Most often, we will need to understand this relationship when we pass arrays to functions. So, understanding the interchangeability of arrays and pointers will be essential to making any function that manipulates arrays more flexible and expressive.

Having read two previous chapters, Chapter 11, Working with Arrays, and Chapter 13, Using Pointers, is essential to understanding the concepts presented here. Please ...
