如图，如何实现这串代码，定义并实现一个矩形类Crectangle

Answer 1

#include <iostream>
using namespace std;
 
class Rectangle
{
public:
    Rectangle(double x, double y)
    {
        length = x;
        wide = y;
    }
    Rectangle()
    {
 
    }
    double area(double length, double wide)
    {
        return length * wide;
    }
    void display()
    {
        cout << "length=" << length << " wide=" << wide << " are=" << area(length, wide) << endl;
 
    }
    void setlength(double x)//设置
    {
        length = x;
    }
    void setwide(double y)//设置
    {
        wide = y;
    }
    double getlength()//获取
    {
        return length;
    }
    double getwide()//获取
    {
        return wide;
    }
private:
    double length;
    double wide;
 
};
