求大神帮忙啊，一道c++作业

CRectangle r;
int a=1,b=2,c=4,d=3;
char i='0';
r.setPoint(a,b);
r.showRectangle(c,d);
while(i!='5')
{
cout<<"按1移动矩形:"< cout<<"按3返回左上角坐标值:"< i=getch();
if(i=='1')
{
r.Move(&a,&b);
r.showRectangle(c,d);
}
if(i=='2')
{
r.Size(&c,&d);
r.showRectangle(c,d);
}
if(i=='3')
r.Where();
if(i=='4')
r.Area();
}
}
这个是我自己做的矩形类，你自己拿去删除一些修改一下，有什么问题再问我吧，顺便求采纳
