Drill and Exercise Code

The book's Web site has some exercise solutions , which should be used as examples of how to use C++ in preference to the code in this directory. The code in this directory is provided because they may well help if you get stuck, and you are asking yourself “How on earth can I answer this one?”

The code here was written primarily for the following purposes:

to check that I had correctly understood what Bjarne Stroustrup was saying and exactly what the C++ standard allows, and
to check that doing the drills and examples was possible using only the facilities taught up to that chapter, in the environment I would use for teaching, and
to check that the supplied materials would run correctly (and preferably without warnings) in the environment I would use for teaching.

In particular:

they are not always written in a good style, and
I did most of them in some chapters but only a few in others (though I did all that looked as if they needed something new), and
they rarely include the error checking and commenting that the book asks for, and
they haven't been properly tested, and some are deliberately incorrect (to check on failure modes), and
they don't all do the drill or exercise exactly, because I fairly often got bored :-)

Don't do as these examples do - do as the book says!
