Yeah, I screwed that up.  But it doesn't make any difference to the problem. 
This should be correct though.

#include <stdio.h>
#include <complex.h>

int main(int argc, char *argv[]) {

 double data[6] = {1.0, 2.0, 3.0, 4.0, 5.0, 6.0},*d;
 double complex ddata[6], *c, s = 3.0;
 int i;

 d=data;
 c=ddata;
 for (i = 0; i<6; i++) {
  printf("c(%p), d(%p)=%f\n",c,d,*d);
  *c++ = *d++ * s;
 }
 return 0;
}
