What can be described by the flow chart is that

When drawing a flowchart, the commonly used graphic symbols are rectangle, diamond, parallelogram, circle or ellipse, arrow, rectangle with arrow, etc.

1, rectangle

Represents a process or operation, which is used to describe calculation, comparison or other operations in an algorithm.

2. Diamond shape

Represents a decision point, which is used to represent the conditional judgment in the algorithm. The diamond usually contains a judgment statement, which determines which subsequent operation to flow to according to the conditional result.

3. Parallelogram

Represents an input or output operation, which is used to represent the input and output of data.

4, round or oval

Represents the beginning and end of the algorithm. The circle indicates the beginning and the ellipse indicates the end.

5. Arrow

Indicates the direction of the process, which is used to connect various graphic elements and indicate the execution order of operations.

6. Rectangle with arrow

Represents a loop operation, which is used to represent the loop structure in the algorithm, such as for loop and while loop.
