一段时间以来，我一直试图重新开始编码，所以我想我应该从一些简单的 SDL 开始，现在，没有文件 i/o，编译正常，但是当我输入 stdio 代码时，它开始抛出错误。这个我不确定，我没有看到代码本身有任何问题，但是，就像我说的，我还是个新手，我想我来这里是为了找一个有更多经验的人这种东西看看吧。

我想我的问题可以归结为:“为什么这个不能在 Microsoft 的 Visual C++ 2008 Express 下编译？”

我已将错误日志附在代码片段的底部。在此先感谢您的帮助。

#include "SDL/SDL.h"
#include "stdio.h"

int main(int argc, char *argv[])
{
    FILE *stderr;
    FILE *stdout; 

    stderr = fopen("stderr", "wb");
    stdout = fopen("stdout", "wb");

    SDL_Init(SDL_INIT_EVERYTHING);
    fprintf(stdout, "SDL INITIALIZED SUCCESSFULLY\n");
    SDL_Quit();
    fprintf(stderr, "SDL QUIT.\n");

    fclose(stderr);
    fclose(stdout);

    return 0;
}

报告的实际错误:

最佳答案

#include "SDL/SDL.h"
#include "stdio.h"

int main(int argc, char *argv[])
{
    FILE *stderr; //Invalid names. These are already defined by stdio.h.
    FILE *stdout; //You can't use them (portably anyway).

    stderr = fopen("stderr", "wb"); //I'm assuming you actually want files
    stdout = fopen("stdout", "wb"); //called "stderror" and "stdout".

    SDL_Init(SDL_INIT_EVERYTHING);
    fprintf(stdout, "SDL INITIALIZED SUCCESSFULLY\n");
    SDL_Quit();
    fprintf(stderr, "SDL QUIT.\n");

    fclose(stderr);
    fclose(stdout);

    return 0;
}

尝试将名称 stderr 和 stdout 更改为其他名称。我怀疑编译器在提示，因为这些已经在 C 库的其他地方定义了。
