VC++ 上的编译器问题2008 Express,看似正确的代码会引发错误

我已经尝试重新编码有一段时间了,所以我想我应该从一些简单的 SDL 开始,现在,没有文件 i/o,编译得很好,但是当我输入 stdio 代码时,它开始抛出错误。我不确定这一点,我没有看到代码本身有任何问题,但是,就像我说的,我也可能是一个新手,并且认为我应该来这里找一个有更多经验的人这种事就看看吧。

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

我已将错误日志附加在代码片段的底部。预先感谢您的任何帮助。

#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:

I've been trying to get back into coding for a while, so I figured I'd start with some simple SDL, now, without the file i/o, this compiles fine, but when I throw in the stdio code, it starts throwing errors. This I'm not sure about, I don't see any problem with the code itself, however, like I said, I might as well be a newbie, and figured I'd come here to get someone with a little more experience with this type of thing to look at it.

I guess my question boils down to: "Why doesn't this compile under Microsoft's Visual C++ 2008 Express?"

I've attached the error log at the bottom of the code snippet. Thanks in advance for any help.

#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;
}

#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。我怀疑编译器正在抱怨,因为这些已经在 C 库的其他地方定义了。

#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;
}

Try changing the names stderr and stdout to something else. I suspect the compiler is complaining because these are already defined elsewhere in the C library.

  1. 您无需声明、打开或关闭 stdinstdoutstderr,这些已在 stdio< 中为您完成/代码>。
  2. 如果您使用 C++,为什么不使用 iostream?
  1. You don't need to declare, open, or close stdin, stdout or stderr, that's already done for you in stdio.
  2. If you're using C++, why not iostream?
