help debug overloading <<

This is the first error of several. If you could explain to me what I am doing wrong here I can continue to debug the rest on my own
Here is the main code.

Code:

using namespace std;
#include "complexh.hpp"


int main()
{
    Complex a(3.0,4.0);  // instantiate a 
    Complex c;
    cout << "Enter a complex number (q to quit):\n";
    while (cin>>c) //                                                    error here

    { 
        cout << "c is " << c << endl;
        cout << "complex conjugate is " << ~c << '\n';
        cout << "a+c is "<< a+c << endl;
        cout << "a-c is "<< a-c << endl;
        cout << "a*c is "<< a*c << endl;
        cout << "2*c is "<< 2*c << endl;
        cout << "Enter a complex number (q to quit):\n"
    }
            
  cout << "Done!\n";
  system("PAUSE");	
  return 0;
}

Here is the prototype and function definiton

Code:

friend ostream & operator>>(ostream & os,const Complex & n);

ostream & operator>>(ostream & os,const Complex & n);
{
    cout << "real:";
    os >> n.rel;
    cout << endl;
    cout << "imaginary:";
    os >> n.imaginary;
    cout << endl;
    return os;
}

Here is an example where the book doesn't tell you everything.

I replaced the ostream object with istream and walla it works

By paying close attention to the compiler errors I figured it out.

Now I have one more problem given the imaginary number (3,4i)
subtracting (10,12 i) the output should be (-7,-8i) right?

The books output says (13,16i) who is correct me or the book?
