What the difference between unsigned short int and unsigned int or unsigned short?

Question

According to: http://en.wikipedia.org/wiki/C_data_types you can use unsigned short type or unsigned short int type. But what the difference between them? I know what is unsigned short and I know what is unsigned int but what does unsigned short int mean? Is it short or is it int?

Answer 1

unsigned short和unsigned short int指的是完全相同的数据类型，并且可以互换。

Answer 2

"but what does unsigned short int mean? Is it short or is it int ?"

There's no difference. It's an unsigned short , actually the int keyword is optional for short or long declarations. The unsigned keyword may applied to all of these type declarations, and makes them just unsigned .
