Can someone please help me correct the problems in the following code that enables operations on complex numbers and enables input and output of complex numbers through overloaded << and >> operators and overloads the multiplication *, division /, == and != operators. I am getting the following errors when trying to run the program:

'COMPLEX_H': macro is not defined or definition is different after precompiled header use,

'operator>>' must return a value,

header stop cannot be in a macro,

the #endif for this directive is missing,

unexpected tokens following preprocessor directive - expected newline.

#ifndef COMPLEX_H

#define COMPLEX_H

#include "stdafx.h""

#include "

using namespace std;

class Complex {

private:

double real;

double imaginary;

public:

Complex(double r = 0.0, double i = 0.0)

{

real = r;

imaginary = i;

}

Complex operator*(Complex c2)

{

Complex temp;

temp.real = real * c2.real;

temp.imaginary = imaginary * c2.imaginary;

return temp;

}

Complex operator/(Complex c2)

{

Complex temp;

temp.real = ((real * c2.real) + (imaginary * c2.imaginary)) / ((c2.real * c2.real) + (c2.imaginary * c2.imaginary));

temp.imaginary = ((real * c2.real) - (imaginary * c2.imaginary)) / ((c2.real * c2.real) + (c2.imaginary * c2.imaginary));

return temp;

}

bool operator==(Complex &c) {

return real == c.real && imaginary == c.imaginary;

}

bool operator!=(Complex &c) {

return !(real == c.real && imaginary == c.imaginary);

}

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

friend istream &operator>>(istream &in, Complex &c);

};

ostream &operator<<(ostream &out, Complex &c)

{

if (c.imaginary < 0)

out << "(" << c.real << c.imaginary << "i )";

else

out << "(" << c.real << "+" << c.imaginary << "i )";

return out;

}

istream &operator>>(istream &in, Complex &c) {

in >> c.real >> c.imaginary;

}
