My code compiles and runs but does not do what I want.

It is NOT allowed to change main(). I'm trying to build Base(almost like how i typed), Derived classes and type their member functions.

```

#include <vcl.h>

class Base{
public:
void Get_Array();
int max();
void print();
Base();
~Base();
Base(Base&);
int*& getpointer(void);
private:
int *p, size;
};
//----------------------------------------------------------------------------
class Derived:public Base{
public:
int *p, size;
Derived();
~Derived();
Derived(Derived& other);
void swap(Derived& other1, Derived& other2);
void swapsize(Derived& other2);
void Add(Derived& other1,Derived& other2);
Derived& operator-(Derived& other);
Derived& operator+=(Derived& other);
};
//---------------------------------------------------------------------------
#pragma argsused
int main(int argc, char* argv[])
{ Derived A,B;
A.Get_Array(); B.Get_Array();
if(A.size==B.size){
if(A.max()>B.max())
swap(A,B);
else A+=B;
A.print(); }
else{ Derived C(A);
C.size=A.size+B.size;
C.Add(A,B);
C.print(); }
getch();
return 0;
}
