Define some Important Point for bit fields with structures?

  • Only n lower bits will be assigned to an n bit number thus type cannot take values larger than 15 (4 bits long)
  • Bit fields are forever converted to integer type for computation.
  • You are permitted to mix ``normal'' types with bit fields.
  • The unsigned definition is important-ensures that no bits are used as a flag.
