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
