Why don’t you teach arrays in this book?

With an already steep learning curve arrays seemed like a convenient omission to make. Teaching arrays in C is a very easy way to confuse a beginner about pointers, which are a far more important concept to learn. In C, the ways in which arrays and pointers are the same, and yet different, are subtle and numerous. Excluding fixed sized arrays, which have different behaviour altogether, pointers represent a superset of the behaviour of arrays, and so in the context of this book, teaching arrays would have been no more than teaching syntactic sugar.

Those interested in arrays are encouraged to find out more. The book Learn C the Hard Way takes the opposite approach to me, and teaches arrays first, with pointers being described as a variation. For those interested in arrays this might prove useful.
