一、需求与分析

1. 项目概述

计算每个老师在一个学期中所教课程的总工作量。（教师单个教学任务的信息为：教师号、姓名、性别、职称、认教课程、班级、班级数目、理论课时、实验课时、单个教学任务总课时）

1.1 教师信息处理

(1) 输入教师授课教学信息，包括教师号、姓名、性别、职称、认教课程、班级、班级数目、理论课时、实验课时。

(2) 插入（修改）教师授课教学信息：

(3) 删除教师授课教学信息：

(4) 浏览教师授课教学信息：

1.2 教师工作量数据处理：

(1) 计算单个教学任务总课时。计算原则如下表：

班级数目	单个教学任务总课时
2	1.5*(理论课时+实验课时)
3	2*(理论课时+实验课时)
>=4	2.5*(理论课时+实验课时)

(2) 计算一个教师一个学期总的教学工作量。总的教学工作量=所有单个教学任务总课时之和。

(3)教师数据查询：

　　提示：输入教师号或其他信息，即读出所有数据信息，并显示出来。

1.3 教师综合信息输出

　　提示：输出教师信息到屏幕

2. 需求分析

高校教师工作量管理系统可以促进高校教学管理工作的顺利进行，推动教学质量的提升。该程序的主要功能包括教师号、姓名、性别、职称、课程、班级、班级数目、理论课时、实验课时的增删改查。

3. 模块设计

3.1 功能模块

根据课程设计题目的功能要求，各个功能模块的组成框图如下：

3.2 所有功能模块的流程图

二、设计与实现

1. 程序设计

1.1 教师工作量管理系统

teacher结构体数组主要用于储存教师单节课程的主要信息包含教师号、姓名、性别、职称、认教课程、班级、班级数目、理论课时、实验课时、单个教学任务总课时；

struct teacher {

    char name[20];//教师姓名

    char sex[20];//教师性别

    char num[20];//教师号

    char flag[20];//教师职称

    char course[20];//教师所教课程

    char classes[100];//教师所教班级

    int classnum;//教师所教班级数量

    int lilun;//理论课时

    int shiyan;//实验课时

    double all;//单个教学任务总课时

}teacher;

names结构体数组主要用于储存不重复的教师姓名、教师总工作量以及教师人数

struct names {

    char na[20];

    double sum;

    int num;

}names;

User结构体，用于储存注册者的姓名，id，性别以及密码

typedef struct User

{

    char id[15];

    char paw[20];

    char name[15];

    char sex[5];

}Users;

以下是一些用到的函数:

int Login();//普通用户登录

int Regist();//普通用户注册

int Change();//普通用户更改密码

int found();//普通用户找回密码

int Logins();//管理员登录

int Regists();//管理员注册

int Changes();//管理员更改密码

int founds();//管理员找回密码

int change();//更改教师信息

int put();//增加教师信息

int find();//查找教师信息

int cut();//删除教师信息

void show();//展示所有教师信息
