为什么我编的复数类不能执行除法运算了，能编译，不能生成

不能执行除法运算了  有生成错误   哪位大哥能帮帮我哈哈！

#include<iostream>
#include<cassert>
using namespace std;
class Complex
{
private:
    int Real ;
    int Image;
public:
Complex(int r=0, int i=0)
:Real(r),Image(i)
{}
~Complex()

  Real=a.Real ;
  Image=a.Image ;
}
Complex& operator=(const Complex& a)
{
    assert(this!=&a);
   Real=a.Real;
  Image=a.Image ;
  return *this;
}
void print()
{
    cout<<Real<<"+"<<Image<<"i"<<endl;
}
friend Complex Add(const Complex& a, const Complex& b);
friend Complex Div(const Complex& a, const Complex& b);
};
Complex Add( const Complex& a, const Complex& b)
{
    return Complex (a.Real +b.Real ,a.Image+b.Image );

}
Complex Div ( const Complex& a , const Complex& b)
{
    assert( b.Real *b.Image !=0);
  return  Complex ( (a.Real *b.Real +a.Image*b.Image)/(b.Real*b.Real  +b.Image*b.Image), (a.Image *b.Real -a.Real *b.Image)/(b.Real*b.Real  +b.Image*b.Image ));
}
int  main ()
{
    Complex a,b,c;
  a.SetComplex ();
  b.SetComplex ();
  c=Div (a,b);
  c.print();
}

~Complex()

  Real=a.Real ;
  Image=a.Image ;
这里是怎么回事?

    a.SetComplex ();
    b.SetComplex ();
这两句又是怎么回事,类Complex没有看到有SetComplex 成员函数.

建议楼主把类的相关概念搞搞清楚.

为什么我发现这么多的错误啊，事实上，我有好几个地方看不懂

不好意思我昨天粘贴的时候搞错了今天从新调试了一下貌似可以运行
