[SOLVED] CS计算机代考程序代写 #pragma once

#pragma once
#include “CSquare.h”
class CSquare;

class CRectangle
{
private:
int width;
int height;

public:
int area() const
{
return width * height;
}

void setValues(int w, int h);

// Non member function declared as friend to access private members of CRectangle
friend CRectangle dupAndDouble(CRectangle other);

void convert(CSquare sqr);
};
