class Complex{
    float a, b;
    public:
    Complex(): a(0), b(0) {}
    Complex(float x, float y): a(x), b(y){}
    void display(){
        cout<<this->a<<" + "<<this->b<<"i"<<endl;
    }
    Complex operator++(){
        this->a++;
        this->b++;
        return *this;
    }
    Complex operator++(int){
        this->a++;
        this->b++;
        return *this;
    }
};
int main(){
    Complex complex(1, 1);
    complex.display();
    complex++;
    complex.display();
    ++complex;
    complex.display();
    return 0;
