                      2: Write a program that counts the number of vowels 
                      3: in its input (excluding 'y').  Don't forget to define
                      4: the value of EOF at the beginning of your program.
                      5: #once #create Ref
                      6: This line contains some vowels, including
                      7: the letter 'y'. It also has a capital letter, I think.
