C++

This evening, I finally read "Deep Exploration of the C ++ object model" for the first time. A month ago, I wroteProgramI feel uneasy. Sometimes I want to optimize it, but I don't know how to do it. At that time, I was eager to understand the

1. The most convenient thing is the built-in catlregexp in ATL. However, POSIX standards are poorly supported and very slow.2. Boost is very famous, but too bloated and fast.3. In the past, Microsoft Research Institute had a group engaged in Greta,

1. All compilation systems requireOne byteTo storeOne character 2. Place a character constant in a character variable. Instead of storing the character itself in a memory unit, it stores the corresponding characterASCII codeStored in a storage

Holding a large number of pointers in a vector will cause a large amount of memory loss. Consider the followingCode:   Int nsize = 1000000; //////////////////////////////////////// /// // STD:: vector V1; For (INT I = 0; I V2; For (INT I = 0; I

MCU previously writtenProgramAlways write the functions and variables used in a C file. Later, when a large project occurs, the program moves thousands of lines. This method will undoubtedly cause n problems, I believe everyone has an experience!

The following are some bugs I found when I checked the first volume of C algorithm. If any of them is incorrect, I would like to thank you for your attention. (Bugs will be updated later) * When Using arrays, foreigners generally like to use the

In the project, because mobile devices need to request services from the management center, the management center uses the concurrency mode to process requests (corresponding to the polling mode ), because a thread needs to be created to provide

Volatile reminds the compiler that the variables defined after it may change at any time. Therefore, the compiled program will directly read data from the variable address every time it needs to store or read the variable. If there is no volatile

C-language structure alignment is also a common topic. This is basically a mandatory question for the interview questions. How is the structure aligned? The alignment principle is summarized below, without the # pragma pack macro: Principle 1.
