How many ways can the algorithm be described? What is the difference?

There are many ways to describe the algorithm, such as natural language, structured flow chart, pseudo-code, PAD diagram, etc., among which the most common ones are flow chart and split thinking method.

It is an excellent method to express the idea of the algorithm with graphics in the flow chart, 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.

Operation and operation of data objects: The basic operations that a computer can perform are described in the form of instructions. The set of all instructions that a computer system can execute becomes the instruction system of the computer system. The basic operations and operations of computers can be divided into the following four categories:

1, arithmetic operation: addition, subtraction, multiplication and division.

2. Logical operations: OR, AND, NOT, etc.

3. Relational operations: operations such as greater than, less than, equal to and unequal to.

4. Data transmission: input, output, assignment and other operations.
