// The purpose of this program is to obtain an array string
// (word) from the user through the keyboard, and display the 
// first and last letter of the word on the screen. If the first 
// letter in the word entered by the user begins with a consonant,
// the first character of the word is moved to the last position
// and append "ay" is added to the end of it. However, if the 
// word begins with a vowel, the program simply adds an "ay" to 
// the end of the word.  
//
// Table of Variables:
// -------------------
// s1    = String Array Variable Input by user
// s2    = String Array Variable that holds the first letter of the
//         string input by user
// s3    = String Array Variable that holds user input minus the 
//         first letter of the input array
// s4    = String Array Variable that holds "ay" inside it
// n     = Variable that contains the first array element number 
//         that does not contain a vowel (aeiouAEIOU) inside it
// count = Loop Counter which exits the loop once 5 words are 
//         entered by the user
