I have the following declarations FILE *fptr; FILE *optr; in algo.h I have the main in main.c which opens these files.
I\'ve got three files, add.h, add.cpp and test.cpp add.h creates a header for a class, and is nothing but skeletons for implementation later.
There is 3rd part he开发者_开发知识库ader file (header.h) define a structure a below, it can be passed compiling when treat it as C language. But we trying to include this file in CPP file, and the co
I\'m using pelles c. when I compile this code: #include <windows.h> #include <stdio.h> void main(void)
My C headers us开发者_开发百科ually resemble the following style to avoid multiple inclusion: #ifndef <FILENAME>_H
Suppose i am editing some large C++ source file, and i add a few lines of code that happen to use auto_ptr, like in the following example.
I have one .cpp file that includes a few header files. These header files may include other header files as well. Include guards are in place to prevent including the same file twice.
it seems like a lot of the code in boost are compiler-specific workarounds or different paths for different compilers (especially in components like mpl). My build time increases a lot when I use boos
What is the scope of a pragma directive? For开发者_如何学编程 example, if I say #pragma warning(disable: 4996) in a header file A that is included from a different file B, will that also disable all t
