面向?qū)ο蟪绦蛟O(shè)計(jì)編程 實(shí)驗(yàn) 上機(jī)

1、面向?qū)ο蟪绦蛟O(shè)計(jì)編程上機(jī)作業(yè)題目：（1） 調(diào)試構(gòu)造函數(shù)pen（）例題using system;using system.collections.generic;using system.text;namespace consoleapplication2 class pen public string color; private int price; public pen() color=black; price=5; public void setprice(int newprice) price=newprice; public int getprice() return price;

2、public void setcolor(string newcolor) color=newcolor; public string getcolor() return color; class test public static void main()pen mypen=new pen() ;console.writeline(the price is 0,mypen.getprice();console.writeline(the color is 0,mypen.color); （2） 調(diào)試構(gòu)造函數(shù)重載pen（）例題using system;class pen public stri

3、ng color; private int price; public pen() color = black; price = 5; public pen(string newcolor, int newprice) color = newcolor; price = newprice; public void setprice(int newprice) price = newprice; public void setprice() price = 5; public int getprice() return price; public void setcolor(string new

4、color) color = newcolor; public string getcolor() return color; class test public static void main() pen mypen = new pen(); pen hispen = new pen(green, 8); console.writeline(the price is 0, mypen.getprice(); console.writeline(the color is 0, mypen.color); console.writeline(the price is 0, hispen.get

5、price(); console.writeline(the color is 0, hispen.getcolor(); hispen.setprice(); console.writeline(the price is 0, hispen.getprice(); （3）使用重載方法求5和5.65的平方。using system;using system.collections.generic;using system.text;namespace consoleapplication8 class program public class app public int app1(int x

6、) return x * x; public double app1(double y) return y * y; static void main(string args) app x = new app(); 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）將運(yùn)算符+和- -進(jìn)行重載，使之可對(duì)字符型數(shù)據(jù)進(jìn)行運(yùn)算，即：對(duì)一個(gè)字符型變量a，當(dāng)a=l時(shí)a+(或+a)的值為m, a- -(或- -a)的值為kusing system;using system.collection

7、s.generic;using system.text;namespace consoleapplication6 public class chartest private char ch; public chartest() this.ch = ; public chartest(char val) this.ch = val; public char c get return this.ch; set this.ch = value; static public chartest operator +(chartest orig) chartest result = new charte

8、st(); result.ch = (char)(orig.ch + 1); return result; static public chartest operator -(chartest orig) chartest result = new chartest(); result.ch = (char)(orig.ch - 1); return result; public class overloadapp public static void main() chartest a = new chartest(l); chartest b = new chartest(l); cons

9、ole.writeline(original value is :0,1, a.c, b.c); a = +a; b = -b; console.writeline(current value is :0.1, a.c, b.c); a = +a; b = -b; console.writeline(final value is:0,1, a.c, b.c); （5）編寫一個(gè)控制臺(tái)程序，完成下列功能并輸出結(jié)果：創(chuàng)建一個(gè)類test1，用無(wú)參數(shù)的構(gòu)造函數(shù)輸出該類的類名；增加一個(gè)重載的構(gòu)造函數(shù)，帶有一個(gè)string類型的參數(shù)，在此構(gòu)造函數(shù)中將傳遞的字符串打印出來(lái)；在main方法中創(chuàng)建屬于test1類

10、的一個(gè)對(duì)象，不傳遞參數(shù)；在main方法中創(chuàng)建屬于test1類的另一個(gè)對(duì)象，傳遞一個(gè)字符串“this is a string”；using system;using system.collections.generic;using system.text;namespace consoleapplication8 class program class test1 public string test; public test1() test = test1; public test1(string s) test = s; static void main(string args) strin

11、g x = this is a string; test1 app1 = new test1(); test1 app2 = new test1(x); console.writeline(0, app1.test); console.writeline(0, app2.test); （6）編寫一個(gè)控制臺(tái)程序，完成下列功能并輸出結(jié)果：創(chuàng)建一個(gè)類a，在a中編寫一個(gè)可以被重寫的帶int類型參數(shù)的方法mymethod,并在該方法中輸出傳遞的整型值加10后的結(jié)果；再創(chuàng)建一個(gè)類b，使其繼承自類a，然后重寫a中的mymethod方法,將a中接收的整型值加50，并輸出結(jié)果； 在main方法中分別創(chuàng)建類a和類

12、b的對(duì)象，并分別調(diào)用mymethod方法；using system;class classa public static int mymethod(int i) i=i+10; return i;class classb:classapublic static int mymethod(int i)i=i+50;return i;class testpublic static void main() classa a=new classa(); classb b=new classb(); console.writeline(請(qǐng)輸入一個(gè)數(shù)：); string s=console.readlin

13、e(); int x=int32.parse(s); console.writeline(調(diào)用a類方法：0, classa.mymethod(x); console.writeline(調(diào)用b類方法：0, classb.mymethod(x); （7）利用委托實(shí)現(xiàn)：當(dāng)用戶輸入一個(gè)字符1時(shí)，調(diào)用兩個(gè)整數(shù)相加的方法，計(jì)算兩整數(shù)之和；當(dāng)用戶輸入一個(gè)字符2時(shí)，調(diào)用兩個(gè)整數(shù)相減的方法，計(jì)算兩整數(shù)之差。using system;class appdelegate int process(int a,int b); public static int add(int a,int b) return a+b; public static int sub(int a,int b) return a-b;static void main() string s,s1,s2; process pro; console.writeline(請(qǐng)輸入一個(gè)數(shù)：); s1=console.readline(); int a=int32.parse(s1); console.wr
