Structures

While reading in the book "The complete C Reference". I got some notes!


Structures, Unions and Enumerations are declared/defined similar to each other

• struct tag{   type member_name;
     type member_name;   type member_name;
  } variable_list;
• union tag{   type member_name;
     type member_name;   type member_name;
  } variable_list;
• Enumeration tag{   enumeration list
  } variable_list;

Where, tag is optional, variable list is optional, but at least one of them must exist

• For bit fields, the bits runs from left to right or from right to left dependent on the machine
• typedef syntax:
  typedef type_name new_name;
