Arrays

This document outlines the key concepts of arrays including: - Arrays are a derived data type that store a collection of elements of the same type. - Arrays can be one-dimensional, two-dimensional, or multi-dimensional. Memory is allocated contiguously for an array. - Arrays can be declared and initialized, and passed to functions by reference. - Arrays resemble pointers as they store addresses, but are not the same as pointers. - Operations like sorting, deleting elements, and traversing arrays allows them to be used to solve problems involving matrices, sets, and storing large data sets.
