通常以“是/否”或“真/假”值去决定。 输入/输出 Input/Output 以平行四边形来标示数据输入或输出的过程,即填入数据或显示工作结果的步骤。 注解 Annotation (Comment) 用来补充某步骤的额外信息,可用一个虚线来连接一个半闭合的长方型至想注释的符号中。 已定义流程 Predefined Process 用一个有2条左右垂直
Process Start or End Input / Output Decision Flowchart Symbols You'll notice that the flowchart has different shapes. In this case, there are two shapes: those with rounded ends represent the start and end points of the process and rectangles are used to show the interim steps. These shapes...
A system flowchart is mainly used for physical modeling of the system showing inputs, outputs, and processes. Analysts frequently use them to illustrate the whole system graphically. There are multiple symbols used in a system flowchart. All symbols are unique and represent a different process, in...
Input/output symbol These symbols, usually parallelograms, indicate data inputs and outputs as it enters or is sent out of a process. Connector or flowline symbol These symbols represent a connection between two process symbols, input/output symbols or decision symbols. Usually represented as a li...
Indicates a complicated process or operation that is well-known or defined elsewhere. Internal storage symbol Commonly used to map out software designs, this shape indicates data that is stored within internal memory. Manual input symbol Represents the manual input of data into a field or step in...
If there is no single Start activity, then it will look for any single activity with no input connectors. If it finds such an activity, it will direct tokens to that activity. If there are no activities in the container at all, and the container has a single output connector, tokens wil...

The algorithm and flowchart are two types of tools to explain the process of a program. This page extends the differences between an algorithm and a flowchart,and how to create your own algorithm and
Typically, flowcharts follow a strict rule regarding the type of symbols used for representing each step. These symbols have specific meanings, representing the start, process, connectors, input, output, end, etc. These symbols are represented using different shapes such as a circle, diamond, oval...
In this step-by-step guide, we will walk you through the process of creating a flowchart. Identifying the Process or Task Clearly define the process or task you want to represent. Take the time to thoroughly understand the process, its inputs, outputs, and requirements, for the purposes of...
