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????? The exe that you download itself won't be able to sent to...

you can use gets to get one line and then tokenize it

ex :
[c]char line[100];
gets (line);

for (int i=0;line!='\0';i++)
if (line==' ') {
//if it's space do something....
}
else {
// do something else....
}
[/c]

another way is to use strtok.

just curious, are you trying to solve 494??
