VowelSearch.cpp

//Write a method called vowelCount that accepts a String as a parameter and produces/returns an array of integers representing the count of each vowel in the String. 
//The array returned by your method should hold five elements: the first is the count of the 'A's, the second is the count of 'E's, the third 'I"s, the fourth 'O's and the fifth the number of 'U's. 

//Your count should check for both upper and lower case versions.

//For example the call vowelCount("I think therefore I am") should return the array [1,3,3,1,0].

#include <tuple>  // tuple library is  used to return multiple values
