This document discusses arrays in C/C++. Some key points: - Arrays allow storing multiple values of the same type in consecutive memory locations referred by a common name. Elements are accessed using an index in square brackets. - Arrays must be declared with a type, name, and size. They can be initialized with values. Multidimensional arrays represent tables with rows and columns accessed using multiple indices. - Common array operations include passing them to functions by name only, sorting and searching elements (linearly or binary), and traversing through elements in for loops. Arrays provide an efficient way to organize related data.
