1、面向对象程序设计编程上机作业题目：（1）调试构造函数Pen（）例题usingSystem;usingSystem.Collections.Generic;usingSystem.Text;namespaceConsoleApplication2{classPen{publicstringColor;privateintPrice;publicPen(){Color="BLACK";Price=5;}publicvoidSetPrice(intnewPrice){Price=newPrice;}publicintGetPrice()

2、{returnPrice;}publicvoidSetColor(stringnewColor){Color=newColor;}publicstringGetColor(){returnColor;}}classTest{publicstaticvoidMain(){PenmyPen=newPen();Console.WriteLine("Thepriceis{0}",myPen.GetPrice());Console.WriteLine("TheColoris{0}",myPen.Color);}}}（2）调试构造函数重载Pe

3、n（）例题usingSystem;classPen{publicstringColor;privateintPrice;publicPen(){Color="BLACK";Price=5;}publicPen(stringnewColor,intnewPrice){Color=newColor;Price=newPrice;}publicvoidSetPrice(intnewPrice){Price=newPrice;}publicvoidSetPrice(){Price=5;}publicintGetPrice(){return

4、Price;}publicvoidSetColor(stringnewColor){Color=newColor;}publicstringGetColor(){returnColor;}}classTest{publicstaticvoidMain(){PenmyPen=newPen();PenhisPen=newPen("GREEN",8);Console.WriteLine("Thepriceis{0}",myPen.GetPrice());Console.WriteLine("TheColoris{0}",myPen.Co

5、lor);Console.WriteLine("Thepriceis{0}",hisPen.GetPrice());Console.WriteLine("TheColoris{0}",hisPen.GetColor());hisPen.SetPrice();Console.WriteLine("Thepriceis{0}",hisPen.GetPrice());}}（3）使用重载方法求5和5.65的平方。usingSystem;usingSystem.Collections.Generic;usingSystem.Text;nam

6、espaceConsoleApplication8{classProgram{publicclassapp{publicintapp1(intx){returnx*x;}publicdoubleapp1(doubley){returny*y;}}staticvoidMain(string[]args){appx=newapp();Console.WriteLine("5的平方是{0}",x.app1(5));Console.WriteLine("5.65的平方是{0}",x.app1(5.65));}}}（4）将运算符++和--进

7、行重载，使之可对字符型数据进行运算，即：对一个字符型变量a，当a=’L’时a++(或++a)的值为’M’,a--(或--a)的值为’K’usingSystem;usingSystem.Collections.Generic;usingSystem.Text;namespaceConsoleApplication6{publicclasscharTest{privatecharch;publiccharTest(){this.ch='';}publiccharTest(charval){this.ch=val;}publicchar

8、c{get{returnthis.ch;}set{this.ch=value;}}staticpubliccharTestoperator++(charTestorig){charTestResult=newcharTest();Result.ch
