audacity macro

(a) Symbolic constantsA macro definition is a substitution policy in C that uses a preprocessing command #define equate a string (lengthy) text with a name (called a macro) and then use the macro in bulk in the source code. In the preprocessing phase, replace the macros in the source code with the original text. For example, in the source code:#define PI 3.14T

" H.264/AVC Video Codec technology detailed" video tutorial has been in the "CSDN College" on-line, the video details of the background, standard protocol and implementation, and through a practical project in the form of the standard of the resolution and realization of H. A, welcome to watch. "The paper came to the end of the light, I know this matter to preach", only by themselves in accordance with the standard document in the form of code to operate, in order to the video compression codi

Statements in assembly language programs can be composed of commands, pseudo commands, and macro commands. Command: Each Command corresponds to a CPU operation. A pseudo-command is also called a pseudo-operation. It is an operation processed by the assembler during the compilation of the source program, they can complete functions such as processor selection, defining program patterns, defining data, allocating storage areas, and indicating program te

1,Use a # Before a parameter in a Preprocessor macro. The Preprocessor converts this parameter to a character array. (Original article: when you put a # Before an argument in a Preprocessor Macro, The Preprocessor turns that argument into a character array. This, Combined with the fact that character arrays with no intervening punctuation are concatenated into a single character array, allows you to make a

1. Rules and usage resolution for macro definitions(1) The parsing rule of a macro definition is that it is replaced by a preprocessor during the preprocessing phase, and the substitution is unchanged.(2) The macro definition substitution is performed recursively until the replaced value itself is no longer a macro.(3)

In GNU C, a macro can accept a variable number of arguments, just like a function, such as: 12 #define pr_debug(fmt,arg...) \ printk(KERN_DEBUG fmt, ##arg) Passing variable parameter tables with variable-parameter macros (Variadic macros)You may be familiar with the use of variable parameter tables in functions such as: 1 voidprintf(constchar* format, ...); Until recently, a mutable param

Reprint: http://www.zhihu.com/question/26584112 Basically, automatic installation has only advantages and no obvious drawbacks.Therefore, avoid manually installing the macro package. Packages that are normally required by MiKTeX can be installed automatically at compile time, or the package Manager installation will open.If you have individual documents that require special macro packages that are not in t

1.5 C language Program running process01 source program: Written by high-level or assembly language, C language source program extension. C02 Target Program: The source program is translated by the "compiler" binary code is the target program, its extension is. obj03 Executables: The target program is connected to the library function to form an executable program. Out#include intMain () {#definePI 3.14DoubleR,len,area; printf ("Please enter radius: \ n");//Prompt user to enter RADIUSscanf ("%LF

#defineThe command #define defines an identifier and a string. Each time the identifier is encountered in the source program, it is substituted with a defined string. The ANSI standard defines an identifier as a macro name and replaces the process with a macro substitution. The general form of the command is: #define Identifier string Attention:1. The statement does not have a semicolon. There

One, the macro definitionConcept: the macro definition is essentially a precompiled instruction that pays certain instructions to the appropriate variables before the program is run. The general preprocessor directives start with the # number, so the macro definition is also developed in #, the keyword is # define (definition

First say the difference between macros and functions:1. The macro does a simple string substitution (note that the substitution of strings is not a substitute for other types of parameters), whereas the arguments of a function are passed with a data type and can be of various types.2. The parameter substitution of a macro is handled directly without calculation, and the function call is to pass the value o

Transferred from: Http://www.jianshu.com/p/213b3b96cafeObjective:In the work, many small partners will PCH define some common macros in the file, but also afraid to write these simple macro waste of time, and sometimes forget how to define how to do? I am also in the work of the same. So here to share some common macro definitions, like the small partners can be used directly in the project (continuous upda

The Excel Macro button is set to the following steps: 1. The nature of the button is a macro, so before making the button, we first record a macro, the macros are ready, you can make the button. First open a table as shown in the picture, select the headline, and then we execute on the menu bar: Development Tools--Macros 2. Set the

A macro definition is one of the three preprocessing functions provided by C, which includes the following three types of preprocessing: macro definition, file inclusion, conditional compilation A macro definition is also called a macro substitution, a macro substitution,

Objective In the VS overview, we briefly review the history of vs. This article will illustrate the development of macro and add-in with two simple examples. By macro us to record some of the duplicates in VS, we can run them multiple times to save time and maintain a good mood; through add-in, we can add new functionality to vs by ourselves, extending vs means expanding ourselves. VS 2008 expanded Way at

Summer, is a "virus" season, computer viruses are no exception, especially the risk factor is very large Doc virus (virus macro virus) is the use of IE browser access to the network on the Doc page, will also be inexplicably to "black" a. So what is doc exactly a virus ah, it is how black their own baby computer it? Now let's take a look at what the doc virus looks like. Macro virus, it is a special virus

Replacing macros with Inline: 1. inline debuggable; 2. You can perform type security check or automatic type conversion; 3. Accessible member variables. In addition, the member functions defined in the class declaration are automatically converted to inline functions. Article (1) Inline functions and macro definitionsIn C, a commonly used pre-processing statement # define is used to replace a function definition. For example:# Define max (A, B) (a)> (

Macros: macro, preset text substitution mode:A macro is an abstract concept (abstraction) that replaces certain text patterns based on some of the predefined rules of a column, whereas an explanation or compiler automatically replaces this pattern when it encounters a macro. Similarly, Zabbix saves the preset text pattern based on a
