write a program to find area of curve y=f(x) between x and x=b,integrate between the limits a and b using c

Public derivation Public derivations are much more common than private derivations. In this situation: The private members inherited from the base class are inaccessible
Primarily the term alignment refers the tendency of an address pointer value to be a multiple of some power of two. Thus a pointer with two byte alignment contains a zero in the le
Protected derivation In addition to doing private and public derivations, you may also do a protected derivation. In this situation : The private members inherited
