Flowchart

 A  flowchart is pictorial representation of an  algorithm. Flowchart is  primarily used as an  aid  in formulating and understanding algorithms. The sequencing of instructions and repetition of groups of instructions may be quickly seen by inspecting a flowchart. It uses boxes of different shapes to denote different types of instructions. Actual instructions are written within these boxes using clear and concise statements. Directed solid lines connecting these boxes indicate flow of operations.
