Answer / rasagna

resuability is the excellent concept in cpp. we can reuse
the functions many times.but in c we have not that type of
facility. classes gives redability and data security
(because of access specifier)to program. oop(object
oriented program) gives class as high in cpp.because of
inheritance,polymorphism,data independence.encapsulation.


At last what i want to say is

c + extra reatures = c++.
c + class = c++
