Purpose of lesson
In introductory programming courses, you will often hear a lot about something called structured programming.
While I don't claim to be an expert on structured programming, in comparison with more modern and complex programming concepts such as runtime polymorphism, structured programming is fairly mundane.
That's not to say that structured programming isn't important. It is important.
However, it is just a small bump in the road of learning that leads to an understanding of object-oriented programming.
The purpose of this lesson is to introduce you to the primary mechanisms of structured programming.
