C++编程 设计一个类用来求两个矩形的周长之和及面积之和。

这非得用类吗?其实就是一个函数.
#include <iostream>
using namespace std;

class CArea
{
public:
void area(int width1, int height1, int width2, int height2);
};

void CArea::area(int width1, int height1, int width2, int height2)
{
cout<<"周长和是:"<<(width1+height1+width2+height2)*2<<endl;
cout<<"面积和是:"<<width1*height1+width2*height2<<endl;
}

void main()
{
CArea myarea;
myarea.area(3,3,3,3);
}
