大家看看我的成绩管理。怎么就不行了呢？怎么了呢？
不能查询每个学生的数据了啊。看不出来。。。。。。脑子想大了。。这个文件：http://www.
代码：
#include <stdio.h>
#define C 40 //set line length
#define N 5 //set count of student
char name[N][10];
float mark[N][3];
char loading();
char line();

int search();
//----------------------------------------------------------------------------------

line(C); /*output '*'*/
printf("* 1. input data\n* 2. search score\n* 3. exit\n"); /* show interface*/

scanf("%d",&o);
