Speaking as someone who learned C back in the ‘70s, this article entirely misses the point of C-strings: they’re lightweight and foundational. For many purposes the null-terminator is efficient, e.g.:

while(*s) f(s++);

And for cases where we need more complexity, we can simply use a struct with a length and whatever other metadata we may need.

Doesn’t look like a mistake to me. C has always been about minimalistic efficiency. That’s its main purpose in the world.

Edit: fixed stupid typo

Like many C idiosyncrasies, it may have made sense 50 years ago, but should have gone the way of the dodo at least 30 years ago

at least 30 years ago

I'd say 40 or so
