C++ issue with + operator

[sturk]

My overload+ operator is not working properly. I am getting (0,0) for my output when it should have values instead. Would appreciate if anyone could help.

Correct output:
(4.2,12.6)

class fvector2D: public std::complex<float>
{ 
public:
fvector2D(float x=0, float y=0) : std::complex<float>(x, y)
{
 
} 
fvector2D(std::complex<float>) {} //conversion constructor
};
fvector2D operator+(const fvector2D& , const fvector2D&); 

fvector2D operator+(const fvector2D& lhs, const fvector2D& rhs)
{
	return static_cast<const std::complex<float> &>( lhs) + static_cast<const std::complex<float> &>(rhs);
}

int main()
{
fvector2D v(1, 4.1f);
fvector2D u(3.2f, 5.5f);
fvector2D w = u + v;
std::cout << w << std::endl;
}

fvector2D::fvector2D(std::complex<float>) doesn't do anything with its parameter. You probably meant to do

fvector2D(const std::complex<float> &other): std::complex<float>(other){}
