for int (i= 65; i<=90;i++ )
	{
         char drive_ID = i ;
	 int drive_type = GetDriveType(drive_ID);
        }

chars are like all other numbers so you can assign numeric literals to them:
char c = 65; is the same as char c = 'A';

Yes you can chiwing.

Except on non-ASCII systems... (like old IBM mainframes and the like -- which are still in significant use).

I don't suspect Windows actually runs on any of them though...
