Earlier quoted context omitted.
Gee, write a program using what you just learnt and see if it works. You want someone to tell you what program to write?! I assume it's a book for kids, or a school textbook, when I see exercises like that. I don't understand the demand that books not only tell you things, but tell you how to learn everything in them too. Apologies, I really tried to make this not sound condescending!
The expert you're learning from probably has a better idea than you do of what programs you should write given (a) your presumed knowledge level and (b) what programs would help you learn the fastest and/or the most relevant features. Including good exercises is an extension of the purpose of the book itself.
Maybe, but they know nothing about (a) why you're reading the book, (b) what you know/don't know already, (c) your learning style, (d) your speed of learning etc.
