This document provides code examples for arrays in C++. It contains 3 code snippets with explanations: 1. A program that takes input from the user to populate an array and then prints the contents of the array. 2. A program that takes input to populate an array, defines a function to calculate the sum of array elements, and calls the function to print the sum. 3. The beginning of a program to find the union of elements in two arrays, by checking if each element of the first array matches an element of the second array.
