## Flowchart It is a diagrammatic representation of the steps of an algorithm. It is a pictorial representation that can be used as a substitute for an algorithm, as a textual description of an algorithm may not be understood easily. Flowcharts are classified into two (2) categories: - **Program flowcharts** - illustrate the logical steps in a software program or programming task to understand a process, workflow, or algorithm. They contain the steps of solving a problem unit for a specific result. - **System flowcharts** - show how parts of a system work together by displaying the data flow and how decisions can affect the events surrounding it. Boxes of different shapes are used to represent various types of operations. Lines then connect these boxes with arrows representing the direction or flow to which one should proceed to know the next step. Here are the standard symbols used in program flowcharts. | Symbol | Name | Description | | :-------------------------------- | :-------------------- | :--------------------------------------------------------------------------------------------------------------------------------- | | A circle with a line | Terminal | Shows the start and end of a set of computer-related processes | | A rectangle with a line | Input/Output | Shows any input/output operation | | A rectangle | Computer Processing | Shows any processing performed by a computer system | | A rectangle with a line | Predefined Processing | Indicates any process not specially defined in the flowchart | | A rectangle with no lines | Comment | Used for writing any explanatory statement required to clarify something | | A line with an arrowhead | Flow line | Used for connecting the symbols | | A rectangle with curved lines | Document Input/Output | Used when input comes from a document, and output goes to a document | | A diamond | Decision | Shows any point in the process wherein a decision must be made to determine further action | | A circle with a line | On-page Connector | Connects parts of a flowchart continued on the same page | | A downward facing triangle | Off-page Connector | Connects parts of a flowchart continued to separate pages | **Table 1**.
