<code c>
int feof(FILE *stream);
</code>
checks that are applied to a stream or data or the end-of-file indicator is set.\\
Used to determine if the end of the file (stream) specified, has been reached. When a file is being read sequentially one line, or one piece of data at a time (by means of a loop, say), this is the function you check every iteration, to see if the end of the file has come.\\
Returns non-zero if end-of-file indicator is set for stream stream.
