That is why we all love C. Best Job security in the world
for programmers.

There are always "issues" to fix.  You see, you yourself had to
work for few days on this one. If you had used Ada, or any  other
more strongly typed languages, then you'll be done early,
then the manager will have come in and saw you sitting
doing nothing becuase your program is done, and you'll be out
of work.

So, you should be very happy you are working on C.
