What is C Programing – C Language Basics
In today’s post, what is C language and why should one learn? But we are going to tell you in detail about the oldest programming language in the world. Also where is C programming used? And how to learn C language? You will also find answers to these questions in this article. Today we have different types of assembly language available, by learning which you can become a good programmer and can make many types of software, processor and operating system.
If you are interested in computer programming, choosing and learning one of the programming languages is the most difficult task. For this, you have to see what you want to create and what is the best programming language for that. But if you are new, then it would be wise to start with C language. There are many advantages to learning C Programming Language, the most important advantage is that C language is recognized worldwide.
C language is the root language of many advance computer languages. This means that if you have mastered C programming, you can easily learn many other languages. So let’s first know what is C language? Then we will talk about the remaining aspects of it.

What is C language?
C Language is a general purpose programming language, which is used to create many types of applications. Through C programming, we can develop many types of software from operating systems like Windows or iOS. The machine is also an independent structured programming language. Which means, C language programs can run on different types of computers.
This programming language was developed primarily as a system programming language. C Programming Language is often seen as a middle level language, as it has many features of low level and high level languages. Some examples of this, such as a C language program, can be converted into accembly code, which supports pointer arithmetic.
This feature is in a low level language. The same is machine independent, which is a high level feature. C is also called computer programming language. C programs are portable. Which means, the written source code works in another operating system without any changes.
C is also given the status of compiled language, because once writing a C program you have to run it in C compiler to make it executable so that the computer can understand it. C Language is very popular, simple and flexible. This is the reason, despite being forty years old, it is still used today.
History of C language
If we talk about the history of C Programming Language, it was developed by Dennis Ritchie in 1972 at Bell Laboratories of AT&T (American Telephone & Telegraph). Initially C language was designed to be used in the UNIX operating system. Earlier in 1967, a language called BCPL (Basic Combined Programming Language) was developed mainly for writing system software.
After this, a new language B was created using many features of BCPL. Early versions of the UNIX operating system were created using the B language. C language is a mixed form of both languages B and BCPL. The coding of the program of Unix operating system is done completely in C language.
The C language became more popular when Brian Kernighan and Dennis Ritchie published a book called “The C Programming Language”. Today, C programs are used in many new programming languages. This was the history of the C language, let’s now know where the C language is used.
Where C Programming is used
C programming is used in various fields. Initially, C Language was used for work related to system development. But today due to its characteristics, it is used in different works.
Some examples of where C Programming Language is used are given below:
- Operating System
- Compilers
- Database
- Application Software
- System Software
- Network Driver
Operating System
The C Program is most commonly used in creating operating systems. This operating system (OS) is a type of software that allows the user (user) to run another application on a computer device by communicating with hardware.
Common desktop operating systems include Windows, OS X, and Linux. Each device is operating system in computer, mobile, tablet. Which provides basic functionality to the device.
Compilers
A compiler is a software program that processes instructions written in programming language and converts them into machine language, making it easier for a computer processor to understand them. C Language is used much earlier in the compiler construction.
Database
A systematic collection of data is called a database. Its purpose is to make data management simple and systematic. All the major DBMS software in the world (Oracle, MySQL, MS SQL) is coded in C language itself. Databases are used in all types of systems.
Application Software
The C program is best used in creating Application Software. It is a program or collection of programs commonly used by the end user. The end user is the person who uses them after the software program and hardware device are created. Application software such as database and spreadsheet are created using C language.
System software
System software is a type of computer program, which is designed to run the hardware and application program of the computer. C Programming Language is used in designing operating systems and system software such as compiler.
Network driver
The network driver’s program is also written in the C language itself. The function of these network drivers is to enable the network device to communicate between the computer and the operating system as well as other network computers and network devices.
Apart from this, C language is also used to create Graphics related applications such as computer and mobile games and embedded systems, language interpreters, assemblers. So if you want to make such programs, for that you should know the C language.
Features of C Language
C Language is a widely used language. It provides many features, which are shown below.
1) C language is a simple, popular and extremely powerful language, as it provides many types of data types and functions.
2) It is a machine independent language. Unlike assembly language, the C program can be executed on different machines.
3) C language is used both in low-level programming and high level programming. For this reason, it is known as the mid-level language.
4) C programs are portable, ie they can be run on any compiler.
5) C language is also called structured programming language, because we can break the C program into several parts using functions. Which makes it easy to understand and modify.
6) Number of keywords in C programming language is very less. Its standard version has 32 keywords, so it is very easy to remember them.
7) Due to its flexibility, it is considered very popular for programming embedded systems.
8) C is a fast language. Its compilation and execution time is very fast.
9) Pointers are provided by C language. We can directly interact with memory using pointers. These pointers are used for memory, structures, functions, arrays etc.
10) It supports the feature of dynamic memory allocation. In C Language, we can free the allocated memory at any time by calling the free () function.
Till now we have given you almost all the information about C Programming Language. Hope you know what C language is? So let us now know how to learn that language.
How to learn C language (Learn C Language in Hindi)
If you have decided that you have to learn C language. So the first thing for you is to see where you can start learning it. You do not have to show haste to learn any programming language. First of all, see how I have to learn it, meaning what those resources will be.
