实践练习六

芯片类

我在老师讲题之前就已经写完了这题，所以就没有在做修改，我以chipA作为基类，而非老师说的chip做基类，ABC为衍生类

chipA.h

#pragma once
#ifndef CHIPA_H
#define CHIPA_H
class chipA {
protected:
	int m, n;
public:
	chipA(int tempm, int tempn) :m(tempm), n(tempn) {}
	int add() {
		return m + n;
	}
	int minus() {
		return m - n;
	}
};
#endif

chipB.h

#pragma once
#ifndef CHIPB_H
#define CHIPB_H
#include"chipA.h"
class chipB :public chipA {
public:
	chipB(int tempm, int tempn):chipA(tempm,tempn){}
	int multiply() {
		return m * n;
	}
};
#endif // !CHIPB_H

chipC.h

#pragma once
#ifndef CHIPC_H
#define CHIPC_H
#include "chipA.h"
class chipC :public chipA {
public:
	chipC(int tempm, int tempn) :chipA(tempm, tempn) {}
	int divide() {
		return m / n;
	}
};
#endif // !CHIPC_H

main.cpp

// 芯片.cpp: 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include "chipA.h"
#include "chipB.h"
#include "chipC.h"
#include <iostream>
using namespace std;

int main()
{
	chipA temp1(3, 6);
	cout << "chipA测试：" << endl;
	cout << "加法：" << temp1.add() << endl << "减法：" << temp1.minus() << endl;
	chipB temp2(8, 4);
	cout << "chipB测试：" << endl;
	cout << "加法：" << temp2.add() << endl << "乘法：" << temp2.multiply() << endl;
	chipC temp3(10, 10);
	cout << "chipC测试：" << endl;
	cout << "加法：" << temp3.add() << endl << "除法：" << temp3.divide() << endl;
    return 0;
}

车类

vehicle.h

#pragma once

#define VEHICLE_H
class vehicle {

	int maxspeed, weight;
public:
	vehicle(int newmaxspeed,int newweight)
		:maxspeed(newmaxspeed),weight(newweight){}

#endif // !BICYCLE_H

motorcar

#pragma once
#ifndef MOTORCAR_H
#define MOTORCAR_H
#include"vehicle.h"
class motorcar :virtual public vehicle {

	motorcar(int newmaxspeed, int newweight, int newseatnum)
		:vehicle(newmaxspeed, newweight), seatnum(newseatnum) {}
	int seatnum;

		:bicycle(newmaxspeed, newweight, newheight),
		motorcar(newmaxspeed, newweight, newseatnum),
		vehicle(newmaxspeed,newweight) //由于无法调用更上层的虚基类，因此更上层的虚基类需要自己构造
		{}
};
#endif // !MOTORCYCLE_H

vehicle.cpp

#include"vehicle.h"
#include<iostream>
void vehicle::run() {
	std::cout << "run" << std::endl;
}
void vehicle::stop() {
	std::cout << "stop" << std::endl;
}

main.cpp

// 2.cpp: 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include "motorcycle.h"
#include <iostream>
using namespace std;

int main()
{
	motorcycle m(100, 200, 2, 2);
	m.run();
	m.stop();
    return 0;
}

出于方便，以上所有测试数据均已在main函数中提供好，没有要求输入
