/* Hellos.java by Craig Persiko
   CS 111A Solution to in-class exercise:
   Write a program that outputs "hello" to the user as many times as 
   specified. So ask the user how many times to repeat the greeting, 
   then use a loop to output it that many times. For an extra 
   challenge, alternate between captial and lower-case words, such as:

  How many times should I say hello? 5
  hello HELLO hello HELLO hello
