Compling errors

[Warren Hoskins]

I'm working on a program, overloading operators, when I compile the program together it works, however when I separate it into the various files such as the .h and the .cpp I'm getting a lot of error messages. Can you offer any suggestions.

Here's the code:

//#include "complex.h"//implementation file
#include <iostream>
//#include<math.h>  
using namespace std;

class Complex
{
	public:
		Complex(double, double);
		Complex();
		Complex(double);   
		friend ostream& operator <<(ostream& out, const Complex& c);
		friend istream& operator >>(istream& in, Complex& c);
		friend const Complex operator *(const Complex& l, const Complex& r);
		friend const Complex operator -(const Complex& l, const Complex& r);
		friend const Complex operator +(const Complex& l, const Complex& r);
		friend bool operator ==(const Complex& l, const Complex& r);
	private:
		 double real, imag;
};

// define constructor
Complex::Complex( double r, double i )
{
    real = r; imag = i;
}

Complex::Complex()
{
	real = 0;
	imag = 0;
}

Complex::Complex(double realPart ) //constructor that takes a single parameter
{
	realPart = 0;
	int i = 1;
}

ostream& operator <<(ostream& out, const Complex& c)
{
	out << c.real << "+" << c.imag << "i";
	return out;
}

istream& operator >>(istream& in, Complex& c)
{
	char op;
	char i;
	in >> c.real >> op >> c.imag >> i; 
	
	return in;
}
 
// define overloaded + (plus) operator
const Complex operator +(const Complex& l, const Complex& r) 
{
    Complex result;
    result.real = (l.real + r.real);
    result.imag = (l.imag + r.imag);
	
    return result;
}

const Complex operator -(const Complex& l, const Complex& r) 
{
      Complex result;
      result.real = (l.real - r.real);
      result.imag = (l.imag - r.imag);
      return result;
}

const Complex operator *(const Complex& l, const Complex& r) 
{
     
      int a = (l.real*r.real - l.imag*r.imag);
      int b = (l.imag*r.real + l.real*r.imag);
	  Complex result(a,b);
      return result;
}

bool operator ==(const Complex& l, const Complex& r)
{
	return ((l.real == r.real) && (l.imag == r.imag));
}


 
int main()
{ 
	Complex a(4,5), b(6,5);
	double realPart = 0;
	Complex i(0,1);
	cout << "First complex number is " << a << endl;
	cout << "Second complex number is " << b << endl << endl;
	cout << "Testing constant i..."<<endl; 
	cout << "The value of our constant i is: " << i << endl <<endl;
	cout << "Enter 2 new complex numbers in the form a+bi(with no spaces):" << endl;
	cin >> a >> b;
	cout << endl;
	
    
	cout << a << " + " << b <<" = "<< a + b<< endl;
	cout << a << " - " << b <<" = "<< a - b<< endl;
	cout << a << " * " << b <<" = "<< a * b<< endl << endl;
	cout << "Testing equality operator..." << endl;
	if (a == b)
		cout << a << " is equal to " << b << endl;
	else
		cout << a << " is not equal to " << b << endl;
	return 0;
	
}

Here are the error messages:

Welcome to theScripts,

I am taking the liberty of moving this thread to the C forum, where I'm sure the experts will be more than willing to offer some advice....

What is the name of the files you are saving this code in? You may be trying to open a file that doesn't exist.
