How can i fix it

Heres the code:Not finished tho)

   		else

         }
         break;

      case 2:

          clrscr()

         cout<<"Enter The Input File(C:\example.txt): ";gets(input_file);fflush(stdin);
         cout<<input_file<<endl;
        
   }

}

Also any suggestions on how to improve the code would cool

Thanks alot
