Your programs must have inline, online, and external documentation. They must be user friendly, and check for errors in user input. They should also have appropriate messages. At this point in the course, use all the features of the language that you have learned, and read the API to apply new ideas to your source.

Once you've looked at the questions, try to divide your solutions into functions and variables. When you need to store something, that's your clue to make a variable. When you need to DO ONE THING, that's your clue to write a function.

1. Convert a date in the form MMDDYYYY into 1 March 2016.

2. Replace all sequences of blanks in a given string with a single blank.

3. Morse code. Convert given text into Morse code:
