Strings

You have been asked to construct a program that will translate English to Pig Latin. Following good programming practice, you
realize that the solution will make heavy use of functions. You plan to start by constructing a function that will convert an
English word into Pig Latin. Pig Latin is a fictitious language derived from English using a few simple rules.

1.) If a word starts with a vowel (a, A, e, E, i, I, o, O, u, U) then the translation is formed by adding a "way" to the end of
word. e.g. "at" becomes "atway", "egg" becomes "eggway"

2.) If a word contains no vowels (a, A, e, E, i, I, o, O, u, U) then the translation is formed by a adding a "way" to the end of
word. e.g. "my" becomes "myway", "by" becomes "byway"

3.) If a word starts with a consonant and contains a vowel, the translation is formed by moving the consonant(s) up to the first
vowel to the end of the word and adding an "ay". e.g. "bat" becomes "atbay", "that" becomes "atthay", "three" becomes "eethray"

4.) Words that start with an initial capital letter should be translated to words with an initial capital letter.
e.g. "Houston" becomed "Oustonhay", "Iceland" becomes "Icelandway", "Marry" becomes "Arrymay"

=================================================================================================================================

Deliverables:
Write a program using good style, indents, descriptive variable names, comments, etc..
Greet the user and provide a few lines about what the program is/does.
Prompt the user to enter an English word.
Translate the word from English to Pig Latin.
Output the original word and the translated word.
Prompt the user to continue.

=================================================================================================================================

Hints: You are free to construct any functions you may need to perform the translation. Be sure to keep a copy of the original
word. You can use assume a string size of 50, though most words will be much smaller.

You will probably want functions to:
Input the word.
Find the length of a word.
Determine if a given letter is a vowel. (a helper function to make life easy for you)
Determine if a word starts with a vowel (rule 1).
Determine if a word contains a vowel (rule 2).
Determine where the vowel is in the word (rule 3).
Determine if the word has an initial capital letter (rule 4).
Output the English and Pig Latin words.

=================================================================================================================================

Example Output:

This program will translate a word from English to Pig Latin.

Please enter a word: Cat

Cat becomes Atcay.

Would you like another word? (Y/N) y

Please enter a word: by

by becomes byway.

Would you like another word? (Y/N) Y

Please enter a word: Away

Away becomes Awayway.

Would you like another word? (Y/N) Y

Please enter a word: at

at becomes atway.

Would you like another word? (Y/N) Y

Please enter a word: tree

tree becomes eetray.

Would you like another word? (Y/N) n

Ankthay ouyay!
