audacity macro

This article only provides an idea, a kind of personal experience, designed to use a very vulgar and relatively grounded way, prompting cainiao, why, and how to introduce debug Macros in C language programs, develop and maintain good habits. Asked about debugging during the interview, I said: Early printf, later gdb, Q: How does printf work? Directly change the program? Answer: Yes ~! He didn't mention it. I also know that the debug macro should be u

First, demand-oriented, small projects, code is not many, version is quite a lot ... You plan to use a macro to control the switch options, and then pass a long string #if #elif ... #endif To control the build version number, but also according to compatibility and minor changes to do the level three version number .... So we need a version number splicing, obviously, it should be the compile time can be done. --------Demand is complete-------- The C-

The function of the # in a macro is to string the macro arguments that follow it (stringizing operator), simply by adding a double quote to the left and right of the macro variable it refers to.The following two statements are equivalent, as defined #define STRING (x) #x .char *pchar = "Hello";Char *pchar = STRING (hello);And a #@ is a single quote (Charizing Ope

1. functions and macros(1) Macros are expanded by direct substitution of preprocessing , and the compiler does not know the existence of macros(2) A function is an entity compiled directly by the compiler , and the invocation behavior is determined by the compiler(3) Multiple use of macros will result in an increase in the volume of the final executable program(4) The function is jump execution, in memory only one copy function body exists(5) The efficiency of the

This article will use recorded macros in Word to solve the problem of garbled text formatting on a copy-and-paste network.

The original Article is here Variable Parameter macro Macros can receive variable parameter lists, just like functions. The syntax for defining variable parameters is similar to that for a function. Here is an example: # Define eprintf (...) fprintf (stderr, _ va_args __) These macros are called Variable Parameter macros. When a macro is called, all symbols after the first named parameter, inc

Token paste OPERATOR ):## 1. To put it simply, "#" is a separate connection method. Its function is to first separate and then force the connection. The separator is similar to a space. We know that in the general macro definition, the Preprocessor generally uses spacesThe interpretation component segment flag. If each segment is compared with the previous one, it will be replaced. But the result is,There are some spaces between the replaced segments.

Compare the similarities and differences between parameters with macros and functions From http://blog.csdn.net/piaojun_pj/article/details/5932639 The compiler processes Macros in the pre-compilation phase of the program. It mainly replaces Macros in the source file with pre-compilation commands. 1. Macros will be replaced simply when the compiler compiles the source code, without any logic detection, that is, simple code replication. 2. When macro
