# Meetup
Calculate the date of meetups.
Typically meetups happen on the same day of the week. In this exercise, you
will take a description of a meetup date, and return the actual meetup date.
Examples of general descriptions are:
- The first Monday of January 2017
- The third Tuesday of January 2017
- The wednesteenth of January 2017
- The last Thursday of January 2017
The descriptors you are expected to parse are:
first, second, third, fourth, fifth, last, monteenth, tuesteenth, wednesteenth,
thursteenth, friteenth, saturteenth, sunteenth
Note that "monteenth", "tuesteenth", etc are all made up words. There was a
meetup whose members realized that there are exactly 7 numbered days in a month
that end in '-teenth'. Therefore, one is guaranteed that each day of the week
(Monday, Tuesday, ...) will have exactly one date that is named with '-teenth'
in every month.
Given examples of a meetup dates, each containing a month, day, year, and
descriptor calculate the date of the actual meetup. For example, if given
"The first Monday of January 2017", the correct meetup date is 2017/1/2.
## Getting Started
Make sure you have read the "Guides" section of the
[C track][c-track] on the Exercism site. This covers
the basic information on setting up the development environment expected
by the exercises.
## Passing the Tests
Get the first test compiling, linking and passing by following the [three
rules of test-driven development][3-tdd-rules].
The included makefile can be used to create and run the tests using the `test`
task.
make test
Create just the functions you need to satisfy any compiler errors and get the
test to fail. Then write just enough code to get the test to pass. Once you've
done that, move onto the next test.
As you progress through the tests, take the time to refactor your
implementation for readability and expressiveness and then go on to the next
test.
Try to use standard C99 facilities in preference to writing your own
low-level algorithms or facilities by hand.
