学生实验报告

一、实验综述

1、实验目的及要求

完成以下上机题目

1. Given a Rectangle class, which has Width and Height attributes and the following behaviors:

(1) Init(): to initialize the Width and Height

(2) SetWidth(): to set Width

(3) SetHeight(): to set Height

(4) GetWidth(): to get Width

(5) GetHeight(): to get Height

(6) Area(): to calculate the area of the rectangle

(7) DispInfo(): to show the information of the rectangle such as Width, Height and area.

Please analyze and design the class based on the above requirements.

2. Design a class Circle, which can be used to calculate the area and circumference of a circle. The radius is set when initializing an object. Please give a main function to call the class.

3. Design a Rectangle class with two attributes, Width and Height and to satisfy the following requirements. When the object is initialized by two arguments, which represent Width and Height respectively. But, when the object is initialized by only one argument, which means the rectangle is a square. There is a member function to show the area of the Rectangle in the class. Please also give a main function to call the class.
