通过输入两个复数

#include<iostream.h>
struct Complex
{int Real;
int Image;
};
void Complex1(Complex &a,Complex &b)
{cout<<"复数"<<a.Real<<'+'<<a.Image<<"i与复数"<<b.Real<<'+'<<b.Image<<"i的和为"<<a.Real+b.Real<<'+'<<a.Image+b.Image<<'i'<<endl;
}
void Complex2(Complex &a,Complex &b)
{cout<<"复数"<<a.Real<<'+'<<a.Image<<"i与复数"<<b.Real<<'+'<<b.Image<<"i的差为"<<a.Real-b.Real<<'+'<<a.Image-b.Image<<'i'<<endl;
}
void Complex3(Complex &a,Complex &b)
{cout<<"复数"<<a.Real<<'+'<<a.Image<<"i与复数"<<b.Real<<'+'<<b.Image<<"i的积为"<<a.Real*b.Real-a.Image*b.Image<<'+'<<a.Image*b.Real+a.Real*b.Image<<'i'<<endl;
}
void Complex4(Complex &a,Complex &b)
{cout<<"复数"<<a.Real<<'+'<<a.Image<<"i与复数"<<b.Real<<'+'<<b.Image<<"i的商为"<<(double)(a.Real*b.Real+a.Image*b.Image)/(b.Real*b.Real+b.Image*b.Image)<<'+'<<(double)(a.Image*b.Real-a.Real*b.Image)/(b.Real*b.Real+b.Image*b.Image)<<'i'<<endl;
