利用抽象类实现电脑组装案例

面向抽象类编程

#define _CRT_SECURE_NO_WARNINGS
#include<iostream>


using namespace std;

/*===========start抽象层============*/

//CPU抽象类
class CPU  {
public:
	virtual void caculate() = 0;
};

//显卡抽象类
class Card {
public:
	virtual void display() = 0;
};


//内存条抽象类
class Memory {
public:
	virtual void storage() = 0;
};


class Computer {
public:
	Computer(CPU *tcpu1, Card * tcard, Memory * tmemory) :cpu1(tcpu1), card(tcard), memory(tmemory) {};
	void print() {
		cpu1->caculate();
		card->display();
		memory->storage();
		cout << "=========================" << endl;
	}
private:
	CPU *cpu1;
	Card * card;
	Memory * memory;


};

/*===========start实现层============*/

//Intel
//IntelCPU
class IntelCpu :public CPU {
public:
	virtual void caculate() {
		cout << "IntelCPU" << endl;
	}
};

//Intel显卡

//Intel内存条

};


//NIVDE显卡
class NVIDIACard : public Card {

//Kingston内存条

/*===========业务逻辑层============*/


int main(char *argv[], int argc)
{
	//组装一台纯Intel的电脑
	Computer p1(new IntelCpu,new IntelCard,new IntelMemory);
	p1.print();


	//组装一台IntelCpu,NVIDIACard,KingstonMemory的电脑
	Computer p2(new IntelCpu, new NVIDIACard, new KingstonMemory);
	p2.print();


	return 0;
