How do I write a short literal in C++?

Yeah, it’s not strictly a short literal, more of a casted-int, but the behaviour is the same and I think there isn’t a direct way of doing it.

That’s what I’ve been doing because I couldn’t find anything about it. I would guess that the compiler would be smart enough to compile this as if it’s a short literal (i.e. it wouldn’t actually allocate an int and then cast it every time).

The following illustrates how much you should worry about this:

a = 2L;
b = 2.0;
c = (short)2;
d = '\2';

Compile -> disassemble ->

movl    $2, _a
movl    $2, _b
movl    $2, _c
movl    $2, _d
