源代码:
一、项目要求 (1)学生有自己的 ID、姓名 、年级 、选课信息等;
(2)学生可以进行对已选课程的增删改查;
(3)每个课程有自己的学分,授课老师等;
二、模块分析
分析: 我们首要的首要的任务就是先对模块进行划分;从项目的要求出发;该系统可以大致分为两大类;
课程类(用来保存每门课程的信息,例如编号,名称,学分,授课教师);
学生类(用来保存每个学生的信息;例如编号,名字,性别。年级,分数);
对于这两个类来说;他们拥有相同的一点;就是编号和名称;所以可以脱出一个类用其他两个类来继承它;
设计思路 首先思考:打造一个火车那就先建造每一节车厢 ;而车厢就像是一个货物清单;用c++的类来实现;当一个车厢建造出来之后;最后就是用工具将它连接起来;
对项目分析:
(1)首先设计两个火车,一个是课程的;一个是学生的;
(2)每个火车都有自己的属性和成员;
(3)学生火车可以操作课程火车;

类实现:(也就是每一节车厢的模板)
1)基类(信息类)
目的:保存学生和课程共有的属性也就是,编号和名称;
class info
{
protected:
long number;
//编号
string name;
//名称
public:
info() {}
info(long num, string name) :number(num), name(name) {}
};
2)课程类;(公有继承信息类)
class course : public info//课程类
{
private:
int credit;
//学分
string teachername;
//授课教师
public:
course() {}
course(long num, string name, int cre, string tea) : info(num, name)
{
credit = cre;
teachername = tea;
}
course(const course& c1)
{
number = c1.number;
name = c1.name;
credit = c1.credit;
teachername = c1.teachername;
}
static void print();
//输出数据
static void get();
//获取数据
static void add();
//增加数据
static void del();
//删除数据
static void edit();
//修改数据
static int ishave(long si);
//查询是否有该课程
};
3)学生类(公有继承信息类)
class student : public info//学生类
{
private:
string sex;
//性别
string grade;
//年级
long scredit;
public:
vector havec;
//查询学生选课信息
student() {}
student(long num, string name, string se, string gra, long scr) : info(num, name)
{
sex = se;
grade = gra;
scredit = scr;
}
static void print();
//输出数据
static void get();
//获取数据
static void add();
//增加数据
static void del();
//删除数据
static void edit();
//修改数据
static int ishave(long si);
//查询是否有该学生
static void addcourse();
// 为学生添加课程
static void delcourse();
//为学生删除课程
static int ishavec(long si);
//查询该学生是否有该课程
