C++复数类的用法

#include<iostream>
#include<string>
#include<complex>//复数类头文件
using namespace std;
 
int main()
{
	cout << "复数类对象定义:" << endl;
	cout<<endl;
	double x = 1.0;
	double y = 1.0;
	complex<double> Z1;//默认为0+0i
	complex<double> Z2(-1, 1);//-1+1i
	complex<double> Z3(x, y);//x+yi
	complex<double> Z4 = 2.0;//默认为2.0+0i
	complex<double> Z5 = Z4 + complex<double>(2, 1);
	complex<double> Z6 = Z1 + Z2;
	
	cout << "Z1=" << Z1 << endl;
	cout << "Z2=" << Z2 << endl;
	cout << "Z3=" << Z3 << endl;
	cout << "Z4=" << Z4 << endl;
	cout << "Z5=" << Z5 << endl;
	cout << "Z6=" << Z6 << endl;
	cout <<endl;
	
	cout<<"复数的运算:"<<endl;
	cout<<endl;
	cout<<"real()函数获取复数的实部"<<endl;
	cout<<"real(Z2)="<<real(Z2)<<endl;
	cout<<"imag()函数获取复数的虚部"<<endl;
	cout<<"imag(Z2)="<<imag(Z2)<<endl;
	cout<<"conj()获取复数的共轭复数"<<endl;
	cout<<"conj(Z2)="<<conj(Z2)<<endl;
