用C++实现学生教师类的菱形继承

• 前言
• 功能介绍
• 结果展示
• 代码区

大半夜的又整了个活！
算是写的第二个C++代码，反正不是码农，随便写着玩玩，但无论怎样，用户体验第一，安全性第一！
好像不能兼得哦。反正安全性我也不太会，那就安全性第二吧。用户体验第一！

这个工程包括四个类，分别是人员类、学生类、教师类和学生教师混合类。
学生类和教师类虚继承人员类，混合类多继承学生类和教师类。
每个类包含各自的toString函数，拥有较完善的键入界面。

使用界面

创建人员对象

创建混合对象并打印

好了，懒得展示了，直接嫖吧

人员类

#include
#include
using namespace std;

//人员类
class Person {
public:
	Person(string name, int age) :m_name(name), m_age(age) { }
	string toString() {
		string str = m_name + "'s age is ";
		str += std::to_string(m_age);
		str += ".n";
		return str;
	}
private:
	int m_age;
	string m_name;
};

两个虚继承

//学生类
class Student : virtual public Person {
public:
	Student(int score, string name, int age) : m_score(score), Person(name, age) { }
	string toString(int key) {
		string str = "And his score is ";
		str += std::to_string(m_score);
		str += ".n";
		return str;
	}
	string toString() {
		return Person::toString() + toString(1);
	}
private:
	int m_score;
};
//教师类
class Teacher : virtual public Person {
public:
	Teacher(int salary, string name, int age) : m_salary(salary), Person(name, age) { }
	string toString(int key) {
		string str = "And his salary is ";
		str += std::to_string(m_salary);
		str += ".n";
		return str;
	}
	string toString() {
		return Person::toString() + toString(1);
	}
private:
	int m_salary;
};

一个多继承

//教师学生混合人员
class StuStaff : public Student, public Teacher {
public:
	StuStaff(int score, int salary, string name, int age)
		: Student(score, name, age), Teacher(salary, name, age), Person(name, age) { }
	string toString() {
		return Person::toString() + Student::toString(1) + Teacher::toString(1);
	}
};

交互菜单

//交互菜单
void makeMenu() {
	cout << "+----菱形继承模拟系统----+" << endl;
	cout << "|       0.退出系统       |" << endl;
	cout << "|  1.创建人员对象并打印  |" << endl;
	cout << "|  2.创建学生对象并打印  |" << endl;
	cout << "|  3.创建教师对象并打印  |" << endl;
	cout << "|  4.创建混合对象并打印  |" << endl;
	cout << "+------------------------+" << endl;
	cout << "请选择操作：";
}

按键交互

//按键交互
void keyDown() {
	int key;
	cin >> key;
	switch (key) {
	case(0):
		cout << "退出成功" << endl;
		exit(0);
		break;
	case(1): {
		cout << "请输入姓名和年龄：";
		string name;
		int age;
		cin >> name >> age;
		Person person(name, age);
		cout << person.toString();
		break;
	}
	case(2): {
		cout << "请输入姓名，年龄和分数：";
		string name;
		int age, score;
		cin >> name >> age >> score;
		Student student(score, name, age);
		cout << student.toString();
		break;
	}
	case(3): {
		cout << "请输入姓名，年龄和工资：";
		string name;
		int age, salary;
		cin >> name >> age >> salary;
		Teacher teacher(salary, name, age);
		cout << teacher.toString();
		break;
	}
	case(4): {
		cout << "请输入姓名，年龄,分数和工资：";
		string name;
		int age, score, salary;
		cin >> name >> age >> score >> salary;
		StuStaff stu(score, salary, name, age);
		cout << stu.toString();
		break;
	}
	default:
		break;
	}
}

主函数

int main() {
	
	while (1) {
		makeMenu();
		keyDown();
		system("pause");
		system("cls");
	}
	return 0;
}

整活结束！
