How to draw a program flowchart

The drawing method of the program flowchart is as follows: Before drawing a flowchart, you need to clarify what a flowchart is. From the literal meaning alone, the flowchart is a flow + chart, which is to present a certain process in an image. A more accurate explanation is that the flowchart is a graphic representation of the flow of information, viewflow or component flow through a system.

What are the types of flowcharts

Flowcharts are generally composed of three structures: sequential structure, selection structure and circular structure. Sequential structure: Just execute the content in order according to the direction of the arrow in the process. Select the structure: select (judge) according to the given conditions, and control the operation process with the selection (judgment) results.

The three basic structures of the flowchart are sequential structure, selection structure and circular structure. Flowchart: The idea of using graphic representation algorithms is an excellent method, because thousands of words are not as good as a diagram. Flowcharts are applied in assembly language and early BASIC language environments.

The shape of each shape in the flow chart means: start shape/end shape, and the "runway circle" shape represents the beginning or end. Processing process, "rectangle". Judging, "rhombus". File: File is generally used to output files or write and modify files.

There are two commonly used forms of flowchart: 1) Up and down flowchart Up and down flowchart is the most common flowchart, which only represents the sequential relationship between the previous step and the next step.The following figure shows the process of purchasing parts of a company.
