. Extract a bunch of header files that almost all CPP contains, put them in one place, such as stdafx.h, and compile the project first, compiling the stdafx.cpp, then generate an intermediate file:. pch, files that all CPP can use. You can see if you have a. pch file in the debug/release of the directory where your project is located? This is the precompiled header after compilation. Maybe you've seen the.

Role of stdafx. h header file standard application fram extendWithout a function library, some environment parameters are defined so that the compiled program can run in a 32-bit operating system environment.The include files for Windows and MFC are very large. Even if there is a fast processing program, it takes quite a long time to compile the program. Since each. cpp file contains the same include file, it is silly to process these files repeatedly for each. cpp file.To avoid this waste, Appw
I. Why precompiled header files:Concepts of precompiled headers:
The so-called pre-compilation header is to pre-compile the part of the code in a project and put it in a file (usually. pch Extension). This file is called the precompiled header file. The pre-compiled code can be any C/C ++ code, or even an inline function, however, it must be stable and won't be changed frequently during project development. If the code is modified, re-compile the pre-

Generally, you need to add import header files to process macro files. You can define this macro in this file later and do not need to import header files.

Pre-compiled header file: The most common application scenario is the stdafx. h file, which contains common header files, such as Windows. H, cstdio, string, and other. cpp files to include the stdafx. h header files. Although stdafx. H is included by multiple. cpp files, stdafx. H is compiled only once. This accelerates compilation.Stdafx. cpp is used to generate pre-compiled files. There is only one line of code in stdafx. cpp # include "stdafx. H". Compiling stdafx. cpp will generate a.
