[YTU]_2916(Shape系列-2)

Description

小聪不喜欢小强的Shape类，声称用Shape类做出的形状不真实，于是小聪创建了Rectangle类，并且决定用该类做两个矩形出来，送给好朋友小亮。Rectangle类有整型的数据成员color（小强的Shape类中的color可以继续使用，无需新定义），浮点型的数据成员width和height，求面积的成员函数area()。但是小聪没有为Rectangle类写构造函数和成员函数，请帮助小聪完成Rectangle类。

小强写的文件头和Shape类：

#include<iostream>

using namespace std;

class Shape

{

public:

Shape();

Shape(int c);

int getcolor();

double area();

protected:

int color;

};

Shape::Shape()
{

color=0;

}
Shape::Shape(int c)
{

color=c;

}
int Shape::getcolor()
{
        return color;

}
double Shape::area()
{
       return 10000;
}

小聪的测试函数：

int main()

{

Rectangle rr=Rectangle(1,2,3);

cout<<"Rectangle color:"<<rr.getcolor()<<endl

<<"Rectangle width:"<<rr.getwidth()<<endl

<<"Rectangle height:"<<rr.getheight()<<endl

<<"Rectangle area:"<<rr.area()<<endl

<<"Rectangle price:"<<rr.price()<<endl;

return 0;

}

提示：不用提交全部程序，只提交补充部分。

Input

无

Output

输出小聪创建的矩形的相关数据。
