设计、定义并实现Complex类

 

#include<iostream>
#include<cmath>
using namespace std;
class Complex{
    public:
        Complex(double real1=0,double imaginary1=0);
        Complex(Complex &x);
        void add(Complex y);
        void show();
        double mod();
    private:
        double real;
        double imaginary;   
};
Complex::Complex(double real1,double imaginary1):real(real1),imaginary(imaginary1){};
Complex::Complex(Complex &x):real(x.real),imaginary(x.imaginary){};
void Complex::add(Complex y)
{  real=real+y.real;
   imaginary=imaginary+y.imaginary;
}
void Complex::show()
{  cout<<real<<"+"<<imaginary<<"i"<<endl;
}
double Complex::mod()
{  double s;
   s=sqrt(real*real+imaginary*imaginary);
   return s;
}
int main()
{ Complex c1(3,5);
  Complex c2(4.5);
  Complex c3(c1);
  c1.add(c2);
  c1.show();
  cout<<c1.mod()<<endl;
  return 0;
}

总结：对构造函数掌握不是很好，程序实现过程困难，通过此次complex实验加深了印象，需要花更多时间努力。
