Interesting, I didn't fully realise that. That it's arbitrary is annoying, I clearly had tried to rationalise it to myself! Thanks for the comments, will get around to amending

Hi, great article. Regarding char, I'd remark that getchar() etc return int so it can return -1 for EOF or error.

I'm pretty sure this implies int as a declaration is always signed, but tbh I'm not completely sure!

int, as all other integer types except char, is indeed signed by default.

Aside: signedness semantics of char is implementation-defined. However, the type char itself is always distinct from both signed char and unsigned char.
