Question: Representing complex numbers in C

[lim at ecs.umass.edu]

Hi,

I'd appreciated it if anyone out there can help me out with this problem. It 
concerns representation of complex numbers in C. I understand that Fortran has 
a data type COMPLEX that allows complex variables to be treated like any int, 
float, or double. I need to do the following in C:

COMPLEX x, y, z;
z = x + y;
etc.

The following won't work, obviously...

struct
{
 double real;
 double imaginary;
}
COMPLEX;

Thanks in advance.
