Education is a pass and ticket. With it, you can step into a higher-level environment

Are junior high school students doing nothing to learn programming ？

Education is a pass , One ticket , You have it , You can step into a higher-level environment in advance , So if the sword goes sideways, concentrate on learning programming and give up learning , That doesn't mean you will be affected , But once you need to develop to a higher level , You need to work harder than others , Because you don't have a pass , No tickets .

Many of my classmates like programming , Some people are better off now than me , Some are not as good as me , But those who are better than me are basically no worse than me in the college entrance examination , The college entrance examination school is no worse than me .

I'm learning programming all the way , From the teacher 、 Parental pressure 、 There are also many criticisms , I also survived , But it should be noted that , I can do better , You can also learn programming better （ I C Weak language foundation , Most of the basic things come from BASIC/VB）, But balance is needed .

therefore , You said you study well , First of all, make sure , How good your grades are ？ There is no problem getting admitted to key universities ？ I can only get two copies ？ At least , You can't significantly affect your academic performance by learning programming , Although generally speaking, programming has little impact on academic performance .

The article is relatively long , More words , You can first open the avatar and pay attention to me , Then take your time ,/// Insert a ： At the beginning of this year, I recorded a set of systematic introductory single chip microcomputer tutorial , If you want, just ask me for it. It's free , I can send a private message ~ Click the black font in the lower left corner of my avatar and I can also get it . I've been relatively idle recently , Take me to finish the design , Take students to provincial or above competitions ///

Ask me if I regret learning programming earlier , I regret , The first computer in my family was bought in high school , I used to program on bully in my early years , Later, I went to my cousin's unit to rub the computer .

Ask me if I regret not taking the college entrance examination carefully , I also regret , But I think , I don't spend much time on programming , More often, something else is delayed , such as ： fall in love .

therefore , Don't listen to others , Just edit your program , The premise is that you are really determined to go this way , I need to remind you , People who can finally bring their interests to college graduates , Not much . Be thick skinned , If you are not thick skinned , Then we can only convince parents by keeping their grades .

There are many things that affect academic performance , Learning programming may be a , But it is absolutely of secondary importance , You should make love 、 Take the time to play games to program , I'm sure you'll be great in the end .

Get tickets to key high schools and universities , You win , Make your own program , Let's go .

Now answer a question from a netizen

Why? C The language is designed as a function that needs to be declared before it can be used ？

First , to C It is possible to add a precompile to the language to solve this problem .

Besides, why not precompile ：

First ,C Language appeared very early , At that time, the compiler was also a very complex thing , At that time, the memory of the computer 、 External storage is very small , It is also a troublesome thing for the compiler to do too much , So a prior declaration becomes a norm , Keep it , The purpose is to make the compiler simpler , Although all this is very outdated .

secondly , The cost of precompiling is high , And scripting language 、 The explanation language is different ,C The scale of language projects can be very large , For example, operating system level C Language Engineering , There are tens of thousands of source files , Involving hundreds of thousands of global symbols , The burden of precompiling a project of this size is very high , If the whole project is completely scanned , Traverse all global symbols , Then do the real compilation , It is estimated that many yard farmers will go crazy , The waiting time will be particularly long .

Friends interested in MCU can come to me , I recorded some introductory tutorials about MCU , If you need children's shoes, just ask me for them , Free of charge , Private confidence in me “ Miss Lin ” You can take ～ Click to open my avatar to receive

Again ,C Language is a statically linked language , If a project is designed to compile only , Not linked , For example, some libraries will be designed like this , In some cooperative development projects , Sometimes, only obj file , Then some global symbols may not be included in the existing code , Then pre search will not find some symbols , So what to do ？ If no statement is provided , This code can't be compiled .

Based on the above considerations , therefore C Language is designed like this , For developers , Not friendly , But it's not too bad , Even good in some ways .
