Even though C is often called a simple or concise programming language, it can take years to fully master some of the more advanced features of C programming. Not every topic of C has been covered in this book. The following is a list of those features, with some explanation of each feature and why it was left out of this book:
- Unions: An alternate form of a structure that can take more than one form, depending upon how the union is used. Unions are particularly useful for system-level functions. In my own experience, I have never needed to create a union structure.
- Recursion: A method where a function calls itself repeatedly until some stop condition is met. There are some algorithms that are ideally solved with recursion. To use recursion effectively, both thorough knowledge of those algorithms and an understanding of the performance of the given system are essential.
- Function pointers: This feature was touched upon...
