Class 5: Procedures Practice

Here are the materials from class 5: Notes (PDF), Slides (PPTX). (Note: I did not actually present slides 8-14 in class, but they are included here. They show compare the size of the primitives, means of combination, and means of abstraction, between Scheme, English, and C++, to give you an idea of how hard the different parts of a language are to learn.)
