How to draw a program flowchart

In software engineeringProgramFlowcharts are essential. How can we draw program flowcharts? Just like writingArticleSimilarly, if you want to write an article, you must first learn to recognize and write the text. Therefore, if you want to draw a flowchart, you must first understand the symbols in the flowchart.

The standard symbols of the program flowchart are shown in:

Sometimes there may be some differences in the various symbols in the flowchart, but there won't be much difference between them. Basically, you can understand what they represent. The most important thing is to reasonably arrange various symbols clearly draw relationships so that others can see at a glance

The specific method of drawing the flowchart:

Similarly, it is similar to writing an article. First, you need to have a clear framework for the whole, draw the entire process, and then break it into several child flowcharts according to its specific functions and structure. Of course, this is the case. the method is to visually check whether the overall structure of the program is correct and reasonable from the flowchart for a relatively large system, and then compile the program based on the flowchart. This can compile a relatively good program and in the design process it is also very convenient to check for functional or process errors WhileIt is enough to draw a whole for those simple systems.
There is no need to draw a flowchart,As a beginner, it is recommended to develop a good habit of drawing a program flowchart before writing a program.
