overview

[1] Don’t panic! All will become clear in time;
[2] You don’t have to know every detail of C++ to write good programs;
[3] Focus on programming techniques, not on language features;

there are six parts of this book:

1.Introduction　　ch1-3

　　　　overview

2.Part1　　ch4-9　　

　　　　a tutorial introduction to C++’s built-in types and the
　　　　basic facilities for constructing programs out of them.

3.Part2　　ch10-15

　　　　a tutorial introduction to object-oriented and generic programming

　　　　using C++.

4.Part3　　ch16-22

　　　　present the C++ standard library.

5.Part4　　ch23-25　　

　　　　discuss design and software development issues

6.Appendices　　

　　　　A-E provide language technical details

Advice:

[1] When you program, you create a concrete representation of the ideas in your solution to some
problem. Let the structure of the program reflect those ideas as directly as possible:
　　[a] If you can think of ‘‘it’’ as a separate idea, make it a class.
　　[b] If you can think of ‘‘it’’ as a separate entity, make it an object of some class.
　　[c] If two classes have a common interface, make that interface an abstract class.
　　[d] If the implementations of two classes have something significant in common, make that
　　　　commonality a base class.
　　[e] If a class is a container of objects, make it a template.
　　[f] If a function implements an algorithm for a container, make it a template function implementing　　　　
　　　　the algorithm for a family of containers.
　　[g] If a set of classes, templates, etc., are logically related, place them in a common namespace.

[2] When you define either a class that does not implement either a mathematical entity like a
matrix or a complex number or a low-level type such as a linked list:
　　[a] Don’t use global data (use members).
　　[b] Don’t use global functions.
　　[c] Don’t use public data members.
　　[d] Don’t use friends, except to avoid [a] or [c].
　　[e] Don’t put a ‘‘type field’’ in a class; use virtual functions.
　　[f] Don’t use inline functions, except as a significant optimization.
