4. Enumerations

• Keyword enum

• Examples:

  
      enum Suit { CLUB, DIAMOND, HEART, SPADE };
      Suit s; // enum keyword here not required
      s = CLUB; // of course
      s = (Suit) 1; // Ok, not recommended
      s = 1; // ERROR
      switch ( s ) { //...
  
      enum PrintFlags {
          COLOR = 1,
          LANDSCAPE = 2,
          TWOSIDE = 4
      };
