c++刷新不了缓冲区

Question

#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;
}
