C is a procedural oriented language .
c++ is a object oriented language.
OOps concepts are 1)encapsulation:-Taking data and methods
as an unit is called encapsulation.
2)Abstraction:-Hiding unnecessary data from the user is called
abstraction
3)Inheritence:-producing new classes from the existing classes.
4)Polymorphism:-Ability to exist in more than one form.

Answer / shailesh bahuguna(kec)
basically c does not support the object oriented features
that means we cannot relate the real world entities together
which can be expressed through C++ which is the extention of
c with OOPs concepts
there are many syntactic differences as well in c and c++.
C++ can be viewed as the revolution in the field of object
oriented programming paridigm.

small problems and then make it to be a solution.

Question: Implement a base class Appointment and derived classes Onetime, Daily, Weekly, and Monthly. An appointment has a description (for example, “see the dentist”) and a date and time. Write a virtual function occurs_on(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Then fill a vector of Appointment* with a mixture of appointments. Have the user enter a date and print out all appointments that happen on that date.
