textexpander macros

Explanation of C language # macros such as ifdef These macros are used for Conditional compilation. Generally, all the rows in the source program are compiled. However, sometimes you want to compile a part of the content only when certain conditions are met, that is, to specify the compilation conditions for a part of the content. This is "Conditional compilation ". Sometimes, you want to compile a group of

I. Definition In Microsoft Visual Studio/vc98/include/windef. h of vc6.0, byte, word, DWORD are defined. Typedef unsigned long DWORD; Typedef unsigned char byte; Typedef unsigned short word; In Visual C ++ 6.0, the char type is 1 byte, the short type is 2 bytes, And the int and long types are both 4 bytes. Therefore, we can consider that byte and word, the variables defined by DWORD obtain 1-byte, 2-byte, and 4-byte memory respectively, which are consistent with the literal meanings of byte and

Va Function Definition and VA macro C language supports the VA function, which is an extension of C language. c ++ also supports the VA function, but it is not recommended in C ++.The polymorphism introduced by C ++ can also be used to implement functions with variable parameter numbers. However, C ++ has completed the reload function.It can only be a limited number of foreseeable parameters. In comparison, the VA function in C can define an infinite number.C ++ is powerless in this respect. The

Python Nmon Analyzer: keeps you away from excel macros Nginx's monitor, also known as "Nmon", is a good tool for monitoring, recording, and analyzing Linux/* nix system changes over time. Nmon was initially developed by IBM and open-source in the summer of 2009. Today, Nmon is available on all Linux platforms and architectures. It provides a command line-based Real-time visual Report of the current system statistics, including CPU, RAM, network and d

contains the tchar. h header file, _ tcslen is defined as wcslen: # DEFINE _ tcslen wcslenIf Unicode is not defined, _ tcslen is defined as strlen: # DEFINE _ tcslen strlenAnd so on. Tchar. H also uses a new data type tchar to solve the problem of two character data types. If _ Unicode identifier is defined, tchar is wchar_t: Typedef wchar_t tchar;Otherwise, tchar is Char: Typedef char tchar;Now we will discuss the question of L in string text. If _ Unicode identifier is defined, a macro called

ReprintedIn C language, how to use macros (macro) in macro C (and C ++) belongs to the scope of compiler preprocessing and to the concept of compilation period (rather than runtime ). The following briefly summarizes the frequently encountered macro usage problems.About # And ## In the macro of C language, the # function is to stringize the macro parameters following it (stringfication). Simply put, it is referencedMacro variableAfter replacement, add

Excel 2003 This afternoon, I want to figure out the tools used to load Macros in the following Excel files and select all the macros.This is good. Turn off the Excel file and open it again. The Excel file will be dynamic and unavailable several times in a row. I didn't know at first that I had loaded many macros and thought I had a problem with my system (maybe it was a problem)However, when Excel was ope

Mixed macros are primarily used to pass parameters, but when Sass compiles the same mixed macro, the same styles are not merged. Generates redundant code.Inheritance is primarily used where arguments are not passed, and the base class already exists, and the same style is merged after compilation, not enough: the declared base class generates code regardless of whether the base class is called.Placeholders are similar to inheritance, but placeholders

Let's talk about what we'll mention in this article: ##,__va_args__, __file__, __line__, __function__, etc.Macro variables:To give an example, you'll use these macros: #define myprintf (...) printk ("[Lch]:file:%s, line:%d, function:%s," \ __va_args__, __file__, __ line__, __function__); The purpose of the #define here is to replace myprintf () with the contents of the following large string, in parentheses ... The contents of the __va_a

increase the amount of code, and the use of macro definitions in terms of code size and speed is better than the function, second, the function parameters must be declared as a specific type, so it can only be used on the type of the appropriate expression, if we want to compare the size of two floating-point You'll have to write a comparison function specifically for floating-point types. Third, the code structure is relatively simple, the use of macros
