<h2>Techniques</h2>
<P>I had the second part of this book all figured out: I would introduce advanced features of C++ one by one, with examples. I would do templates and exceptions and write a chapter about my favorite resource management. Then I would show the perils of concurrent programming and how to avoid them, the clever tricks with virtual memory and I抎 finish up with a series of Windows programs.
<P>Then I started preparing a course for students and suddenly realized that it wouldn抰 work. Well, it would in some way, but not the way I wanted it. I didn抰 want to come up with a random bag of tricks, like so many "experience" books do. (Nor did I want to produce a new theory of program development.) What I really wanted is to show how programming works in real-life situations. In real life you don抰 come up with a new trick and start looking around for the opportunity to use it. A much more likely scenario is that you are faced with a problem that has to be solved and you need to know what your options are. Or you are trying to spot potential problems in your or somebody else抯 code and prevent them.
<P>The problem is that, in order to demonstrate the usefulness of advanced techniques, one needs to work with examples of more substantial programs. Of course, I could keep inventing stories like: "Imagine you wrote a large system that was supposed to distribute luggage in a big airport. The system was just allocating an entry for a suitcase when it ran out of memory. A null suitcase was created and caused a plane to GP-fault."
<P>And then I realized that there is no better opportunity for a programmer to learn about programming than by taking part in code reviews. This is how my coworkers and I honed our skills, both when defending our own code and when critiquing others⌨️ 快捷键说明
