main()

• Update main so that it repeatedly asks the user for a sentence and prints out the statistics. Exit when the input is an empty string, no characters.
  • It makes sense to update the prompt to tell the user how to exit the program.
  • If there is no initial input, that is, if the user presses Enter immediately, exit the program without printing any statistics.
  • This shall use a loop. (So, don't include a second call to main to get this to happen again. That would be recursion
  • when you press return it will end the program and print out Good-bye.
  • Count the words in the sentence.
  • Word count

  • For the purposes of this PA, a word is any contiguous combination of alpha-numeric characters. So 'alpha-numeric' is 2 words; the hyphen is not alpha-numeric. Hint: isalnum
