Some pre-defined macros in the C standardSome predefined macros are specified in the C standard and are often used for programming. The following table is a list of some of the predefined macros that are often used.MacroSignificance__date__Date of preprocessing (string literal in the form "MMM DD yyyy")__file__string literal representing the current source code f

We encounter many macro definitions during development in the vs environment. These macros can be applied to code or used for compilation, engineering options, and other settings, in short, it is an essential tool in our development, and it is necessary to make a summary. Some macros are defined in C/C ++, and some macros are predefined in the VC environment. 1.

A major function of macros is to automatically generate code for us. If the template can generate various types of code (type replacement) for us, the macro can actually generate new Code (that is, replacing and adding symbols) for us on the symbol ). 1. Macros can be defined like functions. 2. if a macro requires a parameter, you can skip it. The compiler will warn you (the macro parameter is not enough)

From: http://blog.csdn.net/strikebone/archive/2007/11/02/1863523.aspx Here is a question about macros. I have used ATL's String Conversion macros, including w2a, which I don't quite understand at first. To use these macros, you must use uses_conversion at the beginning of the function to initialize some local variables. Use it, but let's look at the macro defini

1. Macro is a replacement that is completed by the C Preprocessor before compilation. 2. Differences between macro text replacement and typedef: For example, the difference between typedef int X [10] And # define x int [10] (1) The macro type name can be extended with other type specifiers, but the type name defined by typedef cannot. Eg, # Define peach int Unsigned Peach I;/* No problem, pai_^ */typedef int banana; Unsigned banana I;/* error, invalid, */(2) when several variables are declared

The ansi c standard has several predefined macros: __file _ date _ time ___ _ line _. _ Line __: inSource codeInsert Current SourceCodeRow number; _ File __: insert the name of the current source file into the source file; _ Date __: Insert the current compilation date into the source file _ Time __: Insert the current compilation time into the source file; _ Stdc __: when requiredProgramWhen the ansi c standard is strictly followed, this id

Excel2003 Tutorial 60, how to record the Macros command in Excel. Demo Animation Operation Steps It's perfectly OK to say, "Macros" is the essence of Excel, how to record a macro? Let's take a look at the specific recording process by recording a macro with a setting heading "Center Across columns": Execute the tools → macros → record new Macro comman

Excel2003 Tutorial 57, create a Form command button with macros. Demo Animation Operation Steps It's not easy to call macros by running the Macros dialog box, call macros through shortcut keys, and if you can't remember a lot of macros, let's add a button to the Ex

MacroOur calculator program, with 1234 corresponding to subtraction, is a bit of a hindrance to people reading. After one months to look at this code may not be able to think of 0123 or 1234, but also to find in the code, if you can represent the four number of arithmetic to take a meaningful alias, a look is to know what corresponds. No problem, use a macro. The following is the fifth edition of our Calculator program://define arithmetic macros#defin

program in or out of the compilation commands, such as # if and #ifdef, and usually converts the excluded statement to a blank line.(3) Macro expansionThe preprocessor expands the macro reference that appears in the source program file into the corresponding macro definition, which is what this article describes as the function of # define, which is done by the preprocessor.The source program processed by the preprocessor differs from the previous source program, where the work performed is pur

1. Hybrid macros. As styles become more and more complex and require repeated use of large sections of styles, using variables cannot achieve our goal. At this time, the mixed macros will be used. When using a hybrid macro, you must first declare a hybrid macro. When declaring a hybrid macro, there are two types: A Mixed Macro without parameters and a Mixed Macro with parameters. 1.1Declaration of mixed

ZZ from:http://blog.csdn.net/musein/article/details/742609==================================================The __init and __exit declarations is special kernel macros designed to tell the kernel to flag thesefunctions for special handling in cases where they is compiled in statically rather than included asparts of modules.The __init declaration allows the kernel to reclaim the space used by initializationfunctions, while the __exit declaration tells

Compilation: assemblyGuess: So this macro is related to the assembly?!Reference: Some of the constant macros are referenced by both C and ASM, while C and ASM differ in the processing of the immediate number symbol . In ASM, directives are adopted to differentiate whether the operands are signed or unsigned, rather than through the operands. and C is through the property of the variable, not through the operator. c If you want to indicate that a cons

expansionThe preprocessor expands the macro reference that appears in the source program file into the corresponding macro definition, which is what this article describes as the function of # define, which is done by the preprocessor.The source program processed by the preprocessor differs from the previous source program, where the work performed is purely a substitution and unwinding, without any computational function, so as long as you can really understand this when learning the # define
