    A friend is not a member of a class but still has access to its private elements.Two reasons that friend functions are useful have to do with operator overloading and the creation of certain types of IO functions.A friend function is defined as a regular ,nonmember function. However,inside the class declaration for which it will be a friend,its prototype is also included,prefaced by the keyword friend.
