I'm not smart enough to suggest a fix here, I'm just pointing out that this article is not the PdV from the well known article.

But I can spot when code is doing exactly what the cited article says not to do,

This line is the "validate" in the expression "parse, don't validate":

  if (theEmail.error != PARSE_OK)

You might like it, but that's not my business. Maybe this C article should have been "parse, then validate".

You'd be better off reading the original: https://lexi-lambda.github.io/blog/2019/11/05/parse-don-t-va...
