第三次作业：0~10的随机四则运算

标签：

    虽然放假前有让同宿舍的女生把软件给我弄到U盘里，但是结果回家安装不上，所以就只是在记事本里打了代码。结果能不能运行其实我并不知道，只是把一些代码发上来。

    下面就是我的代码

 namespace   add
   {
       class   Program
       {
          static    void  Main(string[] args)
           {
               int    right=0;
               int    wrong=0;
               do
                {
                    Random  sj=new Random();
                    int  x=sj.Next(0,11);
                    int  y=sj.Next(1,3);
                    Console.WriteLine("请选择一项进行运算+,-,*,/;或者按Enter后输入P结束进程");
                    string i=Convert.ToString(Console.ReadLine());
                    if(i == "+")
                    {
                        Console.WriteLine("{0}+{1}=",x,y);
                        int z=Conver.ToInt32(Console.ReadLine());
                        if(z == x + y)
                        {
                        right++;
                        }
                        else
                        {
                           Console.WriteLine("抱歉,回答错误！");
                           wrong++;
                        }
                     }
                     else
                      if(i == "-")
                      {
                         Console.WriteLine("{0}-{1}=",x,y);
                          int z=Conver.ToInt32(Console.ReadLine());
                          int(z ==x - y)
                          {
                             right++;
                           }
                           else
                          {
                             Console.WriteLine("抱歉，回答错误！");
                             wrong++;
                           }
                        }
                        else
                         if(i == "*")
                         {
                            Console.WriteLine("{0}*{1}=",x,y);
                            int z=Conver.ToInt32(Console.ReadLine());
                            if(z == x * y)
                            {
                               right++;
                            }
                            else
                            {
                               Console.WriteLine("抱歉，回答错误！");
                               wrong++;
                             }
                           }
                           else
                           if(i == "/")
                           {
                              Console.WriteLine("{0}/{1}=",x,y);
                               int z = Conver.ToInt32(Console.ReadLine());
                               if(z == x/y)
                                {
                                   right++;
                                 }
                                 else
                                 {
                                   Console.WriteLine("抱歉，回答错误！");
                                   wrong++;
                                   }
                                }
                          }
                          while (Console.ReadLine()! = "P");
                           Console.WriteLine("您答了{0}题,正确:{1},错误:{2}",right+wrong,right,wrong);
                           Console.ReadLine();
                    }
               }
       }

     这个就是我的代码了，我明天回学校会先运行的，如果不成功，我会再改进。
