练习写一个运算符重载,出错,请教各位.

 
  class   CA  
  {  
  private:  
   
  int   m_n1;  
  int   m_n2;  
  char   pch[256];  
  public:  
  CA();  
  CA(int   n1,int   n2);  
   
  ~CA();  
  CA   operator+(int)   const;  
  };  
   
  CA::CA(int   n1,int   n2)  
  {  
  m_n1=n1;  
  m_n2=n2;  
  };  
   
   
  CA   CA::operator+(int   n)   const  
  {  
  CA   caTmp=*this;  
  caTmp.m_n1=caTmp.m_n1+n;  
  caTmp.m_n2=caTmp.m_n2+n;  
   
  return   caTmp;  
  }  
   
  test_operator_in_class   error   LNK2019:   unresolved   external   symbol   "public:   __thiscall   CA::~CA(void)"   (??1CA@@QAE@XZ)   referenced   in   function   "public:   class   CA   __thiscall   CA::operator+(int)const   "   (??HCA@@QBE?AV0@H@Z)
