Really?! An Omelette is the best example you could come up with? fridge contents? types of cheese? wanted food? Who programs that stuff? Is that the level of abstract that your brain can handle? What is wrong with you authors?!

Somebody gave me this book for free. I just browsed through its first 70-80 pages. I am afraid I have to through it away! You know?! With the rest of the spoiled food!!!!!

Here is a suggestion to the authors. Pick up a Murach book to see how a programming book is written!!
Here is another suggestion to the authors. How about if you use something close to a real life application? like a teacher wants to keep record of its students grades, or a company needs to keeps track of its emplyees, salaries, etc.
