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

Yes, it means unsigned int. It used to be that if you didn't specify a data type in C there were many places where it just assumed int. This was try, for example, of function return types.

This wart has mostly been eradicated, but you are encountering its last vestiges here. IMHO, the code should be fixed to say unsigned int to avoid just the sort of confusion you are experiencing.
