Compiler issues on VC ++ 2008 Express, apparently correct code errors cause errors
I have been trying to get back to coding for a while, so I figured I would start with a simple SDL, now without the i / o file, this compiles fine, but when I throw the stdio code it starts throwing errors. This I am not sure, I do not see any problem with the code itself, however, as I said, I might be a beginner and figured I would come here to get someone who has 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 Visual C ++ 2008 Express?"
I have connected 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"

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".

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