/home/CBP/score. The c in Windows have this path and the file?

 if ((fd=fopen ("/home/CBP/score. C ", "rw")) & lt; 0 {
Perror (" open "); 
exit(1); 
}

This has a problem, fd should be compared and NULL,
As this place did not perform to the exit, in fact, because can't find file fd is NULL, but the NULL & lt; 0 does not satisfy, so there is no exit, directly behind the fd appear mistake,

Solution:

 if ((fd=fopen ("/home/CBP/score. C ", "rw"))==NULL) {
Perror (" open "); 
exit(1); 
}

Under the Windows a try, see if I can run directly perror and exit (no/home/directory under Windows)

I need to know the difference between Windows and LINUX system, can't get the code to use, because there will be a transplant problem ~
