Ios7: Random Talk#defineMacro definition#define宏定义在C系开发中可以说占有举足轻重的作用. The underlying framework does not have to say, in order to compile optimization and convenience, as well as cross-platform capabilities, macros are heavily used, it can be said that the bottom of development left define will be unable to move. When developing at a higher level, we put more emphasis on business logic and seem to have little use and reliance on macros. But the benefits of using

Word2007 prompt Error "This error is usually caused by macro security settings" Every time you run Word, a prompt window appears-"This error is usually caused by macro security settings." If you know that the macro is from a source that you trust, you can change the

I. OverviewZabbix supports many macros that are used in various situations. A macro is a variable that is identified by the following special syntax: macroUsing macros effectively saves you time and makes Zabbix more efficient.In a typical use, a macro can be used in a template. Therefore, the template's trigger may be named ' {host.name} ' mysql{#MYSQLPORT} port is down, please check! ”。When this template

Original address: http://blog.csdn.net/cp1300/article/details/7773239 when we write a program, we always add more or less statements such as printf to output debug information. But the printf statement has a very inconvenient place is when we need to publish a program to be a one to delete these statements, and once again, when the need to debug, these statements have to add, which brings us a great inconvenience, wasted a lot of our time, but also caused the inefficiency of debugging. Therefore

The execution process of inline functions is similar to the macro definition with parameters, but the processing of parameters is different. Macro definitions with parameters are not calculated, but replaced directly. Inline functions are functions first, which means that many of the functions are suitable for inline functions. That is, inline functions evaluate the parameter expressions first, Then pass th

The execution of an inline function is similar to a parameter macro definition, but the parameters are handled differently. The macro definition with parameters does not operate on the parameter, but instead, the inline function is the function, which means that many properties of the function are applicable to the inline function, that is, the inline function evaluates the argument expression first, and th

How to place macro (memory,PLL,Adc,dac, special IO, etc.)When the overall placement, should consider:1) Pll,adc,dac to be placed on the side as required by IO2) macro and IO relationship, the same function to close3) According to the inside of the chip data flow, in order to display4) If it is iolimit design, in addition to PLL/ADC/DAC and other macro connected w

In C language programming, for a relatively large project, the use of the library will be more, if the design of a slight negligence, it may create a macro-defined conflict. An example of a project is that the two header file defines "isspace (CH)", and the two macro definitions are inconsistent, causing the entire project to fail to compile. The solution to this problem is to undefine the

Introduction to preprocessing Directives1.C language before compiling the source program, some special pre-processing instructions (such as the previous use of the # include directive) to produce a new source program (this process is called the compilation preprocessing), and then the usual compilation2. In order to differentiate between preprocessing directives and generic C statements, all preprocessor directives begin with the sign "#" and end without semicolons3. A preprocessing instruction

In C ++, although using macros is not recommended, macros often provide us with some convenience, and there are indeed a large number of Macros in the existing code. Some people think that macros are the root cause of errors, because some strange code may appear after macros are expanded, so this article will summarize some methods to view the code after macros are expanded. 1. in Visual Studio 2005, select project Properties> Configuration Properties> C/C ++> Preprocessor, and select generate

Many C ++ books advise us that C language macros are the first of all evil, but things are not as bad as we think, just like Goto. MacroA major role is to automatically generate code for us. If the template can generate various types of code (type replacement) for us ),In fact, macros can generate new Code (replacement and addition of symbols) on the symbols ). You can find some macro Syntax problems on Google. Believe me, you do not know as much abou

The macro in the forum. C/C ++ summarizes various compilation commands in the source code of the C program. These commands are called preprocessing commands. Although they are not actually part of the C language, they extend the C programming environment. This section describes how to use preprocessing programs and annotations to simplify the program development process and improve the readability of the program. The C language Preprocessing Program d

Write a good-looking macro definition in C language. Using macro definition can prevent errors, improve portability, readability, and convenience. The following lists some macro definitions commonly used in mature software ......1. prevent a header file from being repeatedly contained# Ifndef comdef_h# Define comdef_h// Header file content# Endif2. redefine some

0. PrefaceFrom the beginning of learning C language began to contact Makefile, consulted a lot of makefile information but always feel no real master makefile, if you write a makefile always feel very laborious. So deliberately using the blog to summarize the relevant knowledge of makefile, through examples to illustrate the specific use of makefile. The example says that makefile roughly divides into 4 parts 1. Only a single C file 2. Contains multiple C files 3. Need to include header file pa

In GNU C, a macro can accept a variable number of arguments, just like a function__va_args__ can be regarded as the ... Assign a value to the macro // Note you can't call ABC () #include #include #define ABC (...) printf (__va_args__) /* void ABC (...) {//printf (__va_args__);} */ int Main () {ABC ( " %s\n , " hello ); return 0 ;} Note that the m
