// ComplexNums.cpp : Defines the entry point for the console application.
//
// This program calculates with complex numbers using addtion, subtraction and multiplication.

#include "stdafx.h"
#include <iostream>
#include <complex>
#include <string>
#include <iomanip>
using namespace std;

//Complex number calculator class
class Complex
{
public:
Complex(); //Constructs a complex object initialized to 0+0i
Complex(double r,double i); //Construcs an initialized complex object
// Input and output
void print(ostream& out); //prints a complex number to a stream in the form a+bi
void get(istream& in); //reads in a complex number from a stream in the form a+bi
//Operations
friend Complex multiply(const Complex& first, const Complex& second);
friend Complex plus(const Complex& first,const Complex& second);
//like multiply only adds
friend Complex minus(const Complex& first,const Complex& second);
//subtracts this minus second
private:
double real,imag;
};
// Beginning of main function
int _tmain(int argc, _TCHAR* argv[])
{...
