What's wrong with #include <complex> exactly?

(1) Is "complex" file on your include path?
(2) Is "complex.h" file on your include path?
(3) Does using "#include <complex> produce compile errors? Note that "complex" is a template nowadays. You need to declare "complex<double> somecomplex". If you need the "old way" when "complex" was a class then #include complex.h and use "double complex somecomplex;"

when i try include the complex.h file it gives me error no such file.

Yes i did. And tried to implement it but when ever i include the complex.h file it giver error no such file

it gives me error that no such file. I will look weather it is in my include path or not
