C++ Complex Number Operator Overloading

I'm trying to overload the >> and << operators for use in a complex number class. For some reason my << and >> functions cannot access the real and imaginary parts of the complex objects even though I've made them friends of the class.

Complex.h:

#ifndef COMPLEX_H
#define COMPLEX_H

class Complex
{

friend std::ostream &operator<<(std::ostream &out, const Complex &c);
friend std::istream &operator>>(std::istream &, Complex &);

public:
     explicit Complex(double = 0.0, double = 0.0); // constructor
     Complex operator+(const Complex &) const;
     Complex operator-(const Complex &) const;

#endif

Complex.cpp:

#include "stdafx.h"
#include "Complex.h"
#include <iostream>
using namespace std;

istream &operator>>(istream &input, Complex &complex) // input
{
     cout << "enter real part:\n";
     input >> complex.real;
     cout << "enter imag part: \n";
     input >> complex.imaginary;
     return input;
}

std::ostream &operator<<(std::ostream &out, Complex c)     //output
{
     out<<"real part: "<<c.real<<"\n";
     out<<"imag part: "<<c.imag<<"\n";
     return out;
}

You didn't friend the same function you defined. You friended the first, and defined the second:

friend std::ostream &operator<<(std::ostream &out, const Complex &c);
       std::ostream &operator<<(std::ostream &out,       Complex  c)

Also, Is the member named imaginary or imag?

 input >> complex.imaginary;
 out<<"imag part: "<<c.imag<<"\n";
