Question

There is a children's "secret language" called "Pig Latin" which supposedly allows conversation the uninformed (such as parents) cannot understand. The rules are:

If a word begins with a vowel (aeiou) then append "way" to the word. For example, "Aggie" becomes "Aggieway".

Otherwise, remove the consecutive non-vowels from the beginning of the word, append them to the end of the word, and append "ay" to the word. For example, "whoop" becomes "oopwhay".

Write a program named hw5pr1.cpp which reads words from a file named in.txt and writes the words in Pig Latin to a file named out.txt.

So if in.txt contains the words

I love Reveille

This is the street

then the words

Iway ovelay eveilleRay

isThay isway ethay eetstray

will be written to out.txt.
