Unsigned keyword in C++

Question

Does the unsigned keyword default to a specific data type in C++? I am trying to write a function for a class for the prototype:

unsigned Rotate(unsigned object, int count) 

But I don't really get what unsigned means. Shouldn't it be like unsigned int or something?

Answer 1

From the link above:

Several of these types can be modified using the keywords signed, unsigned, short, and long. When one of these type modifiers is used by itself, a data type of int is assumed

This means that you can assume the author is using ints.

Answer 2

Integer Types:

short            -> signed short signed short unsigned short int              -> signed int signed int unsigned int signed           -> signed int unsigned         -> unsigned int long             -> signed long signed long unsigned long 

Be careful of char:

char  (is signed or unsigned depending on the implmentation) signed char unsigned char
