What are the characteristics of a program flowchart

I. Characteristics of the flow chart

In our flow chart, each box represents a process, the process line represents the connection between two adjacent processes, which is a directional line, the direction of its direction with the arrow above the identification, to indicate the direction of progress of the process. Obviously, in the process flow chart does not allow the emergence of several processes connected to the first and last circle or loop, of course, each process can be subdivided, you can also draw a more detailed integration diagram, which is completely similar to the algorithmic representation of the flowchart: from top to bottom, gradually refinement.

Note: Closed loops are allowed in the block diagram, but not in the process flowchart.

II. Flowchart drawing

1. program flowchart drawing

Program flowchart is a prescribed graphics, pointing to the line and text description to accurately represent the algorithm of the graphic, with intuitive, graphic features, can clearly show the logical structure of the algorithm. Rules for drawing block diagrams: use standard block diagram symbols; block diagrams are generally drawn in the direction from top to bottom, left to right; in addition to the judgment box, most of the block diagrams have only one point of entry and one point of exit, while the judgment box is the only symbol that has more than one point of exit.
