The classical introductory exercise. Just say "Hello, World!".
"Hello, World!" is the traditional first program for beginning programming in a new language or environment.
The objectives are simple:
If everything goes well, you will be ready to fetch your first real exercise.
To compile and run the tests, just run the following in your exercise directory:
$ nim c -r hello_world_test.nim
Note that, when trying to submit an exercise, make sure the solution is in the
You can find your Exercism workspace by running
exercism debug and looking for the line that starts with
For more detailed information about running tests, code style and linting, please see the help page.
This is an exercise to introduce users to using Exercism http://en.wikipedia.org/wiki/%22Hello,_world!%22_program
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
import unittest import helloworld suite "Hello World": test "no name": check helloworld() == "Hello, World!" test "sample name": check helloworld("Alice") == "Hello, Alice!" test "other sample name": check helloworld("Bob") == "Hello, Bob!"
proc helloworld*(name = "World"): string = "Hello, " & name & "!"
A huge amount can be learnt from reading other people’s code. This is why we wanted to give exercism users the option of making their solutions public.
Here are some questions to help you reflect on this solution and learn the most from it.
