complex.cpp

it can help you use C++ program we

#include <iostream >
using namespace std;

class CComplex
{
private:
	double	real;
	double	image;

public:
	CComplex()					//不带参数的构造函数，即缺省构造函数
	{
		real = 0.0; 
		image = 0.0; 
	}

	CComplex(double rv)			//带一个参数的构造函数
	{
		real = rv;
		image = 0.0;
	}

	CComplex(double rv,double iv)	//带两个参数的构造函数
	{
		real = rv; 
		image = iv;
	}
	
	void print()					//打印输出复数的实部和虚部
	{
		cout << "(" << real <<"+"<<image<< "i)"<<endl;
	}
};


//下面的main函数为测试使用
int main( )
{
	CComplex	z1,z2(2),z3(2,3);
	z1.print( );
	z2.print( );
	z3.print( );

	return 0;
}
