【C#】上机实验五

原作者: [db:作者] 来自: [db:来源] 收藏 邀请
1、设计一个控制台应用程序,定义一个MyPoint类,该类能表示二维平面空间的点,完成点类及运算符重载等相关功能。具体要求如下:
(1)MyPoint类中定义2个私有字段x和y及相应的构造函数。
(2)MyPoint类中重载ToString方法输出坐标x和y的值。
(3)MyPoint类中重载一元运算符“-”。
(4)MyPoint类中重载二元运算符“+”和“-”。
(5)MyPoint类中重载二元运算符“>”和“<”。
(6)MyPoint类中重载二元运算符“==”和“!=”。
(7)在Main方法中测试上述运算符。

(3)Box类中重载一元运算符“-”。
(4)Box类中重载二元运算符“+”和“-”。
(5)Box类中重载二元运算符“>”和“<”。
(6)Box类中重载二元运算符“==”和“!=”。
