Like   C,   C++   does   not   have   built-in   input/output   capability.   All   C++   compilers,   however,   come   bundled   with   a   systematic,   object-oriented   I/O   package,   known   as   the   iostream   classes.   The   “stream”   is   the   central   concept   of   the   iostream   classes.   You   can   think   of   a   stream   object   as   a   “smart   file”   that   acts   as   a   source   and   destination   for   bytes.   A   stream’s   characteristics   are   determined   by   its   class   and   by   customized   insertion   and   extraction   operators.  
   
  Through   device   drivers,   the   disk   operating   system   deals   with   the   keyboard,   screen,   printer,   and   communication   ports   as   extended   files.   The   iostream   classes   interact   with   these   extended   files.   Built-in   classes   support   reading   from   and   writing   to   memory   with   syntax   identical   to   that   for   disk   I/O,   which   makes   it   easy   to   derive   stream   classes.

流是一种存储组件及其有关属性值的信息的方式。组件的特征之一就是必须能进行流操作，Top
