/*1- Create a structure named Employee. Include data fields to hold the Employee's ID number, first name, last name, and hourly pay rate.
Create an array of five Employee structures. Prompt the user to enter data for each Employee. Do not allow duplicate ID numbers to be entered.
Then prompt the user to choose whether to search for an Employee by (1) ID number, (2) last name, or (3) hourly pay. After the user chooses the field on
which to search, prompt the user for the search value. Display an error message if there is no Employee with matching criteria, otherwise display all the
data for every matching Employee (more than one Employee might have the same last name or pay rate).*/
