The content of my program are the following:

void filecopy(FILE *ifp,FILE *ofp)
{int c;
while ((c=getc(ifp))!=EOF)
putc(c,ofp);
}
when I input command lines,for example:cat f:\test\1.cpp (windows xp
is installed in my computer)
the output are :cat f:\test\1.cpp
The angrument which is f:\test\1.cpp donot have work,and output is cat
f:\test\1.cpp
I know the program have no problem.
But I can't run the program corretly?
What should I do?
Call it correctly. The program is correct. It would be too much to say
that it has no problems, since it is horribly formatted, but it is at
least correct. I can compile it and run it, and it works both with stdin
and with a file I specify. Are you absolutely sure the filename you give
it is correct? Try the same command with type instead of cat, and see if
that does show up.
