C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972.
The UNIX operating system, the C compiler, and essentially all UNIX application programs have been written in C. C has now become a widely used professional language for various reasons:

C was initially used for system development work, particularly the programs that make up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language. Some examples of the use of C:
C programming language can be used to design different types of application like designing the system software like OS & compiler.
Designing the application software like database & spreadsheets.
To design the graphics related applications, i.e., PC's and mobile games.
To evaluate the mathematical equations.
C language is one of the powerful languages. Below are some of the features of the C language.
C is the most popular programming language which has many advantages:
It is one of the important characteristics of C. we can split the C program into no. of modules instead of repeating the same logic statements (sequentially). It allows the reusability of modules.
As a middle-level language, C combines both the advantages of low level and high-level languages. (arrays, pointers, etc.).
C can be used to implement any applications such as math’s oriented, graphics, business-oriented applications.
We can compile or execute a C program on any operating system (Unix, dos, windows).
C is a very efficient and powerful programming language, it is best used for data structures and designing system software. C is case sensitive language.
C Language has a list of advantages due to this it is a very much popular language around the world and best suitable for the programmer to learn at the first stage of the programming.
C Language is procedure-oriented language, here user creates procedures or functions to execute their task. Procedure-oriented language is very much easy to learn because it follows an algorithm to execute your statements. To develop a program using procedure-oriented language, you need to draw/prepare an algorithm and then start converting it into a procedure or functions.
C Language provides lots of functions which consist of system generated functions and user-defined functions. C Compiler comes with a list of header files which consist of many general functions which can be used to develop a program, while the programmer can also create a function as per their requirements that are called a user-generated/defined function.
C compiler produces machine code very fast compared to other language compilers. C compiler can compile around 1000 lines of code in a second or two. One more benefit of the C Compiler is that it also optimize the code for faster execution.
C Language syntax is very easy to understand. It uses a keyword like if, else, goto, switch, main, etc. This kind of keyword we all are using in our day to day life to convey meaning or to get some decisions.
C Language setup is around 3-5 MB. So you can carry this language in your Floppy Drive or Pen Drive. It is very easy to install and operate, Again its output is an exe file that can be executed on any computer without any other framework/software.
C Language also has some disadvantages. C Language does not have major disadvantages, but some features are missing in the C Language, obviously, that's why C Language is very much powerful now.
Object-Oriented Programming Features is missing in C Language, You have to develop your program using procedure-oriented language only.
In C Language there is no provision for run-time type checking, for example, I am passing float value while receiving parameter is of integer type then the value will be changed, it will not give any error message.
C does not provide namespace features, so you can't be able to use the same variable name again in one scope. If namespace features are available, then you can able to reuse the same variable name.
C does not provide object-oriented features, so it doesn't have Constructor and Destructor features. Constructor and Destructor are used to construct an object and destroy an object. So in C Language, you have to implement the construction and destruction of the variable manually, using a function or by other means.
