    Usage of const in pure virtual function

    Hi All,

    Can anybody clarify me what is the purpose of making pure virtual function as const.

    Like
    virtual double area() const = 0;

    Thanks in advance.

    The same reason as for any other function, the implementation to be shouldn't affect the state of the object.
    Debugging is twice as hard as writing the code in the first place.
    Therefore, if you write the code as cleverly as possible, you are, by
    definition, not smart enough to debug it.
