What is C language and how to learn?

There are many questions in the mind of many about what is C Language and how to learn C Language. If you want to become a good Software Engineer, then the most important thing for that is coding. Because in technical interviews you can ask their experts to write the theory question as well as the code. In such a situation, if you do not have proper knowledge of programming, then you do not move forward in these interviews.

By the way, questions are often asked in these interviews regarding basic programming languages such as C, C ++. Now the question arises do you know what is this C language? Why is it advised to learn C programming before learning any language? How is it learned? If all these questions arise in your mind too, then today's article is going to be very informative for you on how to learn the C programming language.


Why many people especially students asked us to write about programming languages, as a result of which today I thought why not start it with C language because it is considered the father of all programming languages. If you do not even know about this and you also want to know that despite having other modern programming languages, why should we learn how to make programs in C language, then read this article till the end. Then without taking any further tests of your patience, let's start it and know about the basics of C programming.

What is C Programming Language?

C is a procedural programming language. It was initially developed by Dennis Ritchie between 1969 and 1973. It was mainly developed on the basis of a system programming language, to write programs for the operating system. The main features of the C language are: - Having low-level access to memory, using a simple set of keywords, having a clean style, these features make the C language suitable for system programmings such as operating system or compiler development.

Many later languages have taken many syntax/features from C language, whether in a direct way or indirect way. The syntax of Java, PHP, JavaScript, and other languages are all based on the C language. You can call C++ a superset of C language. There are some programs that compile in C but not in C++.

What are the reasons that C language is used according to a professional language?

  • Let us know about the reasons why C language is used as a professional language.
  • Due to it being a very basic language, it is very easy to learn it.
  • This language is very structured.
  • Very efficient programs can be written using this.
  • It can easily handle very low-level activities.
  • Also, it can be compiled on many computer platforms.

What is the first book based on C Programming?

In 1978, the first book of C Programming, "The C Programming Language", was published. In the first edition of the book, programmers were provided with information about the informal specification of Language. Written by Brian Kernighan and Dennis Ritchie, this book became very popular among C programmers as "K&R".

What are the Features of C Programming Language?

Although there are many features of C Programming Language, here we are going to discuss some important features.

It is a Procedural Language

In procedural languages ​​like C, a list of predefined instructions is followed step by step. In a typical C program, one or more procedures (called functions) are used to perform a task.

If you are new to programming, then you must be thinking that this is the only way all programming languages ​​work. But this is not the case at all because there are other programming paradigms as well. One such commonly used paradigm is Object-oriented programming (OOP) which allows developers to create objects so that they can solve a given task.

C programs are very fast

New languages ​​such as Python and Java offer more features (such as garbage collection, and dynamic typing) than C programming. But in this, the performance is reduced due to additional processing.

C language allows programmers to do direct manipulation of computer hardware. This is not possible in most high-level programming languages. That's why C is considered a better choice for learning programming.

Standard C Programs Are Very Portable

They have a tag line which is "Write once, compile everywhere". Standard C programs are very portable, this means that programs written in one system (for example Windows 7) can be compiled into another system (Mac OS) without any changes.

Using Modularity

If you want, you can store sections of C Code in the form of libraries for future use. This concept is called modularity.

C can do very little work by itself. That is to say that the real power of the C language comes from its stored libraries. There are many standard libraries in C language to solve common problems. Suppose that you have to display something on the screen, then for this you can include in your program "stdio.h" library which allows you to use printf() function.

There is a statically typed language

C is a statically typed language. This means that the type of the variable is checked at compile time and not at run time. The biggest advantage of this is that error detection happens only during the software development cycle. Also statically typed languages ​​are much faster than dynamically typed languages ​​in general if we talk about that.

For many general purposes

Let's say that C is a very old language, but C is used in many applications, whether it is system programming or photo editing software. Let us know about some applications where C programming is used:

Embedded Systems

  • Operating System – Windows, Linux, OSX, Android, iOS
  • Databases – PostgreSQL, Oracle, MySQL, MS SQL Server
  • Other Uses – In-Network drivers, Compilers, Print spoolers

Some interesting facts about the C language

  • 1. C was invented to write an operating system named UNIX.
  • 2. C language is the successor of the B language which was introduced in the early 1970s.
  • 3. This language was formalized in 1988 by the American National Standard Institute (ANSI) J.
  • 4. UNIX OS is totally written in C.
  • 5. In present times, C is the most popular and most used System Programming Language.
  • 6. Mostly all state-of-the-art software is implemented in C itself.
  • 7. Currently the most popular Linux OS and RDBMS MySQL is also written in C.

How to Learn C Language

Why only C Language If you want to learn any language, then first you have to understand that language, for which you can take the help of Online Sources like Websites, Blogs, or Online Courses, whereas in Offline Sources you can read Books or Tutorials Classes. can take help. Below you will find a playlist on YouTube, here you have complete information about how to make a software from C language.

Why is the C language used?

Many times you must have also come to your mind why the C language is still used when there are thousands of languages ​​available in the market. Your thinking is completely justified, but there is some reason behind it, due to which C language is still used.

C was initially used for system development work, mainly they are used to write Operating System Programs. This is because C programming is very efficient as compared to the rest. This is the reason that the language which is more than 40 years old is still used.

Another reason is that Standard C programs are very portable. This source code, which was written in any one operating system, can be compiled or run in another operating system without any changes.

There is also another reason that it is a very good language to learn to program. This is because if you know C programming then you will understand how these programs work, also you can create a mental picture in your mind of how a computer works.

C is used more according to the system development language because it produces such code which runs as fast as the assembly language run. That's why C is used in many places.
