C complex number usage

[Bruce Labitt]

Hopefully a simple question.  I'm trying to write a C program that uses 
complex numbers.  (I'm a  "C" illiterate.  Just wrote my second 
program...)  Reading the header file complex.h hasn't helped too much.  
Can someone give me a hint on how to "fix" this?  Most of the references 
on C are *ancient* (like me) and don't cover the C99 complex number 
stuff.  Please ignore my awful coding style.

#include <math.h>
#include <time.h>
#include <complex>
#include <fftw3.h>

double gaussrand();
int N;   /* length of FFT */
int ii;  /* index */
N = 1024;
double _Complex g[N];
double mymean, mystdev;
double _Complex I;

// assign mymean and mystdev here...

// Create array of complex random numbers
    for (ii=0; ii<N; ii++)
    {
        g[ii] = mymean*(1+I) + mystdev*gaussrand() + I * mystdev * 
gaussrand();
    }
// End complex random number generation

The compiler barfs on the g[ii] assignment...
41 C:\Dev-Cpp\myproj\main_tb_fftw.cpp cannot convert `double 
__complex__[((unsigned int)((int)N))]' to `double (*)[2]' in assignment

Hopefully someone can point me in the write direction.  TIA.
