How do you read scanf until EOF in C?

I have this but once it reaches the supposed EOF it just repeats the loop and scanf again.

int main(void)
{
        char words[16];

        while(scanf("%15s", words) == 1)
           printf("%s\n", words);

        return 0;
}

Man, if you are using Windows, EOF is not reached by pressing enter, but by pressing Crtl+Z at the console. This will print "^Z", an indicator of EOF. The behavior of functions when reading this (the EOF or Crtl+Z):

Function Output
scanf(...) EOF
gets(<variable>) NULL
feof(stdin) 1
getchar() EOF

I guess best way to do this is ...

int main()
{
    char str[100];
    scanf("[^EOF]",str);
    printf("%s",str);
    return 0;     
}
