A classic example. The classic example of using preprocessing and macro definitions is to add a header file to prevent the header file from being compiled two times. Imagine this situation, there is a file headerfile.h it is included in the Headerfile1.h, and also included in the Headerfile2.h, there is now a CPP file, Implement.cpp contains Headerfile1.h and headerfile2.h: #include “headerfile1.h” #include “headerfile2.h” Suppose a global variable

Workflow Terminology and Definitions Work Flow It's simple, it's the process of working from start to finish. A workflow consists of process logic and alignment rules. The process logic defines the order of tasks and the alignment rules that must be followed, as well as the deadlines and other business rules that are implemented by the workflow engine. Process Definition A graphical process definition or flowchart that

People who are new to MFC programming are often intimidated by various macro definitions and preprocessing commands generated by the MFC wizard. However, preprocessing and macro definition are a powerful tool in C language. They can be used for simple source code control, version control, warning, or some special functions.　　A classic exampleThe most classic example of using preprocessing and macro definition is to add a header file to avoid the heade

Some days ago, some netizens asked: what is the difference between an array defined by int[] A in Java and an array defined by an int a[]?At that time did not look closely, replied directly, in Java, the two are the same, no difference.Looking back carefully, there is a slight difference.according to the normal Java programming specification, the definition of the type is then the end of the variable name, thus int[] A is compliant with the Java Definition Variable specification (recommended usa

Macro definitions are used in many ways, such as defining heights, judging iOS systems, tool classes, and documentation such as file paths and server-side API interfaces. In order to quickly locate and understand the function of a macro, it is best to put it in a specific header file when defineddefine a macro for a dimension classDimensMacros.h//Status Bar Height#defineStatus_bar_height 20//NavBar Height#defineNavigation_bar_height 44//status bar + n

the 5 major processes of project management are:Start process: Approve a project or stage, and have the intention to proceed down the process.Planning process: Develop and improve project objectives, and select the best solutions from a variety of preparatory programs to achieve the objectives of the projects undertaken.Execute the process: coordinate the personnel and other resources and implement the project plan.Monitoring process: Through regular collection of performance data, to determine

As we all know, a macro definition is a compile-time constant. And OC is a dynamic language.Two macro definitions for 1.iOS system version1 __iphone_os_version_max_allowed //iOS system version maximum allowed 2 //iOS system version minimum requiredUsing these two macros will only eliminate the compiler's warning. Because OC is a dynamic language, the system version also needs to be judged. For example:2. Assertions /** @brief Applicable: Objectiv

Definitions and terminology of treesFlyfish 2015-7-9A tree is a finite set of n (n>=0) nodes. N=0 is called an empty tree. in any one of the non-empty trees:1) There is only one specific node called root (Root)2) When n>1, the remaining nodes can be divided into m (m>0) non-intersecting finite sets. T 1 、 T 2 、...、 T m , each of which is itself a tree, and a subtree called t

Three definitions of PHP strings: single quotes, double quotes, delimiters 1, and single quotes: the simplest way to specify a simple string is to enclose it with single quotes (characters. In a string enclosed by single quotes, to represent a single quotation mark, you must use a backslash () to escape it. it is the same as many other languages. If a backslash is required before single quotes or at the end of a string, two backslashes are required. T

Duplicate definitions may result in an error in setting the object reference to an instance.Author: icech Generally, in C #, the error "the instance where the object is not referenced" is that the control name does not correspond to that in codebehind. For Beginners, repeated definitions in encoding can also cause this problem. The following is an example: Using system;Using system. collections;Using syste

inline should appear in the declaration of functions. Although this detail does not affect function functionsA basic principle of high quality c ++/C programming style is introduced: Declarations and definitions cannot be confused, and users do not need or need to know whether functions need to be inline.The member functions defined in the class declaration will automatically become inline functions, for exampleClass{Public:Void Foo (int x, int y ){.
