C語言實現(xiàn)學生信息管理系統(tǒng)(文件版)
更新時間：2022年06月20日 10:53:11 作者：CM666_
這篇文章主要為大家詳細介紹了C語言實現(xiàn)學生信息管理系統(tǒng)，文中示例代碼介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們可以參考一下
本文實例為大家分享了C語言實現(xiàn)學生信息管理系統(tǒng)的具體代碼，供大家參考，具體內容如下
下面是我自己用寫的學生信息管理系統(tǒng)，為了增加數(shù)據(jù)的利用率，分為學生端和教師端，同時實現(xiàn)賬號密碼登錄，以文件的形式將其存入。
代碼如下
#include <stdio.h>
#include <string.h>
#include <string>
#include<Windows.h>
#define USER "TOM" // 事先定義用戶名，用于登錄頁面，驗證身份。
#define PW "123456789" // 事先定義密碼 ，作用同上。
void Level_menu();//主菜單的聲明--選擇學生端還是老師端。
void Level_2_menu(); //二級菜單——具體功能分化
void Student_add_Level_3_menu();// 增添學生信息菜單功能分化
void Student_Insert(); //添加單個學生信息
void Student_Insert1(); /*為上面批量輸入設置的函數(shù)，其代碼與上面的
單個輸入相似，刪減了一部分*/
void Student_Tongji_menu();//統(tǒng)計菜單部分
void Student_Tongji_menu2();//統(tǒng)計二級菜單
void Student_Tongji_menu3();//統(tǒng)計
void IO_ReadInfo();/*將學生信息從文件（student database.txt）中讀出*/
void IO_WriteInfo();/*將學生信息寫入文件（Database.txt）*/
void student_Delete_menu(); /*刪除學生信息菜單*/
void student_menu1();/*學生查詢課程信息菜單*/
void student_Kecheng_menu2();
void Student_From_high_to_low1(); /*按綜合測評從高到低排序*/
void jiangxue_menu();/*獎學金評定辦法*/
void Student_Display2();/*顯示學生信息2在獎學金評定時使用*/
/*定義學生結構體*/
struct Student
{
char ID[20]; //學號
char Name[20]; //姓名
char sushe[6]; //宿舍房間號

float software; //軟件技術導論
float china_history;//中國近代史綱要
float junshi; //軍事教育
float xinli; //心理健康輔導
