# Two Fer `Two-fer` or `2-fer` is short for two for one. One for you and one for me. Given a name, return a string with the message: ```text One for name, one for me. ``` Where "name" is the given name. However, if the name is missing, return the string: ```text One for you, one for me. ``` Here are some examples: |Name |String to return |:-------|:------------------ |Alice |One for Alice, one for me. |Bob |One for Bob, one for me. | |One for you, one for me. |Zaphod |One for Zaphod, one for me. ## 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. ## Source [https://github.com/exercism/problem-specifications/issues/757](https://github.com/exercism/problem-specifications/issues/757) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
