1、第一套设计并测试一个矩形类（Rectangle），属性为矩形的左上与右下角的坐标，矩形水平放置。操作为计算矩形周长与面积。输出见样张-------------------------------------------------------*/#include#includeusingnamespacestd;/**********Program**********/classRectangle{private:doubleleft,top,right,bottom,area

2、,perimeter;public:Rectangle(doublel=0,doublet=0,doubler=0,doubleb=0);~Rectangle(){};voidAssign(doublel,doublet,doubler,doubleb);voidShow();doublegetLeft(){returnleft;}doublegetTop(){returntop;}doublegetRight(){returnright;}doublegetBottom(){returnbottom;}dou
