motives A few days ago to see an interview question: Write a "standard" macro min, this macro enters two parameters and returns the smaller one, which mentions two topic points: knowing how to carefully enclose the arguments in parentheses in a macro is a side effect of a macro, such as what happens when you write the following code. least = MIN (*p++, b); Usually will also use the macro definition, the understanding of the macro is not particularly

What is a class constant? What we can understand in PHP is that the value is constant, so what is a class constant? In fact, the class constants are also easy to understand, we can always keep the constant value of the class is called constants, and this constant can be called the class constant. Be sure to remember that you do not need to use the "$" symbol when defining and using constants. A class constant belongs to the class itself, not to an object instance, and cannot be accessed through

file of the class Person.h (which is usually done in this file), There is also a person.m file, which is generally implemented as defined in the header file. This is also a continuation of the C language of the project structure it. General header files are only responsible for defining functions, and. c files are responsible for implementing specific functions. It's similar here.Here's a look at the definition format for the class in the Person.h he

Always thought that my C language can still, although not superb, but at least more familiar with it. But a while ago read a tweet, and then Baidu a bit of C language is not the exact type. Found me. C language is not completely type and the use of a very wide range of delay definitions have no concept. These two days looked closely at the relevant concepts and experimented with the code.This article is structured as follows: Introduction to the concept of non-complete type of C languag

to maintain stable interfaces. Currently, there are many open source code libraries, such as QT, glibc, and GTK. However, most of them do not allow users to directly use the source code, but provide binary libraries with the source code for your reference. For the second type, the Library only provides a limited description for users, so that users can use the library, but do not know the specific implementation of the library. The usage of this library is typically provided to the user's heade

C ++ summary type, object definition and declaration, object initialization and assignment, initialization and assignment1. Object TypeThe object type determines the size of the memory space occupied by the object, the layout of the memory, the range of stored values in the memory, and the operations that can be performed on the object, because the object type determines the operations that can be performed on it, the const attribute can also be seen

In program design, the definition of variables and the declaration of variables are used all the time, but sometimes we are not very clear about the concept, know how it is used, but do not know how a thing.Below I will simply introduce their differences as follows:There are two scenarios for declaring a variable :(1) One is the need to create a storage space (definition, declaration).For example, int A has

The first part:To explore this problem, or because of the error encountered during programming:Hint Tcplink is not defined, Tcplink is a function I wrote to the supervisor to hear the TCP connection request to allocate a new thread, but write it down, just like this:If it's in C + +, it's easy to solve the problem. At the beginning of the file, plus the declaration of the function is OK, so not only convenient, but also to maximize the appearance (fog). But the problem is, Python does not seem t

Original post http://hi.baidu.com/bwandmff/blog/item/56876b30a31d519da9018e9a.htm Before discussing global variables, we must first understand several basic concepts: 1. compilation unit (module ):Today, when IDE development tools are widely used, many developers are no longer clear about the concepts of compilation. Many programmers are most afraid of handling connection errors ), because it does not give the specific location of your program errors as a compilation error, you are often annoy

Macro definition is a precompiled function, precompilation is also known as preprocessing, is the preparatory work for the compilation of the stage. Handle the instructions at the beginning of the #, such as copy #include contained file code, #define宏定义的替换, conditional compilation, etc.Benefits of using macro definitions: The benefits of using macro definitions can improve the versatility and readability of programs, reduce inconsistencies, reduce inp
