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 ob         


        

Answer 1

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
