Eight times in a row i'm given "compilation error"! The following online C compiler: http://www.delorie.com/djgpp/compile/ says everything it's okay. No errors/warnings there...

i think the compiler of this online judge still using old C.HINT,maybe u use comments notation of C++ ,this is , //.
and declare it first before u use it . i sugest u use C++ compiler to submit the answer ,perhaps it will work.

I lick ass.I shit down
