need debugging questions....

hi every one...
i need a few debugging questions in C to practice...
i googled for it but couldnt find anything useful..
can any one tell me where i can find them...
if any one has any e books.. mail it to <<snipped>>

Thank You.

Just hang around on forums for a while, and wait for the next "why doesn't this code work" questions.

Or just look at past posts and avoid scrolling down to the "answers".

hey... thank u for replying...
but i need more questions....
can i get any material or books or url???

Huh?
There's a decade of problems and solutions on this board, what exactly do you want?

i have to prepare for a competition.....
so i was in search of them...
i wanted a few for practice....
i know many sites where there are algorithm design questions... like spoj, topcoder.....
but i dont know any site which has debugging questions...
