When i use "while((sym=getchar())!=EOF)", i get WA#1
When i use "while((scanf("%c",&sym)>0)", without changing the rest of the program, i don't get WA#1, but scanf is very slow! I get TL#2.
"while(!feof(stdin))" also give me WA#1.
How can i find the end of data?!

Tell me, please! How to do this? In FAQ written "while ((c = getchar()) != EOF)", but it doesn't work!!
