A free e-Book: learn from real examples how to avoid bugs


Here is a small e-Book for your attention: The Ultimate Question of Programming, Refactoring, and Everything. This book is intended for C/C++ programmers, but it could be of interest for developers using other languages as well.

What makes the book peculiar is the descriptions of real, not theoretical cases at the base of it. Each chapter starts with a code fragment taken from a real application, and then the author gives various tips of how this bug could be avoided. The questions touched upon in this book can help the readers improve the personal coding style and the coding standards used in the team.

The book covers 42 topics. In spite of the simple titles of the chapters, the bugs found are really various and non-standard. In addition to that, the text provides a lot of links to interesting materials that give more details on topics. To make more use of this book, please don’t hurry and go to the links provided.

7. Do not call the alloca() function inside loops
8. Remember that an exception in the destructor is dangerous.
9. Use the '\0' literal for the terminal null character

31. In C and C++ arrays are not passed by value
32. Dangerous printf
33. Never dereference null pointers
34. Undefined behavior is closer than you think

36. If something strange is happening to your PC, check its memory.
37. Beware of the 'continue' operator inside do {...} while (...)
38. Use nullptr instead of NULL from now on
