How Do Functions Function

Today was another day where Mr. Arkin was present and accounted for, yes!  The three things we did in class today were: looking at algorithms of some of the programs for the sub-strings assignments, learn a little bit about functions, and check how to make some of the class's programs a little bit easier to type and understand!  I noticed that at the beginning of class, I did not how to write or how functions work, but as the class went on I started to understand a little bit better-another great lesson from Mr. Arkin.  Today for homework we are trying to implement some functions into our sub-string assignments...boy I hope I understand how to do it.  And to end a short reminder that our test is coming up very soon :o!
