以下是完整的代码：

#include <iostream>
using namespace std;

/********* Begin *********/
class Complex {
    //复数类的声明
public:
    Complex(int x, int y);  // 构造函数
    Complex operator+(const Complex& c);  // 运算符重载：加法
    Complex operator-(const Complex& c);  // 运算符重载：减法
    Complex operator*(const Complex& c);  // 运算符重载：乘法
    void Print();  // 输出函数
private:
    int R;
    int V;
};

//复数类的定义
Complex::Complex(int x, int y) {
    R = x;
    V = y;
}

Complex Complex::operator+(const Complex& c) {
    Complex temp(R + c.R, V + c.V);
    return temp;
}

Complex Complex::operator-(const Complex& c) {
    Complex temp(R - c.R, V - c.V);
    return temp;
}

Complex Complex::operator*(const Complex& c) {
    Complex temp(R * c.R - V * c.V, R * c.V + V * c.R);
    return temp;
}

void Complex::Print() {
    cout << R << "+" << V << "i" << endl;
}
/********* End *********/

int main() {
    float a, b, c, d;
    cin >> a >> b >> c >> d;
    Complex c1(a, b), c2(c, d);
    cout << "c1 = ";
    c1.Print();
    cout << "c2 = ";
    c2.Print();
    cout << "c1 + c2 = ";
    (c1 + c2).Print();
    cout << "c1 - c2 = ";
    (c1 - c2).Print();
    cout << "c1 * c2 = ";
    (c1 * c2).Print();
}

注意，需要在类的定义中添加构造函数和运算符重载函数，同时输出时需要输出虚部的 "i"。
