String problems

[chibicitiberiu]

Paul told you how to fix it. Reread his post.

In addition to what paul told you, you also make another mistake and that is controlling your file read loop with eof(). eof() is not for controlling loops, its for distinguishing errors from eof conditions. You probably notice that the file copied grows in size by a small amount.

It did grow with 1 byte, but not any more since it first writes and then reads, so it dumps the extra byte .
