Agile development methodology attempts to provide many
opportunities to assess the direction of a project
throughout the development lifecycle.
This is achieved through regular cadences of work, known as
sprints or iterations, at the end of which teams must
present a shippable increment of work. Thus by focusing on
the repetition of abbreviated work cycles as well as the
functional product they yield, agile methodology could be
described as “iterative” and “incremental.”
In waterfall, development teams only have one chance to get
each aspect of a project right. In an agile paradigm, every
aspect of development — requirements, design, etc. — is
continually revisited throughout the lifecycle. When a team
stops and re-evaluates the direction of a project every two
weeks, there’s always time to steer it in another direction.
The results of this “inspect-and-adapt” approach to
development greatly reduce both development costs and time
to market. Because teams can gather requirements at the
same time they’re gathering requirements, the phenomenon
known as “analysis paralysis” can’t really impede a team
from making progress. And because a team’s work cycle is
limited to two weeks, it gives stakeholders recurring
opportunities to calibrate releases for success in the real
world.
In essence, it could be said that the agile development
methodology helps companies build the right product.
Instead of committing to market a piece of software that
hasn’t even been written yet, agile empowers teams to
optimize their release as it’s developed, to be as
competitive as possible in the marketplace. In the end, a
development agile methodology that preserves a product’s
critical market relevance and ensures a team’s work doesn’t
wind up on a shelf, never released, is an attractive option
for stakeholders and developers alike.

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.
