What is C Programming Language?

C  is a develop for creating system applications that directly interact with the hardware devices such as drivers, kernels etc.. It is machine-independent, structured programming language which is used extensively in various applications.

C was the probable language to write everywhere from operating systems (Windows and many others) to complex programs.

It is said that ‘C’ is a god’s programming language. One can say, C is a base for the programming. C programming is considered as the base for other  programming language .that’s why it is known as mother language.

It is important to have a previous  in computer memory mechanisms because it is an effiecient part when dealing with the C programming language.

It can be defined by the following ways:

  1. Mother language
  2. System programming language
  3. Procedure-oriented programming language
  4. Structured programming language
  5. Mid-level programming language

History of C language

Dennis Richie is known as the founder of C language. It was develop to overcome the problems of previous languages such as B, BCPL etc.’ALGOL’ was used on a large basis in European countries. This was the era of programming languages. Just after three years, in 1970 a new programming language called ‘B’ was introduced by Ken Thompson that contained multiple features of ‘BCPL.’ In 1972, a great computer scientist Dennis Ritchie develop a new programming language called ‘C’ at the Bell Laboratories. It was created from ‘ALGOL’, ‘BCPL’ and ‘B’ programming languages. ‘C’ programming language was developed to be UNIX operating system. .

It inherits many features of previous language such as B and BPCL.. Today ‘C’ runs under a variety of operating systems and hardware platforms. As it started involving various  different new versions of the language were released. At that times it became difficult for the developers to stay up with the new version as the systems were running under the previous versions. You can say that ‘C’ language will remain standard, American National Standards Institute (ANSI) defined a commercial standard for ‘C’ language in 1989. After few years, it was approved by the International Standards Organization (ISO) in 1990. ‘C’ programming language is also called as ‘ANSI C’.

Languages such as C++/Java are developed from ‘C’. These languages are mostly used in different fields of technologies. Thus, ‘C’ forms a platform for many other languages that are currently in use.

where is C used

1.’C’ language is widely used in embedded systems.

  1. It is used for developing system applications.
  2. It is widely used for developing desktop applications.
  3. Most of the applications by Adobe are developed using ‘C’ programming language.
  4. It is used for developing browsers and their extensions. Google’s Chromium is built using ‘C’ programming language.
  5. It is used to develop databases. MySQL is the most popular database software which is built using ‘C’.
  6. It is used in developing an operating system. It is used for developing desktop as well as mobile phone’s operating system.
  7. It is used for compiler production.
  8. It is widely used in IOT applications

why learn C

C  is a low level  language for many programming languages. So, learning ‘C’ as the main language will play an important role while studying other programming languages. It shares the same concepts such as data types, operators, control statements and many more. ‘C’ can be used widely in various applications. It is a simple language and provides faster execution. There are many jobs available for a ‘C’ developer in the current market.

‘C’ is a well structured programming language in which program is divided into various parts Each part can be write in  separately and together it forms a single ‘C’ program. This design to create it simple for testing, maintaining and error  processes.

‘C’ contains 32 keywords, various data types and functions that make programming very useful

Another feature of ‘C’ programming is that it can extend itself. A ‘C’ program contains various functions which are part of a library. We can add our features and functions to the library. We can access and use these functions anytime we want in our program. This feature makes it simple while working with complex programming.

Various sources  are available in the market that can be used for executing programs written in c programming  language.

It is a highly portable language which means programs written in ‘C’ language you can run on another machines. This benefits is important  if you can use or execute the code on another computer.

Features of C language
  1. Simple
  2. Machine Independent or Portable
  3. Mid-level programming language
  4. structured programming language
  5. Rich Library
  6. Memory Management
  7. Fast Speed
  8. Pointers
  9. Recursion
  10. Extensible

C is a structured programming language in the sense that we can break the program into parts using functions. So, it is easy to understand and modify. Functions also provide code reusability. , C programming language to do low-level programming. It is also  used to develop various applications system  such as kernel, driver, etc. It also supports the features of a high-level language. That is why it is known as mid-level language.

  • ‘C’ was developed by Dennis Ritchie in 1972.
  • It is a robust language.
  • It is a low programming level language close to machine language
  • It is widely used in the software development field.
  • It is a procedure and structure oriented language.
  • It has the help us hardware system and various operating system.
  • Many compilers are available for executing programs written in ‘C’.
  • A compiler compiles the source file and generates an object file.
  • A linker links all the object files together and creates one executable file.
  • It is highly portable.
