I would probably have a few functions on a board with a description, and ask the person to come up with the function mentioned above.

Mere mortals don't know it and spoiled people learn to love the compiler's type safety. More than type safety, spoiled people are used to libraries with overloaded "smart" behavior that "just works" or makes a lot of noise when it doesn't. 2) Some motivation for asking the question. This question is say... 50% about C, 50% about testing. Basically, I think C is scary! No worries though, TDD eats code like this for breakfast :) I wouldn’t stand against this question without:
