I'm using C language. I tried to looked back in previous post (waaay back), apparently someone already posted AC source code here, he use some formula to indicated terminating condition. I haven't tried that, but in my source code everytime I print I increment the counter and I check if counter==inp...

any trick here??

I'll send my source code or post it here if it's
necessary, although I prefer sending my source
code to anyone who wants to help

Here's a thought by mailing list that I joined: how about uploading exe on to some helping site so that anyone that didn't get Ac can compare the exe themself. beside..., downloading exe is not cheating like downloading source code right?????

ex :
[c]char line[100];

}
else {
// do something else....
}
[/c]

another way is to use strtok.
