Object_

How Object-slicing implemented in c++ ?

For Object slicing refer this [URL="http://www.linuxtopia.org/online_books/programming_books/thinking_in_c++/Chapter15_017.html"]link[/URL]

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.

[CODE]class base
{
public:
int i, j;
};
class derived : public base
{
public:
int k;
};
int main()
{
base b;
derived d;
b=d;
return 0;
}[/CODE]
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.
