Freelance IT engineer: Are C language programmers obsolete? Features, demand, future prospects, and merit explanation

Freelance

We will explain the future prospects and demand for programming languages such as the characteristics of the C language, why it is more popular than Java, and its benefits. Although the C language was born in the 20th century, it is still a programming language that is in high demand today.

History of C language

It may be natural that C language is recognized as an old language. The C language was born in 1972 in America. Computer scientist Ken Thompson released C as an improved version of the already existing B language. Since B is followed by C, it is easy to understand that it was named for a very simple reason. The difference between the B language and the improved version of the C language is that data types can now be specified.

The C language is very faithful to the hardware, so it is very useful in middleware development, etc., and is still the main force. In fact, many modern programming languages were developed using the C language. Objective-C, developed by Apple Inc., has its roots in the C language. C++ is also based on the C language.

What are the characteristics of C language?

Some people say that C is outdated because it is a very old language. But why does it continue to be used? Compared to web services, the C language is more difficult for control systems and requires a higher level of knowledge and ability than other programming languages. Depending on the industry and company, there are many cases where OS such as Windows and Linux and application development such as Java are required as skills. Learning is required.

Highly versatile

The strength of the C language is its high versatility. Many things are developed using the C language, so it can be used for any type of development. As a result, you can do anything with it, which is why C is a programming language that has been loved by engineers for a long time and is in high demand.

Fast execution speed

The C language, which uses a compilation method, has fast execution speed. Normally, translation is performed while the program is running, similar to simultaneous interpretation, but this slows down the execution speed. However, in C language, all the code written is translated before the program is executed, and then the PC understands it, so the execution speed is faster.

difficult to learn

Among programming languages, C language is said to be difficult to learn compared to software languages such as the web, depending on the purpose. In particular, failures with structures and pointers are more noticeable. However, if you can learn it, you won’t have any trouble finding a job. You will also mainly be able to use derived languages such as C# and C++. If you can use these and UNIX, you can easily find a job or change jobs by using the free job change service.

C language average annual income

The C language boasts high demand, but how much is it worth in the market? First of all, let’s look at the annual income of salaried workers. You can see well that the annual income of programmers is surprisingly low. It’s not that expensive for both full-time and temporary employees.

But if you become a freelancer, your income will increase significantly. The market price for C language freelancers is around 600,000 to 700,000 per month, which is very high. Of course, this annual income refers to the assumption of 3 years or more of practical experience. If you are inexperienced or have little practical experience, you will have a hard time.

Is there a future for C language programmers?

Since C is an extremely old language, many people are concerned about its future prospects. Will the C language actually survive in the future? In conclusion, it is quite possible. The number of jobs in fields that require the C language is not expected to decrease in the future. It is also used in software development for core systems, machinery, home appliances, robots, game development, etc., making it easy to change jobs.

embedded development

The C language is a language that can give very faithful instructions to the hardware, so it is definitely the main language for embedded development. From now on, the field of hardware development is much stronger than AI, so demand will never disappear. For beginners, the hurdles to studying in a software environment are high, but if you use it, the demand is high. We have a proven track record with a wide range of equipment.

IoT system development

The C language is ideal and useful in the development of IoT systems. In Japan, high growth is expected in the future, especially in the consumer sector where IoT-enabled electronic devices are becoming widespread, the automotive sector where demand for connected cars is expected to grow, and the aerospace sector. C language will be more useful in this field mentioned above than applications. There is value in learning, so it would be a good idea to consult with them first.

Business system development

C language is also in demand for business system development. The C language usage rate is very high in the management of business system development, so there is a huge demand for it in these fields. If you can cope with this, you will have no trouble finding a job. There is also demand for large-scale work sites, and if you aim for this, you will be able to perform a wide variety of tasks, which will be useful.

Demand for C language programmers

Since C language programmers are an old language, there are many middle-aged and older people in their 40s and 50s, but the demand is very high, so if you can do the work on your own, you will not have a hard time. If you are thinking of going independent, you should use a freelance agent. With multiple companies, you will never run out of work. I don’t think the amount of work will decrease in the future, so it is possible to work as a freelancer.

The number of cases is flat

C is said to be a language that has been around for a long time, so there are many middle-aged and elderly engineers as well as young people. There are many projects with high unit prices, but there are not that many projects themselves. However, since the unit price is generally high, you can earn a lot of money. The number of job openings will neither increase nor decrease.

C++

It would be even better if you could additionally learn C++. This is because it is often used together with the C language. It adds value, giving you a significant advantage in your work. It would be a good idea to have at least 2 to 3 years of experience.

What skills are required?

If you want to become a freelancer using the C language, you must acquire the following skills. In recent years, the C language has been in high demand for car and railway development projects, and all sorts of know-how is accumulating. Although my work is concentrated in Tokyo, my value as a programmer is very high. While building a career in urban areas is recommended as a way to obtain projects, there are many remote locations as well.

pointer

Pointers are an absolutely essential skill when using the C language. Even if you look at the design or source code, it is unlikely that there will be no pointers. Many people get frustrated with pointers, but if you don’t understand this, it will be difficult to succeed at a business level. The key is whether you can select hardware such as memory and kernel and be conscious of the purpose of operation. C is compiled and translated from machine language.

OS, Framework, Database

In order to succeed as a programmer who develops complex computer products, you cannot do it with just a programming language, so it is very important to have a complete set of skills, as you will need to know the operating system, frameworks, and even database operations. It becomes. If you acquire specialized skills in your business, you will be able to work smoothly and stay employed for a long time.

other programming skills

It would be even better if you are good at other programming as well. In addition to C#, if you can code in a variety of trending languages such as javascript, ruby, swift, objective-c, go, perl, etc., you can apply each of them, and it will be useful not only for embedded products but also for general application development. Of course, be sure to be good at SQL as well. You can expand your skills and have as many jobs as you like.
