7.1 Introduction

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 array and vector are C++ standard library class templates. To use them, you must include the <array> and <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 ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
