In this assignment, you are to create an array of structs and sort
the array.

1. create a struct with (at least) 3 fields
2. create an array of structs
3. read data into the array of structs (9-11 records)
4. print all of the fields in the array (line up the columns)
5. sort the array (in ascending order) on 1 field of the struct
6. print all of the fields in the array
7. sort the array (in descending order) on another field of the struct
8. print all of the fields in the array

keep in mind that the fields of a struct all go together, and
when you swap 1 field of a struct you need to swap all of the
fields in the struct.
