Ah ha! Yes, I did check the docs but I think I just glanced over that portion. Be more careful next time. The < is a less than sign but it seems it doesn’t render correctly on Lemmy.
Comment on Why does isalpha() fail to identify an alphabetic character?

isalpha documentation:
Return value Non-zero value if the character is an alphabetic character, zero otherwise.
You should be either checking for not equal to 0 instead of true, as its not necessarily guaranteed to be 1 ~= true
Also make sure that your loop condition is < and not <
For more information, make sure to check the documentation for the standard library functions

Never, ever write “== true” or “== false” unless it’s absolutely necessary.

I would drop the “== true” entirely. C will evaluate any nonzero int as true in an “if” statement.

Good point!
