Answer / lakshmi.t
If a class B is derived from A, we can access the data and
member function of A.So in order to access a class data or
function from another class we have to derive the class.
but this can be done by declaring a class as 'friend' and
can access the another class functions and data.

Answer / mital
A friend function is used in object-oriented programming to
allow access to private or protected data in a class from
outside the class. Normally a function which is not a
member of a class cannot access such information; neither
can an external class. Occasionally such access will be
advantageous for the programmer; under these circumstances,
the function or external class can be declared as a friend
of the class using the friend keyword. The function or
external class will then have access to all information –
public, private, or protected – within the class.

Answer / nitish
If you are not the actual member of the class and want the
access over the functions involved in the class, then it can
be done through friend function.
An easy access to the data is provided through friend functions.
