Hi,

for using rand() you can see following example

class base{
public:
int i;
base(int x){int x;}
virtual void func()
{
cout<<"Using base version of func():";
cout<<i<<'\n';
}
};
class derived1: public base{
public:
derived1(int x);base(x) { }
void func()
{
cout<<" Using derived1's version of func():";
cout<<i*i<<'\n';
}
};
class derived2:public base{
derived2(int x):base(x){ }
void func()
{
 cout<<"Using derived2's version of func():";
cout<<i+i<<'\n';
}
};
int main()
{
base *p;
derived1 d_ob1(10);
derived2 d_ob2(10);
int i,j;
for(i=0;i<10;i++)
{
j=rand( );
if((j%2)) p = &d_ob2;
p->func( ); 
}
return 0;
}
