complex类的设计实现

#include <iostream> 
#include <cmath>
using namespace std;
class Complex{
    public:Complex(double real0=0,double imaginary0=0);
    Complex(Complex &a);
    void add(Complex b);
    void show();
    double mod();
    private:
        double real;
        double imaginary;
};
Complex::Complex(double real0,double imaginary0){
    real=real0;
    imaginary=imaginary0;
}
Complex::Complex(Complex &a){
    real=a.real;
    imaginary=a.imaginary;
}
void Complex::add(Complex b){
    real+=b.real;
    imaginary+=b.imaginary;
}
void Complex::show(){
    cout<<real<<"+"<<imaginary<<"i"<<endl;
}
double Complex::mod(){
    double m;
    m=sqrt(real*real+imaginary*imaginary);
    return m;
}
int main()
{Complex c1(3,5);
cout<<"c1 = ";
c1.show();
cout<<"|c1| = " <<c1.mod() <<endl;
 Complex c2(4.5); 
 cout<<"c2= ";
 c2.show();
 cout<<"|c2| = " <<c2.mod() <<endl;
 Complex c3(c1);
 c1.add(c2);
 c1.show();
 cout<<c1.mod()<<endl; 
}

总结：对这个复制构造函数还是有些不太理解，实现起来的时候还是有点小困难的，通过同学的帮助还是顺利做出来了。希望自己接下来能继续好好理解摸透每一个程序背后的意义，做到深入理解。
