This chapter introduces the topic of data structures—collections of related data items. We discuss
arrays, which are fixed-size collections consisting of data items of the same type, and
vectors, which are collections (also of data items of the same type) that can grow and shrink dynamically at execution time. Both
vector are C++ standard library class templates. To use them, you must include the
<vector> headers, respectively.
After discussing how
arrays are declared, created and initialized, we present examples that demonstrate several common
array manipulations. We show how to search
arrays to find particular elements and sort
arrays to put their data in order.
We build two versions of an instructor ...
