This document discusses flowcharting symbols and structures used to represent algorithms and program flow. It describes common flowcharting symbols from standards organizations like ANSI and ISO, which are used to represent elements like inputs, outputs, processes, decisions, and data flow. It also outlines the three basic control structures for modeling program logic: sequence, selection, and iteration.
