error: no match for 'operator='

[gajyamadke]

I am trying to compile sample code but code show errors

   #include<iostream> 
using namespace std; 

class base{
   public:
      virtual void funct(){ 
      cout<<"This is a base class's funct()";
      }
};

class derived1 : public base{
   public:
     void funct(){  
class
     cout<<"This is a derived1 class's funct()";
     }
};
int main()
{
  base *p, b;
  derived1 d1;
  *p = &b;

  p->funct(); //call to base class funct().
  *p=&d1;

  return 0;
}

test.cpp:21:9: error: no match for 'operator=' (operand types are 'base' and 'base*')
*p = &b;

What's the error and how to remove errors ?
