In the last text, we designed a very simple list, which used the process of design in the fifth and six chapters of this book, these things are the most difficult part of the C language, and academic discussions are everywhere. The usage and characteristics of the pointer can not remember, and individuals think the best way is to practice, and the problems encountered in practice are often the most common, most important knowledge points, as for those special features, etc. Those who are commonplace will not understand them.

The seventh of this book. The contents of the eight chapters are strictly sought by the language itself. Yes, I think this said, this is related to the "library" understanding, what is the library? It is something that others have written (type, function, constant, etc.), our program can be called according to the interface they provide, to save us developed time and energy, but must understand that there is no library, we can't Write something. The content of Chapter 8 is to tell us how to write a similar standard IO library based on the specific OS, yes, the library must be systematic, of course, you can maximize his portability (this is the standard library) Successfulness).

Of course, for most program development, the use of libraries may be one of the most important indicators of program design level. No one will be stupid to put things don't use, and the time to write a lot of time to write one (of course As a study study, it is just the opposite). Once, a netizen said that the standard C and c can't do it. When I propose against opinions, this person is highly questioned: "You don't have Win API to write a form to show me!?". I have no words, because I have to say too much, such as: Is the API arise? Can I say that C and C do not have this ability? I have no honor, even if you have, you can take it out to him. So I choose silence, any success of human beings is based on the former, so that we have proud efficiency.

Back to the topic, the standard library is very large (otherwise not to go), the OS system call is also a lot, for these suggestions: remember that it is common, other things like it. That is, for example, in the C standard library as an example, most of the books mentioned in Appendix B need to be remembered. As for another, everyone can take a look at the "C Language Reference Manual".

All right. The summer vacation is over, this note can also end (yes, I heard someone said: "This guy is finally shut up", there is a self-knowledge of the Ming? Oh, maybe "he" knows the mastery.), Write notes are the author A learning habit, the editor of 9CBS is just to recommend a few good books to everyone, and the author will ask the author to modify some targeted words, such as "Summer Holiday Learning Notes", etc., and reprint here. For students, there is a platform for communication, and your own error can be corrected in time. No matter how the author's level, he wrote his own ideas and organized his knowledge and put forward his kind suggestions. This is not easy. But what do we see? Non-thinking finger. I didn't see the text, I took the code. The meaningfulness, probably to show your own level, more people say that the author is coming for d currency (I have seen in another book review in this site). In fact, people who have some understanding of this site know that the money to buy and bought books will not be comparable, these phenomena can't be said to be a regret.

Finally, if there is any suggestions for me, I can visit my blog: http://blog.9cbs.net/owl2008/, but to declare first, maybe 9cbs can't reject some self-righteous critics. But I am absolutely unwelcome, I have to read my things, you first gave me the minimum respect. Note: This is the end of the series of second bookstores. I will write in this BLOG station follow-up notes on this BLOG station.
