I'm new to C and C++ programming and I've chosen MS VC++ V6.0 for my
work. The question that I have is:

How do I declare complex variables, arrays and functions in C++ V6.0?
I understand that I need to include the appropriate header file in my source code. I do this using:

#include <complex>



Everything that I've tried has failed.
By the way, at this time I'm just trying to implement a simple console
program.
