Proficient in C language and what can C do?

C/C language is widely used, so what can learning C/C do?

1. Laboratory development

I dare not say that C is the best language in the world, but C is basically a big language among engineering students.

It is said that C is both process-oriented and object-oriented, with excellent running speed and good large-scale project development ability, which can dominate university laboratories.

2. Back-end development

There are only a few mainstream back-end development languages, led by Java and C, followed by Python and Go.

3. Game development

After mastering the basic grammar of C, developing games is still a good choice. At present, the industrial 3D game engine is still written in C or C.

Although you can't complete a huge online game on your own, it's a very good choice to start with something simple, write some small games, and then go deeper and deeper, step by step, and finally join a large game development team. Corresponding jobs are mainly game development engineers and game engine architecture engineers.

4. Client development

After all, C is a very mature language, so there are actually many other development positions to choose from besides back-end development. Naturally, it is the client development.

I believe that most students who study C have used C to write desktop software. At that time, it was estimated that MFC was still used, and a relatively simple interface could be written by tapping on the code book. So if you don't want to be a backend, you can find a client development job by C. Being a client also needs a solid programming foundation and computer theory foundation, and may also be familiar with Windows/C compilation and linking mechanism, QT client development technology system, Windows message mechanism and other technologies.

So, if you study C and don't care about the inexplicable job discrimination chain in the industry, it is also very good to find a client development job. It's just that compared with back-end development, you may need to re-examine the role of the client.

5. Multimedia development

At present, multimedia technology has also penetrated into people's daily life, and audio and video have become a very important means for people to obtain information. Audio and video are compressed and packaged according to certain rules during transmission. Video coding technology has developed for more than 3 years from the initial H.261 to today's H.265, and all the codes are realized by C or C.

The latest HEVC coding standard is realized by C code. If you are interested in this, you can go to ITU (International Telecommunication Union) official website to download the source code after learning C grammar. Corresponding jobs are image algorithm engineer, video coding R&D engineer, audio and video transcoding engineer, etc.

6. Embedded development

The above job choices are all in the direction of software, and C/C has a very big employment direction, that is, to be embedded. Embedded itself may be a little bit hardware-oriented, but now everything is hard and soft.

The development of embedded system also involves network programming and concurrent programming. The popular explanation may be that the embedded code runs on other small systems, rather than the traditional computer. This direction requires not only programming ability, but also basic circuit theory literacy.

Generally, companies that recruit embedded development posts are mostly Internet companies that mainly focus on hardware products, such as Xiaomi and Huawei. Many companies are doing things related to the Internet of Things. After all, this is a hot spot. Of course, there will be other business directions, such as chips and robots.

7. artificial intelligence

artificial intelligence, machine learning and other directions are also indispensable to c or c language.

It should be emphasized that although C language can be used in a wide range of directions, it is far from enough to master C grammar. The above-mentioned application fields are based on C language. To enter these fields, it is necessary to further systematically learn the knowledge in related fields and get in touch with the contents of real enterprise projects.
