As a newbie programmer, i sometimes encouter the failure that the header files include each other. This article will illustrate why and how to solve this probleam Why we need header file (1) It speeds up compile time.(2) It keeps your code more organized.(3) It allows you to separate...
The header file should (and will) have a #ifndef wrapper to prevent problems with this (the problem is actually with cyclic inclusion - you include -> foo.h includes bar.h bar.h includes foo.h). In your case the "duplicate" inclusion is actually needed (for function prototypes, structu...
More typically though, the names defined in a translation unit that other translation units can use are declared in a header file, your helper.h. The using translation unit uses the "canned" declarations in the header file by #include-ing it. There is no magic here; an include directive s...

Another great advantage offered by conditional inclusion statements (preprocessor directives) is 'once~only~include~files'. Very often, one header file includes another. It can easily result that a certain header file is included more than once. This may lead to errors, if the header file ...
If any of these options is used, then the linker(链接器) is not run, and object file names should not be used as arguments. SeeOverall Options. 三、警告信息 四、具体编译示例 源码文件 main.c #include<stdio.h>intmain() {printf("Hello Wolrd!");return0; } ...
include:包含头文件的目录。这里有两个子目录,一个是static_lib,包含静态库的头文件StaticLibHeader.h;另一个是dynamic_lib,包含动态库的头文件DynamicLibHeader.h。 libs:存放静态库和动态库的目录。这里有两个子目录:static和dynamic。static目录中包含一个名为libStatic.lib的静态库,dynamic目录中包含一个名为lib...
But, if you import by using the command-line utility, you can import several C header files in each import operation. If your C header file needs any other header files for a successful compilation, you must provide these and specify their location, because a compil...
