C++复数乘法算不出回来

Question

#include<iostream>
using namespace std;

class Complex
{
public:
    int real;
    int imaginary;
public:
    Complex();
    Complex(int r, int i) :real(r),imaginary(i){};
    void Output();
};

Complex::Complex()
{

}

void Plus(Complex &c1, Complex &c2, Complex &c3)
{
    Complex k;
    k.real = c1.real + c2.real + c3.real;
    k.imaginary = c1.imaginary + c2.imaginary + c3.imaginary;
    k.Output();
}

void Multiply(Complex &c1, Complex &c2, Complex &c3)
{
    Complex a,b;
    a.real = c1.real * c2.real - c1.imaginary * c2.imaginary;
    a.imaginary = c1.imaginary * c2.real + c1.real * c2.imaginary;
    b.real = a.real*c3.real - a.imaginary*c3.imaginary;
    b.imaginary = a.imaginary*c3.real + a.real*c3.imaginary;
    b.Output();
}

void Complex::Output()
{
    if (imaginary > 0)
        cout << real << "+" << imaginary << "i" << endl;
    else
        cout << real << imaginary << "i" << endl;
}

int main()
{
    int r1, r2, r3, i1, i2, i3;
    cin >> r1 >> r2 >> r3 >> i1 >> i2 >> i3;
    Complex c1(r1, i1);
    Complex c2(r2, i2);
    Complex c3(r3, i3);
    Plus(c1, c2, c3);
    Multiply(c1, c2, c3);
    return 0;
