How to draw the process, is there any rule?

1. The traditional flow chart is shown in the following figure:

2. Detailed description of the flow chart:

(1) defines three variables, which are I (for loop counting), M (for saving larger values) and A (for input values).

(2) Assign a value to the loop variable I.

(3) Input the first number a, assign the value of a to m, and initialize the value of m..

(4) entering a loop, in which it is first judged whether the loop conditions are compound, if the conditions are met, a new value A is input, the value of A is compared with the previous value of M, and a larger value is assigned to M, and the loop variable I+1; If the condition is not met, the variable m with relatively large value is output to obtain the result.

Simply put, it is the comparison of two numbers, and the large value is saved and finally output.

Flowchart: It is an excellent method to express the idea of algorithm with graphics, because a thousand words are not worth a picture. Flowchart has been applied in assembly language and early BASIC language environment. There is also a related PAD diagram, which is very suitable for PASCAL or C language.

Flowchart is an effective method to reveal and master the motion state of closed system. As a diagnostic tool, it can assist decision-making, let managers know clearly where the problem lies, and then determine alternative action plans.

The basic structure of the flow chart includes: sequence structure, conditional structure (also called selection structure), cyclic structure and branching structure.
