When a Derived Class object is assigned to Base class, the
base class' contents in the derived object are copied to
the base class leaving behind the derived class specific
contents. This is referred as Object Slicing. That is, the
base class object can access only the base class members.
This also implies the separation of base class members from
derived class members has happened.
class base
{
public:
int i, j;
};
class derived : public base
{
public:
int k;
};
int main()
{
base b;
derived d;
b=d;
return 0;
}
here b contains i and j where as d contains i, j& k. On
assignment only i and j of the d get copied into i and j of
b. k does not get copied. On the effect object d got sliced.
