C language is one of the most popular programming languages!
In recent years, new programming languages such as Swift developed by Apple Inc. of the United States and Hack of Facebook Inc. have appeared one after another. What is the most used programming language for engineers?
Programming Language Popularity Ranking | From Nikkei Crosstech (xTECH)
According to the “Programming Language Popularity Ranking” published in the technical digital media “Nikkei Cross Tech”, C / C ++ is the most common answer to the question “What programming language are you currently using?” The results are coming out. What kind of programming language is this CL used by many engineers?
What is the C language?
C language is one of the historical programming languages developed in 1972. Developed by Dennis.M.Ritchie and Brian.W.Kernighan of AT & T Bell Laboratories, USA.
Currently, it is widely used not only in the United States, where it was developed, but all over the world, and many programming languages have evolved from the CL, such as “C ++” and “C #”. Many people choose CL first when learning to program because they can acquire a wide range of skills from basic programming knowledge to highly practical application skills. Compared to other programming languages such as PHP and Python, the main features of the CL are as follows.
● Highly versatile
Due to its versatility, the CL is used by both amateurs and professional engineers. CL was created to make it easy to port the OS of a computer called UNIX, and it is easy to perform processing closely related to hardware such as memory area management, pointer operation, and bit-by-bit logical operation. Is a feature. However, CL is also used in the field of software development such as embedded software, smartphone applications, and game development, which will be described later. The high degree of freedom to handle anything is one of the reasons why the CL has been used by engineers for a long time.
● Fast programming execution speed
One of the characteristics of the C language is that the programming execution speed is fast. Programs input by humans can only be understood by humans and will not work as they are. Therefore, it is necessary to translate the program into words (machine language) that can be understood by the computer, but if the translation is performed while the program is being executed, the execution speed will be slowed down due to the simultaneous processing.
This method of translating while executing a program is called the “interpreter method” and is used in programming languages such as BASIC and Perl. In contrast to this imprinter method, the method of translating the entire program before executing it to increase the execution speed is called the “compile method”. Since it is necessary to complete and execute the program, there is a drawback that even if there is a problem, it can not be confirmed immediately, but since CL uses this compilation method, the program can be operated at high speed. It is.
● Difficult to learn
Compared to other programming languages, the C language is also characterized by its high level of difficulty in learning. This is because the CL has elements that control the hardware, and knowledge of the parts such as the memory and CPU that make up the computer is essential. Failure to handle unintended behavior or errors can cause your computer or application to malfunction. In addition, even processes that are automatically executed in other languages often require coding in the CL, so appropriate knowledge is required for inputting source code. The more knowledge you have to learn, the more difficult it will be to learn.
However, since C is a programming language that has existed for a long time, there are plenty of introductory textbooks and sites. Although it is a programming language with a high degree of difficulty, it can be said that learning itself is an easy programming language to start. Mastering the C language makes it easier to learn programming languages developed under the influence of the CL, such as Java and Objective-C.
What you can do with C language
As mentioned earlier, the versatile C language is used in various fields.
● OS development
The C language, which excels in developing the core of the system, is also used when designing programs that control hardware, such as operating systems and device drivers. If you raise the OS developed in CL, “Mac OS X” and “Linux kernel” are good examples.
● Embedded software
Embedded software is a program embedded in home appliances and industrial equipment, and is sometimes called an embedded system. Taking the car navigation system as an example, it is necessary to provide specific functions such as “display the current position” and “determine the shortest route to the destination”. In CL, it is possible to develop programs that control these.
Taking advantage of the high processing speed of the C language, there are many cases where even large-scale business software that manages corporate personnel and sales is made in CL or C ++. Also, some familiar software, such as Notepad and Explorer installed in Windows, is written in CL.
Differences from C ++ and C #
What is the difference between C ++ and C #, which are programming languages developed from CL, compared to C language?
● What is C ++?
C ++ is a programming language created in 1983, about 10 years after the development of the C language. It is read as “Sea Plus Plus”, but in Japan, it is sometimes abbreviated as “Sea Plus”. Like the C language, it is a programming language that can control hardware such as the OS and memory and is created by expanding the functions of the C language and incorporating the concept of “object-oriented”. It is compatible with C language, and by using C language and C ++ together, it is possible to create programs with excellent development efficiency. Suitable for hardware control, C ++ is suitable for the development of industrial machines, electronic boards, operating systems, etc. For more information on the object-oriented programming mentioned above and the specific features of C ++, see “What is C ++? What programming language is it?”.
● What is C #?
C # is a programming language developed by Microsoft. It is made in C ++ following the concept of the programming language JAVA. C # is not compatible with C language like C ++, and it can be said that it is a completely different programming language. Although it is not suitable for hardware control like C language and C ++, C # is a programming language suitable for software development such as Windows applications and WEB application development because the developer is Microsoft. The search engine “Bing” and Microsoft’s official website are developed using C #. C ++ and C # have the same point that C is included in the name, but they are very different in terms of features and uses.
As mentioned above, C language, which can be said to be the originator of programming languages, has a simple specification, but because it is simple, it is possible to create a program with a high degree of freedom. If you want to outsource and introduce a C language program, you need to choose a system development company that is strong in C language.
