用vs编写选择性别的简易程序

请参考如下代码

using System

using System.Collections.Generic

using System.Linq

using System.Text

namespace SimpleFictory

{

public abstract class OperationBase

{

private double _num = 0

private double _number = 0

public double Num

{

get { return _num}

set { _num = value}

}

public double Number

{

get { return _number}

set { _number = value}

}

public abstract double Amount()

}

class Add : OperationBase

{

public override double Amount()

{

double result = 0

result = Num + Number

return result

}

}

class Sub : OperationBase

{

public override double Amount()

{

double result = 0

result = Num - Number

return result

}

}

class Minus : OperationBase

{

public override double Amount()

{

double result = 0

result = Num * Number

return result

}

}

class Div : OperationBase

{

public override double Amount()

{

double result = 0

if (Number == 0)

throw new Exception("除数不能为0。")

result = Num / Number

return result

}

}

public abstract class OperationFactory

{

public static OperationBase createOperate(string operate)

{

OperationBase oper = null

switch (operate)

{

case "+":

oper = new Add()

break

case "-":

oper = new Sub()

break

case "*":

oper = new Minus()

break

case "/":

oper = new Div()

break

}

return oper

}

}

class Program

{

static void Main(string[] args)

{

OperationBase oper

oper = OperationFactory.createOperate("+")//可根据要求更改运算符,仅以加法为例。

oper.Num = 1

oper.Number = 2

double result = oper.Amount()

Console.WriteLine("结果是{0}", result)

Console.ReadKey()

}

}

}

qq小程序soso交友更改性别：

1、先在qq小程序里面，找到soso，点击打开程序。

2、进入到soso后，点击右下角的我的。

3、在我的界面，能看到右上角的编辑资料选项，点击打开。

4、然后能看到我的性别修改选项，选择性别。

5、重新选择完成后，滑动屏幕到底部，点击保存。

6、保存成功后，返回到我的界面，能看到性别已经修改成功。

public class Example{

    public static void main(String[] args){

        Scanner input=new Scanner(System.in)

        //显示菜单

        System.out.println("请选择性别：1-男  2-女")

        try{

            int sex=input.nextInt()

            if(sex==1){

                System.out.println("您选择了男！")

            }else if(sex==2){

                 System.out.println("您选择了女！")

            }else{

                 System.out.println("只能选择1和2！")

            }

        }catch(Exception e){

            System.out.println("菜单选择有误，只能输入数字："+e.getMessage())

        }

    }

}
