Knowledge Base/CPP/More Effective CPP

 

From The Thalesians

This is essentially the table of contents of Scott Meyers' book More Effective C++. The same table of contents is available on Amazon.com, but not on Amazon.co.uk (check out the "Look Inside" feature). In my view, every serious C++ programmer should read Scott's book. Of course, you need to read the entire book. The chapter titles will only make sense if you have read it. If you haven't read it and the titles still make sense, you are still missing a lot. I would read the book.

Contents 1 Basics 2 Operators 3 Resource management 4 Efficiency 5 Techniques 6 Miscellany

Basics

1. Distinguish between pointers and references
2. Prefer C++-style casts
3. Never treat arrays polymorphically
4. Avoid gratuitious default constructors

Operators

5. Be wary of user-defined conversion functions
6. Distinguish between prefix and postfix forms of increment and decrement operators
7. Never overload &&, ||, or ,
8. Understand the different meanings of new and delete

Resource management

9. Use destructors to prevent resource leaks
10. Prevent resource leaks in constructors
11. Prevent exceptions from leaving destructors
12. Understand how throwing an exception differs from passing a parameter or calling a virtual function
13. Catch exceptions by reference
14. Use exception specifications judiciously
15. Understand the costs of exception handling

Efficiency

16. Remember the 80-20 rule
17. Consider using lazy evaluation
18. Ammortise the cost of expected computations
19. Understand the origin of temporary objects
20. Facilitate the return value optimisation
21. Overload to avoid implicit type conversions
22. Consider using op= instead of stand-alone op
23. Consider alternative libraries
24. Understand the costs of virtual functions, multiple inheritance, virtual base classes, and RTTI

Techniques

25. Virtualising constructors and non-member functions
26. Limiting the number of objects of a class
27. Requiring or prohibiting heap-based objects
28. Smart pointers
29. Reference counting
30. Proxy classes
31. Making functions virtual with respect to more than one object

Miscellany

32. Program in the future tense
33. Make non-leaf classes abstract
34. Understand how to combine C++ and C in the same program
35. Familiarise yourself with the language standard
