C++实现学生选课系统的思路与详细过程

C语言是在国内外广泛使用的一种计算机语言,下面这篇文章主要给大家介绍了关于C++实现学生选课系统的思路与详细过程,文中通过实例代码介绍的非常详细,需要的朋友可以参考下

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;

C++实现学生选课系统的思路与详细过程

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<course> 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
};

函数实现

1) void print();向屏幕输出课程信息

void course::print()
{
	system("cls");
 
	for (int i = 0; i < c.size(); i++)
	{
		cout << "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━" << endl;
		cout << endl << "课程编号:" << c[i].number << "   课程名称:" << c[i].name << "   课程学分:" \
			<< c[i].credit << "   授课老师:" << c[i].teachername << endl;
	}
 
	cout << "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━" << endl;
	cprintorget();
}

2)void get();指定课程的信息,用课程编号获取

void course::get()//获得课程信息
{
	system("cls");
	long k = 1, kk;
 
	cout << "*************请输入要查询的课程编号**************" << endl;
	
	cin >> kk;
	if (ishave(kk))
	{
		for (size_t i = 0; i < c.size(); i++)
			if (c[i].number == kk)
			{
				cout << endl << "课程编号:" << c[i].number << "   课程名称:" << c[i].name << "   课程学分:" \
					<< c[i].credit << "   授课老师:" << c[i].teachername << endl;
				break;
			}
	}
	else
	{
		cout << "*************没有该课程******************" << endl;
	
	}
	cprintorget();
}

3)void add();增加一个课程的信息

void course::add()
{
	system("cls");
	long k = 1; course c1;
	cout << "$        请输入要添加的课程编号:      $" << endl;
	cin >> c1.number;
	while (ishave(c1.number))
	{
 
		system("cls");
	
		cout << "***************************************" <<endl;
		cout << "        该课程已添加,请重新输入:       " << endl;
		cout << "              (按0退出)               " << endl;
		cout << "***************************************" << endl;
		cin >> k;
		if (k == 0)
		{
			cinfo();
			break;
		}
		else c1.number = k;
 
	}
	if (k != 0)
	{
		
		cout << "$           请输入课程名称:           &" << endl;
		cin >> c1.name;
		cout << "****************************************" << endl;
		cout << "            请输入课程学分:             " << endl;
		cout << "****************************************" << endl;
		cin >> c1.credit;
		cout << "****************************************" << endl;
		cout << "          请输入授课老师名称:            " << endl;
		cout << "****************************************" << endl;
		cin >> c1.teachername;
		system("cls");
		c.push_back(c1);
		cinfo();
	}
}

4)void del() ; 删除某个课程信息(老师)

void course::del()//老师删除课程信息
{
	system("cls");
	long k = 1, kk;
	cout << "***************请输入要删除的课程编号****************" << endl;
	cin >> kk;
	if (ishave(kk))
	{
		for (auto p = c.begin(); p != c.end();)
		{
			if (p->number == kk)
			{
				p = c.erase(p);
				break;
			}
			else
				++p;
		}
		cout << "***************成功删除该课程********************" << endl;
		
}
	else
	{
		
		cout << "****************你还没有添加该课程****************" << endl;
	}
}

5)void edit();修改课程信息(老师)

void course::edit()//老师修改课程信息
{
	system("cls");
	long k = 1, kk;
	cout << "       请输入要修改课程的课程编号:     " << endl;
	cin >> kk;
	if (ishave(kk))
	{
		for (size_t i = 0; i < c.size(); i++)
		{
			if (c[i].number == kk)
			{
				system("cls");
				cout << "          请重新输入课程名称:           " << endl;
				cin >> c[i].name;
				cout << "          请重新输入课程学分:           " << endl;
				cin >> c[i].credit;
				cout << "         请重新输入授课老师名称:         " << endl;
				cin >> c[i].teachername;
				cout << "              修改成功。                 " << endl;
				break;
			}
		}
	}
	else
	{
		cout << "              没有该课程 。             " << endl;
 
	}
 
}

6)void ishave(long si);查询是否有该课程

int course::ishave(long si)//查询是否有该课程
{
	for (size_t i = 0; i < c.size(); i++)
		if (c[i].number == si)
			return true;
	return false;
}

7)void print();打印学生的信息

void student::print()//打印所有学生信息
{
	long sumk = 0;
	system("cls");
	for (int i = 0; i < s.size(); i++)
	{

		cout << "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━" << endl;
		cout << endl << "学生学号:" << s[i].number << "   姓名:" << s[i].name << "   性别:" \
			<< s[i].sex << "   年级:" << s[i].grade << endl << endl\
			<< "学生已选课程:" << endl;
		if (s[i].havec.size() == 0)
		{
			cout << "无" << endl;

		cin >> k;
		if (k == 0)
		{
			sinfo();
			break;
		}
		else s1.number = k;
 
	}
	if (k != 0)
	{
		cout << "             请输入学生姓名:            " << endl;
