This is correct as written. The variable 'x' starts out initialized
to zero.  Thus on the first line it will get set to the length of
that line. As each subsequent line is read, if x is less than the
length of the current line, it's updated. By the end, it contains the
length of the longest line in the input.

Thanks,
