Chapter 1. Used to C ++ By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ Regardless of your programming background, you may not get used to C ++. This is a powerful language with extremely rich features. But before you can exert its power and use these features effectively, you must make yourself accustomed to doing things in a C ++ way. This book describes how to do this. Some of the cont

The abdomen has poetry gas from China, all people should read more, reading good books.

whether P is a base class pointer? In fact, it is based on the Destructor (rtti) defined in the p declaration type. P is regarded as a base class pointer only when the Destructor are virtual. This explains the problems encountered above. When P was declared as base *, it actually points to a son object in the program, but we didn't ~ The base () is declared as virtual, so the compiler makes a static binding for us, that is, generating code that calls Base: Operator Delete (void. However, do not

In last June, I became interested in 3d graphics. I have read a lot of books, and I have never had time to write this code because of my busy work. This time I am going to organize my understanding of graphics. Although I have read "3d game programming master skills" several times, after all, it is not as profound as I did. Writing through my own thoughts will also have a sense of accomplishment. It has been almost a month since I completed the compilation system, and I have read some books that

. But there are two special cases to note.First, pointer constants are defined differently. Because constant definitions are generally placed in header files (many source files will contain them), apart from defining the types referred to by pointers as const, it is important that pointers are often defined as Const. For example, to define a char *-Based String constant in the header file, you need to write the const twice: Const char * const authorname = "Scott

Source: http://stackoverflow.com/questions/1434937/namespace-functions-versus-static-methods-on-a-class By default, use namespaced functions. Classes are to build objects, not to replace namespaces.In Object Oriented code Scott Meyers wrote a whole item for his valid tive C ++ book on this topic, "prefer non-member non-friend functions to member functions ". I found an online reference to this principle in an article from Herb Suter: http://www.gotw.

The recommended reading sequence is as follows: Level 1 Starting from "essential C ++", it is short and concise. You can learn more about the features of C ++.I use C ++ Primer as a dictionary and extracurricular reading, because it is too thick to read it in one breath. Level 2 Then, I started to transfer my role from effective C ++. This is the Bible. Please keep the 10 commandments and read them frequently.Next, the book titled predictional C ++, I personally think that the speech ability of
