I don't know.

Yes.
I suggest you should write it like this:

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
    int nc; /* use integer instead of double for counting */
    for(nc=0;getchar()!=EOF;nc++)
      ;
    printf("\n");
    printf("%d\n",nc); /* print as integer */
    
    system("PAUSE");
    return 0;
}

Well,  the  printf()  function  executes, but it seems that it doesn't
print  out  anything  until  you print a newline ('\n') first. I don't
exactly know why this is needed.
If  you  try  the  original code (without the first '\n') with a file,
you'll notice that it works. It seems that printf() thinks it is still
at  EOF  of  stdout,  until  you  print '\n'. (which is a foolishness,
because  you  read from stdin, and stdin reaches EOF!!!) But this only
happens, when you type from the console. When you use a file, it works
normally. (for example: count.exe < file.txt)
