[[email protected]]

Can you please share example to clearly indicate when private and protected inheritance is used?

Look towards the end of this example -
Why do my compiles take so long?

I think you should turn the page and come back to this later when you feel a need for something in between public and private inheritance.

Good point. Once you turn that page, more likely than not you will never need to go back and read it.

I must have skipped something like 90% of the C++ pages and here I am writing perfectly fine C++ programs!

One big advantage of being a 10% C++ programmer is that your code is easy to read and understand by a majority of other C++ programmers as well.

And even Stroustrup, the inventor of C++, is concerned that C++ has become too complex and hard to learn. I say that's no problem. For the 10% C++ programmer C++ is an easy language to learn and use.

I would say that if you are only familiar with 10% of something, you are not really qualified to decide how “fine” your product is.
For comparison, let’s say an average English-speaking person uses 50,000 words. If you only know and use 5,000 – you WILL be “easy to read and understand” (you are correct here). But it will be hard for you to express any non-trivial thoughts.

I interpreted nuzzle's 10% as being 10% of the entire C++, so it would be akin to using 50000 words like the average person instead of the hypothetical 500000 words of the language. Of course, a percentage of C++ can only be a rough estimate, and a figure as low as 10% is probably an exaggeration to get the point across.
