Title: Add exercises of Chapter 9.

Interesting chapter with more "real" programs.

Note: I skipped exercises 4 and 5 on purpose. Although I'm not happy with this I decided to move forward reading the book specially because the next chapter (regarding types and classes declarations) is something that I'm very excited to learn.
