C is a middle-level programming language created by Dennis Ritchie while working at AT&T Bell Labs in the United States in the early 1970s. The goal of its creation was to help with the redesign of the UNIX operating system so that it could run on numerous machines.

The language B was formerly used to improve the UNIX system. Because B is a high-level language, it allows for far faster code generation than assembly language. Despite this, B had flaws, such as a lack of understanding of data kinds and the inability to employ "structures."

These disadvantages prompted Ritchie to create C, a new programming language. He preserved the majority of language B's syntax while adding data-types and making other changes. C was eventually developed between 1971 and 1973, and it included both high-level capabilities and the technical elements needed to create an operating system. As a result, several UNIX components, including the kernel, were eventually rewritten in C.

Features of the C Language

  • C combines the elements of both high-level and low-level languages as a middle-level language. It supports functions of high-level programming languages, such as scripting for software programs, and may be used for low-level programming, such as scripting for drivers and kernels.
  • C is a structured programming language that allows you to break down a big program into smaller programs known as functions. It also permits data to flow freely between these functions.
  • C's properties, such as direct access to machine-level hardware APIs, the presence of C compilers, deterministic resource consumption, and dynamic memory allocation, make it an ideal language for scripting embedded system programs and drivers.
  • Because the C programming language is case-sensitive, lowercase and uppercase letters are interpreted differently.
  • C is a highly portable programming language that is widely used in Windows, UNIX, and Linux operating systems for scripting system applications.
  • C is a general-purpose programming language that may be used to create enterprise software, games, graphics, and mathematics, among other things.
  • The C programming language comes with a large library of built-in functions. It also has a memory allocation system that is dynamic.
  • C quickly constructs algorithms and data structures, allowing for speedier program execution. This has allowed C to be used in programs that require more complex calculations, such as MATLAB and Mathematica.

Applications of C Programming

You can create your own operating system using the C programming language. The kernels of most popular operating systems, such as Microsoft's Windows, Linux, and Apple's OS X, are largely built in C.

Compilers for Programming Languages

Compilers are computer programs that convert high-level languages into machine-readable code. The majority of modern programming language compilers are written in C. Even a portion of the C compiler is written in C. There's a popular adage: “C language is written in C language, and C compiler is used to compile C language”. 

Assemblers

Assemblers are computer programs that convert Assembly Language into Machine Language. GNU Assembler is written in the C programming language.

Different text editors, such as Vim and gedit are written in the C programming language.

Driver Software

Different types of driver software, like network drivers, keyboard drivers, and mouse drivers are written in the C programming language.

Database Software

The world's most popular database software, such as Oracle, PostgreSQL, and MySQL is developed in the C programming language.

Embedded Systems

We employ a variety of embedded systems in our daily lives. Most embedded systems, such as coffee makers, microwaves, and climate control systems are written in C.

Conclusion 

C is a procedure-oriented computer programming language. It may be used to construct lists of instructions for a computer to follow in order to solve a specific problem, or to construct computer software.

C is one of tens of thousands of programming languages in use today. Before we go into the C language in this article, let's take a look at why you should study C (?) among dozens other programming languages currently in use.
