Let's take a look at an example: #include　 template　 class　Fibnacci { public: 　　　　static　const　int　value　=　Fibnacci::value　+　Fibnacci::value; }; template　<> class　Fibnacci { public: 　　　　static　const　int　value　=　0; }; template　<> class　Fibnacci {

To facilitate the analysis and observation of the object's memory layout, I set the struct Member alignment option to 1 bytes when code was generated, and the default is 8 bytes. If you are compiling the code in your own project, please do the same

A while ago in the work of the project, encountered the COM components of the call and use problems, then research and good for a while, before the middle of the link through, now write to provide convenience for everyone, here contains four types:

Log4cxx is a good library, using the configuration file can be very flexible to use it. To be specific, first of all, of course, in your C + + code, write a log of the various things #include #include #include int _tmain(int argc, _TCHAR* argv[]

1.4 Operation of Pointers 1.4.1 Assignment operation The assignment operation of a pointer variable has the following several forms: 1.4.1.1 pointer variable initialization assignment is as follows: int A; int *ip=&a; 1.4.1.2 assigns the

1.3 Pointer and memory management With pointers you can write data to any location in memory, however, once your program has a wild pointer ("wild" pointer), a pointer to a wrong location, your data is dangerous-data stored in the heap may be

For the sake of need, I have recently studied C + +. A simple familiarity with this language that I have forgotten for years. As a study, record here. The difference between C and C + + is also compared. Code for C: #include #include /** 　*　

In C + +, there are two main ways to define a constant 1. Symbolic Constants (#define) 2. Constant value variable (const) Symbolic constants are defined in a way that is not related to C + + itself, it is a compiler directive, or preprocessing

In the game development, AI is one of the most basic problem is the search algorithm or path planning algorithm, three years ago, I have implemented a "graph algorithm" of the shortest Path planning algorithm, however, in the game, we usually

The most recent is a time project may need to provide SMS functionality, customers as an SP side to provide SMS business; A search on the internet, found a relatively good CMPP30 class code, the code basically realized the CMPP3.0 protocol in the

C#3.0 has been introduced for some time, for various reasons, has not been to learn, these two days in the garden to see Lao Zhao's Save C # 2.0, but we really do it? It mentions some of the new features and advantages of c#3.0. It reminds me of my
