 * The program contains an array that holds 10 ZIP codes to which a company delivers. 
 * Prompt the user of the program to input a ZIP code and then display a message on screen 
 * that indicates whether the ZIP code is one to which the company delivers or not. 
 * Finally display all ZIP codes in the array in descending order.
