How is short int (or short) and int different in C? They have the same size and range. If they are essentially the same, what is the use of having two data types?

short int. signed short. signed short int. Short signed integer type. Capable of containing at least the [−32,767, +32,767] range.
In C++ (and C), short , short int , and int short are different names for the same type. This type is guaranteed to have a range of at least -32,767..
There is no difference.
short datatype is the variable range is more than byte but less than int and it also requires more memory than byte but less memory in comparison to int. The compiler automatically promotes the short variables to type int, if they are used in an expression and the value exceeds their range.
They may have the same size, but it is guaranteed that int is equal to or bigger than short int.

In theory/by the C standard, they could be of any size as long as 16 bit <= short <= int.
In the real world, this is how the sizes are implemented.
