In C language, usually the operation of the string is a lot of, understand the commonly used string function will make C programming very fast! Here properly tidy up, convenient for later reference. When used, a lot of pointers are used, note the

Today, a problem suddenly comes to mind, and sometimes there are multiple responses to the same event, especially in game AI, where the most appropriate scenario needs to be taken, which is best suited to the outcome or impact of each scenario, so

write a macro definition, the function is to convert the number of an int to the odd and even bits of the interchange, for example, 6 of the binary is 0110, the first and second interchange,// third and fourth position interchange, get 1001, the

C + + assigns an assignment expression as one of the expressions, so that the assignment can appear not only in the assignment statement, but also in other statements (such as output statements, loop statements, and so on) in the form of an

It is easy to register a C + + enumeration in LUA code, just like registering a global variable. We use the enumeration name as a namespace to avoid conflicting enumeration registrations. The registered enumeration is stored in the Global

This article has been transferred from the post-C + + preprocessor directive # define, #ifdef, #ifndef, #endif .... This blog post is particularly well written, especially reproduced.In this paper, we mainly record the pre-C + + preprocessor

The organization of the source code: the function template should be able to see its definition when it is instantiated-this is something to be aware of.Include modelThe Declaration and definition of the template are placed in the header file, but

Character literals are typically represented by a pair of single quotes. Char types are typically initialized and assigned with character literals. Because the char type is a single-byte length, when a variable of type char is assigned a character

Generics overviewGenerics are a special mechanism provided by the CLR that allows us to write code with a type placeholder and then provide a true type when an instance of the type is created. In many cases we can extract or refactor the behavior of

Today the IP network uses 32-bit addresses, dotted decimal format, such as 172.16.0.0. Address format: IP address = Network address + host address or IP address = host address + subnet address + host address.IP Address TypeWhen the internet was
