c++第十次作业（谭浩强c++程序设计第三版P327习题）

3.重载+运算符完成复数相加  和  复数与整数相加

#include 
using namespace std;

class Complex{
	private:
		int real;
		int imag;
	public:
		Complex(int r,int i):real(r),imag(r){}
		friend Complex operator+(Complex &a1,Complex &a2);
		friend Complex operator+(Complex &a1,int b);
		void display(Complex &a);
};
Complex operator+(Complex &a1,Complex &a2) 
{
	Complex a(0,0);
	a.real =a1.real +a2.real;
	a.imag =a1.imag +a2.imag;
	return a;
}
Complex operator+(Complex &a1,int b)
{
	Complex a(0,0);
	a.real =a1.real+b;
	a.imag=a1.imag;
	return a;
}
void Complex::display(Complex &a) 
{
	cout<<"虚部为："<
