Description
Creates two one-dimensional arrays, one with the
accepted applicants and another with the rejected
applicants. The entries in each array are in random order.
Creates a structure and assign each array to an element
of the structure.
Creates a structure with rejection codes for rejected
applicants. The
entries for all rejected applicants, and one of its values
does not match a valid code. The structure element
references use associative array notation in order to use
key names that contain spaces.
Sorts the accepted applicants alphabetically.
Displays a heading.
Loops through the accepted applicants and writes their
names. Curly brackets enhance clarity, although they are
not needed for a single statement loop.
Writes an additional line break at the end of the list of
accepted applicants.
Sorts

Loops through the rejected applicants.
Sets the applicant variable to the applicant name. This
makes the code clearer and enables you to easily
reference the
