学生的姓名和学号，字符串间有1空格。

水题吧，砍瓜切菜。。。
记录最大、最小得分，如果超过了两个界限值，更新记录的信息即可。
#include <iostream>
(720)#include <cstring>
using namespace std;
int main() {
//最大分数、最小分数，注意初始化赋值
int n = 0, maxScore = 0, minScore = 100, score = 0;
//最大得分者的name、no、最小得分者的name、no
char maxName[11], maxNo[11], minName[11], minNo[11], name[11], no[11];
scanf("%d", &n);
for (int i = 0; i < n; ++i) {
scanf("%s %s %d", name, no, &score);
if (score > maxScore) {
//超过了已有的最大分数，更新
maxScore = score;
strcpy(maxName, name);
strcpy(maxNo, no);
}
if (score < minScore) {
//小于已有的最小得分，更新
minScore = score;
strcpy(minName, name);
strcpy(minNo, no);
}
}
printf("%s %s\n%s %s\n", maxName, maxNo, minName, minNo);
return 0;

同样的例子我在编译器没问题，但是在这里就错？？
请大佬康康#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[]) {
int num, score, i, j, minscore = 101, maxscore = -1, count = 0;
char sname[10],sno[10];
char min_sname[10], max_sname[10], min_sno[10], max_sno[10];
scanf("%d",&num);
for(i = 0; i < num; i++){
scanf("%s %s %d",sname, sno, &score);
if(score>maxscore){ // 找最高分
maxscore = score;
for(j = 0; j < 10; j++){
max_sname[j] = sname[j];
max_sno[j] = sno[j];
count = j;
}
max_sname[count] = '\0';
max_sno[count] = '\0';
}
if(score<minscore){ // 找最低分
minscore = score;
for(j = 0; j < 10; j++){
min_sname[j] = sname[j];
min_sno[j] = sno[j];
count = j;
