short is short for short int, they are equivalent in any C compiler.

The same for long int vs long, long long int vs long long.

Does anyone know the history behind this? Why it was included at all? – searchengine27 Aug 21 '20 at 18:09

short, short int, signed short int, and signed short are all same data-types.

So sizeof(short) == sizeof(short int)

The same goes for long

You forget `auto signed short int` :P – David Ranieri Feb 04 '15 at 10:53

@AlterMann: `auto` is a storage class specifier, like `static`, `extern`, `register`, etc. It doesn't specify a type. – Dietrich Epp Feb 04 '15 at 11:25
@DietrichEpp, I mean `auto signed short int x;` = `short x;`, but it's a joke ... – David Ranieri Feb 04 '15 at 11:30
