   This program demonstrates how structures ('struct') can be
    used to group together related pieces of data.  Vectors
    and matrices can serve that purpose if all the data are of
    the same type.  Structures can be used to create a new
    'type' that encompasses variables of different types.

   Structures are nearly identical to classes (see the class
    sample programs), with the exception that all of the data
    in a structure is public--none of it is private.  With
    structures it is possible to have uninitialized data, as
    well as data that have not been initialized properly.  This
    is because users have direct access to the data in a
    structure, which means that invalid values can be assigned
    to the members of a structure if one is not careful.

   Three structures are set up below.  They simulate a school
    database of student information.  Notice that a structure
    can contain another structure.  Note, also, that a semicolon
    must be placed after the closing brace of each structure.
