What is the difference between "short int" and "short" in c?

Question

What is the difference between declaring variables as short int and short? In the gcc compiler, short takes 2 bytes (checked with sizeof (short)), and short int also gives 2 bytes size. Are both the same - different? In this case, these ads will be useful?

Thanks in advance

Answer 1

short not suitable for short int , they are equivalent in any C compiler.

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

Answer 2

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

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

The same goes for long
