我一直在尝试重新编码，所以我想我会从一些简单的 SDL 开始，现在，没有文件 i/o，这编译得很好，但是当我输入 stdio 代码时，它开始了抛出错误。这个我不确定，我看不出代码本身有什么问题，但是，就像我说的，我还不如成为一个新手，我想我会来这里找一个有更多经验的人这种东西就看吧。

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

我在代码片段的底部附上了错误日志。提前感谢您的帮助。

#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：

#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。我怀疑编译器在抱怨，因为这些已经在 C 库的其他地方定义了。

  1. 您不需要声明、打开或关闭stdin，stdout或者stderr，这已经在stdio.
  2. 如果您使用的是 C++，为什么不iostream呢？
