Other Topics (before pointers)

• Bit Fields ( for now too detailed )

• Unions – save space, but hard to understand, ignore for now.

• Enumerations

  • pretty good idea for named arrangements
  • e.g. enum work_days {mon,tue,wed,thu,fri};
  • more readable and useful
  • If you use numbers for work_days, you may assign a value of 1 for mon, 2 for tue, etc. BUT what happens if you assign 19!
