本程序是复数类的继承

复数CPP文件


#include <iostream>
using namespace std;

#include "complex.h"

complex::complex()
{
	//Real=0;
	realnum();
	Imag=0;
}

complex::complex(double real,double imag)
{
	//Real=real;
	realnum(Real);
	Imag=imag;
}


complex::addc(complex c1,complex c2)
{
	//Real=c1.Real+c2.Real;
	add(c1,c2);
	Imag=c1.Imag+c2.Imag;
}

void complex::showc()
{
	char s='+';
	if(Imag<0)s='\0';
    cout<<"    这个复数是:"<<Real<<s<<Imag<<"i"<<endl;
}

void complex::setcom()
{
	n++;
	cout<<"复数"<<n<<"实部是:";
	cin>>Real;
    cout<<"虚部是:";
	cin>>Imag;
	//cout<<endl;
}
