I need a huge help. I have problems with the library <complex.h> I'm compiling with CC in a Sun system and when I compile it don't recognize the complex numbers what do I have to do?
You can start by including <complex> instead of <complex.h>.
I don't know why so many are using .h headers. It is not correct C++! I don't know about the Sun system, but at least with GCC using .h in the std headers can cause trouble.
