Example data type values

Basic types

      bool true, false
      char Enclosed in single quotes: 'a', 'A', 'x', '0', '('
      short Typical range: -32768 to 32767 
                   (e.g., not -32769 and not 32768)
      int Typical range: -2147483648 to 2147483647
      long Usually same range as int, but might be bigger
      float Maximum value usually about 1038
      fraction part is 23 bits (for a normalized float)
      223 = 8388608. So only about 6 digits can be assumed
      to be significant. 
      double Maximum value usually about 10307
      fraction part is 52 bits (for normalized) 252 =
      4503599627370496 (16 digits) So only about 15 digits can be
      assumed to be significant. 
   

Some class types

      string (No direct representation.) "Hello, World!", string("C++"). 

      The double quoted "Hello, World!" will automatically be
      converted to type string depending on how it is used. 

      The second example, string("C++"), explicitly requests conversion to type
      string. 

      istream cin is a predefined input stream
      associated by default with input typed on the keyboard. It is of
      type istream.
      ostream cout is a predefined output
      stream associated by default with output going to the
      screen or window (character and line based output).
