c++刷新不了缓冲区 RRS feed

  • 问题

  • #include <iostream>

    #include <iomanip>

    using namespace std;

    const char *ptr_dec[]={"●"};

    int main()
    {
        M:system("title The Tank Fighting");

     system("mode con cols=95 lines=45");

     system("color 4D");

     int sentry=14;

     for(int Enter_val=0;Enter_val!=sentry;Enter_val++)

     {
      
      cout<<endl;

     }

     cout<<setw(37)<<"     "<<"please the mode of game"<<endl<<endl;

     cout<<setw(37)<<"    "<<*ptr_dec<<" "<<"1.one man to play"<<endl<<endl;

     cout<<setw(37)<<"    "<<"   "<<"2.two men to play "<<endl<<endl;

        /*M:*/int Select_mode;

     fflush(stdin);

     cin>>Select_mode;


     if(Select_mode==1||Select_mode==2)

     {

      if(Select_mode==1)
      {
       fflush(stdin);                                //The opeater use refurbish Buffer.

       cout<<"please input anything to Select checkpoints"<<endl;

       int ch;

       ch=getchar();

       system("cls");
      }

      else
      {

       system("cls");

       int sentry=14;

       for(int Enter_val=0;Enter_val!=sentry;Enter_val++)

       {
      
        cout<<endl;

       }


       cout<<setw(37)<<"     "<<"please the mode of game"<<endl<<endl;

       cout<<setw(37)<<"                                        "<<"1.one man to play"<<endl<<endl;

       cout<<setw(37)<<"    "<<*ptr_dec<<" "<<"2.two men to play "<<endl<<endl;

       cout<<""<<endl;

       fflush(stdin);

       int ch;

       ch=getchar();

       system("cls");
      }

     }

     

     else

     {
      

      fflush(stdin);         

      cout<<"you opeator is inlegal ,please input one or two"<<endl;//就是这句

       goto M;

      
     }

    当我输入不是1和2时,就会无限输出cout的语句我明明刷新的缓冲区怎么没用

     
     return 0;
    }
