expected 'while' before '}' token error

i'm sorry if this question is shouldn't be asked because maybe it's too easy(i guess), but i do really don't know how to solve this. i've tried to put the 'while' before the last '}' (which i know it won't solve the problem. just a little bit desperate though).

and i've looking for answers in many sources including this forum. but i'm not founding the answer yet. so please, teach me master! />


okay, here's the code pieces where the error notification comes up:

(for language reason i can't put the whole code or should i?)
it's a driver file for a tree data structure

      		     		system ("clear");
      		}
		{
      		while(pil!=5);
		
		}
	}
     }
   } //it says that the expected while before '}' should be here
}

thanks in advance, and i'm sorry for my bad english
