#include<iostream>
using namespace std;
class base
{
public:
virtual void fun() { cout <<"base"; } //this is
virtual function
void run() { fun();}
};
class der:public base // base class is
inherited
{
public:
void fun()
{ cout <<"derived"; }
};
int main()
{
der d;
d.run();
return 0;
}
output : derived
but when we remove virtual keyword it gives "base".
why?
i think virtual mechanism is done through only POINTER. Is this
write?
what mechanism is happening
any link about this
