1. Write a function numVowels() that takes a string representing a file name as a parameter and returns the number of vowels (both upper- and lowercase) that appear in the file. For the purposes of this question a vowel is one of a, e, i, o, or u. The following shows how the function would behave for several sample files that are included in the zip file with the assignment template: The purpose of this program is to print the number of vowels in the text files(not included).

Output should look like this:

>>VOwelCount (example.txt') 19 >>> vowe!count ( ' Robot. txt ' ) 330 >>>VOwelCount (hamlet.txt) 328 Ln: 11 Col: 4
