Programming Assignment Six: Write a C++ program that asks the user for a single character value, but over and over, for as many characters that the user wishes to enter.

There should be a function called IsVowel(char letter)that returns true of the character in letter is a vowel, andfalse otherwise. The best way to understand what is wanted is to study the output.
