[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.
