# Grade School
|
||
|
|
|
||
|
|
Write a small archiving program that stores students' names along with the grade that they are in.
|
||
|
|
|
||
|
|
In the end, you should be able to:
|
||
|
|
|
||
|
|
- Add a student's name to the roster for a grade
|
||
|
|
- "Add Jim to grade 2."
|
||
|
|
- "OK."
|
||
|
|
- Get a list of all students enrolled in a grade
|
||
|
|
- "Which students are in grade 2?"
|
||
|
|
- "We've only got Jim just now."
|
||
|
|
- Get a sorted list of all students in all grades. Grades should sort
|
||
|
|
as 1, 2, 3, etc., and students within a grade should be sorted
|
||
|
|
alphabetically by name.
|
||
|
|
- "Who all is enrolled in school right now?"
|
||
|
|
- "Grade 1: Anna, Barb, and Charlie. Grade 2: Alex, Peter, and Zoe.
|
||
|
|
Grade 3…"
|
||
|
|
|
||
|
|
Note that all our students only have one name. (It's a small town, what
|
||
|
|
do you want?)
|
||
|
|
|
||
|
|
|
||
|
|
## For bonus points
|
||
|
|
|
||
|
|
Did you get the tests passing and the code clean? If you want to, these
|
||
|
|
are some additional things you could try:
|
||
|
|
|
||
|
|
- If you're working in a language with mutable data structures and your
|
||
|
|
implementation allows outside code to mutate the school's internal DB
|
||
|
|
directly, see if you can prevent this. Feel free to introduce additional
|
||
|
|
tests.
|
||
|
|
|
||
|
|
Then please share your thoughts in a comment on the submission. Did this
|
||
|
|
experiment make the code better? Worse? Did you learn anything from it?
|
||
|
|
|
||
|
|
To run the tests simply run the command `go test` in the exercise directory.
|
||
|
|
|
||
|
|
If the test suite contains benchmarks, you can run these with the `-bench`
|
||
|
|
flag:
|
||
|
|
|
||
|
|
go test -bench .
|
||
|
|
|
||
|
|

## Submitting Incomplete Problems
|
||
|
|
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
