Short name for type long long vs long long int, standard compatible?

Question

Most of the code I see uses shorthand types to declare a variable, for example

long long x; // long long int x
short y; // short int y

I was looking at the C ++ 11 standard (section 3.9.1), and the type is always declared completely, like long long int. I could not find references to abbreviated types. I am sure that abbreviations are standard, but they want to make sure that this is true. So my question is whether the code above meets the standard requirements.
