我做过一个类似的只是数据结构不一样（但也是学生的）
你看懂了这个你就自己会编了
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int M=3;//用户数
int N=7;//学生数

struct birthday
{
int year;
int month;
int day;
};
struct score
{
int English;
int Math;
int Clanguage;
};
struct student//学生
{
char academy[10];
char remove[10];
int number;
char name[10];
char sex;
char adress[20];
struct birthday birday;
struct score grade;
}stu[50];

struct student p[50];

struct user//用户
{
char name[10];
char password[10];
int GF;
}use[10];

void bbb();/*初始化用户信息存在myfile1.txt*/
void aaa();/*初始化学生信息myfile.txt*/
void ccc();/*初始化学生与用户的个数*/
void startget();/*将文件的数据读入到数组中use[10]，p[50]*/

void main()
{
aaa();
bbb();
ccc();
printf("安装完成！\n");
printf("按回车键结束！\n");
getchar();
startget();
printf("初始化话成功！\n");
printf("按回车键结束！\n");
getchar();
/*****下面你就可以用数组use[10]，p[50]了，数据初始化了***********/
//////////////////////////////////////////////////////////////////
}
void aaa()
{
struct student stu[50]={{"计算机","软件041",1,"张东",'m',"北京",{87,8,7},{80,90,85}},
{"计算机","软件041",2,"于南",'m',"上海",{86,11,7},{98,80,95}},

fclose(pf);

N=b[0],M=b[1];
