亲，您好，很高兴为您解答：类rectangle中定义的两个变量width,length的区别具体如下：#includeusing namespace std;class Rectangle{protected:double length,width;public:Rectangle(double a,double b):length(a),width(b){}double area(){return length*width;}};class Rectangular:publiv clas 没有...
.创建一个Rectangle类,添加两个属性width和height。在Rectangle类中添加两个方法,计算矩形的周长和面积。 public class Rectangle{ private int width; 需要求3个长方柱的体积,请编写一个基于对象的程序。数据成员包括length长、width宽、height高。 #include<iostream> using namespace std; class A { 2023官网证券...
As we know that a rectangle is a 2D shape, so, it has only length and width but the rectangular shape in 3D like a rectangular box or a rectangular prism (cuboid) has all three dimensions: length, width, and height. So, we can say that extensions of rectangular shape in 3D contains ...
