Developing a C Library Function from Scratch - Technical Interview Series

Given an initial simple description of a library function, ask the right questions, make good assumptions, and develop a working library function in C from scratch. Then proceed through iterations of code, as the stated requirements become progressively more clear, complete, and challenging. Use similar techniques to nail real-world technical interview questions - we'll use an actual coding question from a Microsoft developer interview sequence. Some knowledge of the C programming language at an introductory level is helpful.
