Wait, what? Where’s your error checking? What if your printf fails?
Actually that’s one of the things I like least about C. It leaves all error
checking up to the programmer instead of having even a minimal handler for
errors not otherwise caught.

    The whole context of 'C' was that COMPETENT PROGRAMMERS
   existed and could/would assess error conditions as THEY
   chose to do so.

The reality of C is that even competent programmers find this
very difficult and often make elementary mistakes with potentially
serious consequences, as we see on a daily basis.
