You do *not* have to "gets()" nasty. I sometimes use bubble sort

There isn't any good reason to use it.

There's one: simplicity. You don't need to handle the
newlines yourself.

Discarding the last character in a buffer read with fgets() is hardly a
burden.

A good programmer is a lazy programmer.

That's why they wrap fgets() in a function that checks for error and
removes the newline!

For a five-line throw-away program, that would be overkill.

When the entire user base is one person, it might be feasible
to shift the burden of safety to the user. The programmer needs
only to forewarn the user of the consequences of exceeding the
prescribed line length. If the user ignores this advice, then
the responsibility lies with the user, not the programmer.

So you'd rather add code to warn the user than remove a newline.

In Charles Richmond's case, the user is /also/ the
programmer, so there is no need to add code.
