How to learn a programming language systematically| Dark horse programmer

One 、 Start with knowing programming languages ：

There are many languages , Including Chinese 、 English 、 French 、 Korean, etc , Although the form of output is different , But it can achieve the same purpose . Again , We can adopt 「 Language 」 To control the computer , Let computers do things for us , Such a language is called programming language .

eg. An example of a fully automatic washing machine

Have you ever used an automatic washing machine ？ Do you know how it works ？

​

The working steps of the automatic washing machine are as follows ：

“ Feed water with detergent — wash — dehydration （ water ）— inlet — Rinse — dehydration （ water ）—（ dry ）— Whistle to signal  ” The program work of , In good order , Wash clothes automatically , Is it convenient ！ How does it do it ？

original , Manufacturers in the washing machine control chip , A series of instruction codes are input in advance , Different algorithm programs are preset , Make the washing machine work automatically according to people's choice , This process is also called “ Programming ”.

Two 、 Understand the basic working principle of computer

To be exact, learning how to program is the only way to truly enter the computer world , And the study of the principle of computer runs through the whole computer science . Now let's introduce some of these parts ：

Circuit principle ： This is the bottom hardware content , Some schools teach physics to computers 、 Analog circuit 、 Courses related to digital circuits , Learn through these courses , Will have a thorough understanding of the physical basis of computers .

How it's made up ： It mainly introduces what constitutes a computer , Each component such as CPU、 Memory 、 How hard drives interact , And some basic knowledge of computer system ; Reference books -->《 Deep understanding of computer systems 》.

Operating system principle ： This section mainly introduces the operating system （ for example windows） What are you doing , How does it interact with the hardware , What is the interaction with the software we usually use ？ These questions will be learned in this course .

Network principle ： This is a course that will lead you into the world of computer network , You can learn how the network works , How data is transmitted through the Internet , What is the router doing ？ It's often said IP What's the address ？

mathematics （ theory ） principle ： Here are the relevant parts of computer science theory , The computer we usually use will be abstracted into a computing model in a mathematical world , Then we study its related properties .

Compiler principle ： The course of compiling principle is a comprehensive course of the core computer theory of the whole undergraduate course , It will tell us how to put a complex high-level programming language （ Such as C Language ） Transform into something that the machine can understand and execute 01 strand .

The above tutorial can be conducted according to From the front to the back Step by step , The course content is divided into sections and knowledge points , Convenient for everyone to learn , And there are also small practice cases after each stage , It is convenient for everyone to learn advanced .

▼ Hot issues ： How to calculate “ Master ” A programming language ？

Master a programming language , Is to know everything about it . for instance ：

• The background of it
• What problems it solves
• What is its design idea
• What are its advantages and disadvantages
• What are its classic projects
• Under what circumstances should it be used
• What is its current state of development
• ......

In our actual work, most people stay at the level of being able to use , Able to complete basic tasks , This is not to be “ Master ” Of .

For example, it is like learning mathematics ,“ Be able to solve problems with formulas ” and “ Can deduce this formula ”, This is fundamentally different .
