课堂作业

#include<iostream>
using namespace std;
#include<cmath>

class Complex{
    public:
        Complex(double x=0,double y=0):real(x),imaginary(y){};
        Complex(const Complex &p):real(p.real),imaginary(p.imaginary) {};        
        void add(const Complex &p) ;
        void show()const;
        double mod()const;        
    private:
        double real;
        double imaginary;
};

void Complex::add(const Complex &p){
    real=p.real+real;
    imaginary=p.imaginary+imaginary;
}

void Complex::show()const{
    if(real!=0&&imaginary!=0)
    cout<<real<<"+"<<imaginary<<"i"<<endl;
    else if(real==0&&imaginary!=0)
    cout<<imaginary<<"i"<<endl;
    else if(real!=0&&imaginary==0)
    cout<<real<<endl;
}

double Complex::mod()const{
    return sqrt(real*real+imaginary*imaginary);
}
int main(){
    Complex c1(3,5);
    Complex c2(4.5);
    Complex c3(c1);
    c1.add(c2);
    c1.show();
    c2.show();
    cout<<c1.mod()<<endl;
    return 0;
}

 

 虽然这只是一个简单的小程序，但是我觉得要一下子，没有任何错误写出来也是需要细心的。
