Drawn using certain special-purpose symbols. How to determine the flow of data through a network and identify process logic? What is a flowchart? Is a graphical representation of an algorithm or of a portion an algorithm. Drawn using certain special-purpose symbols. Rectangles Diamonds Ovals Small Circles These symbols are connected by arrows called flowlines.

Symbols Rectangle Also called action symbol Indicates any type of action including a calculation or an input/output operation Add 10 to Grade

Flowlines (Arrows) Indicate the order in which the actions are to be performed.

Ovals Contains the words Start/Begin Stop/End Start

Small Circles Also called connector symbols A

Diamond Also called the decision symbol Indicates a decision is to be made NO Grade < = 59 Yes

Input/Output Represents data that is available for input or resulting from processing.

Example of a Flowchart Start No Yes Print Pass Stop Enter Grade Print Failed Print Pass Stop
