雨刷类头文件

代理类头文件

#include "Lever.h"
#include "Dial.h"
#include "Wiper.h"

class Agent{

代理类源文件

#include "Agent.h"

	int wiperSpeed = 0;
	
	switch(leverPosition)
	{
	case 1:

	case 2:

	}

	this->objw.setWiperSpeed(wiperSpeed);
}

void Agent::show()
{
	cout<<"Now the Lever‘s position is: ["<<this->objl.getPosition()<<"]"<<endl;
	cout<<"The Dial‘s position is: ["<<this->objd.getPosition()<<"]"<<endl;
	cout<<"The Wiper‘s speed is: ["<<this->objw.getWiperSpeed()<<"]"<<endl<<endl;
}

主函数源文件

#include <iostream.h>
#include <stdlib.h>
#include "Agent.h"

void menu()
{
	cout<<"============== 1 Lever up ================"<<endl; 
	cout<<"============== 2 Lever down =============="<<endl; 
	cout<<"============== 3 Dial up ================="<<endl; 
	cout<<"============== 4 Dial down ==============="<<endl; 
	cout<<"============== 0 Exit ===================="<<endl; 
	cout<<endl;
	cout<<"Please input your choice:"<<endl;
}

void main()
{
	Agent obja;
	int input;
	menu();
	cin>>input;
	while(1)
	{
		switch(input)
		{
		case 1:
			obja.upLeverPosition();
			break;
		case 2:
			obja.downLeverPosition();
			break;
		case 3:
			obja.upDialPosition();
			break;
		case 4:
			obja.downDialPosition();
			break;
		case 0:
			exit(0);
		}
		obja.judgeWiperSpeed();
		obja.show();
		menu();
		cin>>input;
	}

}

大家好好看下这个代码，把类之间的关系搞清楚，尤其是类的封装性、类之间的低耦合性以及类的内聚性对面向对象设计的影响。然后
再去完善一下第七次关于继承的作业。
