Features of C Language

 Today I am going to tell you about the features of C language in this article. Before knowing about the features of C language, you need to know what is C language?

To know in detail about C language, read this article Introduction to C Language? 


C language is the world's oldest programming language, which is taught in schools, colleges and universities to make students aware of computer programming languages.

C language is mainly used to create system software such as operating system, compiler etc.

C language covers the basic features of all other programming languages, therefore, it is said that all other languages ​​are derived from C language.

C Language is a structured programming language which was developed by Dennis Ritchie in 1972 at Bell Laboratories.

We can separate every programming language on the basis of its features because their features make them different from other programming languages.

Let us know about the features of C language, which make it different from other programming languages.

Features of C Language

These are some special features of C language, due to which C language has made its place in the hearts of programmers for the last 50 years.

1. Portability

Programs written in C language are quite portable, meaning programs written in C language can be easily run on different machines or PCs without any changes or changes. The compiler and preprocessor make it possible to run on different PCs.

2. Powerful Programming Language

C Programming Language is very fast and efficient programming language because Data Types, Function and Control Statements have been used in it.

3. Simple Programming Language

C language has commands like English, which makes it very easy for the programmer to write and understand the code.

4. Structured Oriented Language

C Language is Structured Oriented Programming Language. Structured Oriented Programming Language reduces the complexity of the code, which leads to a lot of clarity in the programs.

5. Compiler Based

C Language is Compiler Based Programming Language. This means that programs of C language cannot be executed or run without compiling.

6. Syntax Based Language

C language is Syntax Based Programming Language. Syntax Based Programming Language is the language which follows the rules and regulation very strictly. C Language, C ++ Language, Java Language etc. are Syntax Based Programming Languages.

If a programming language does not strictly follow the Rules and Regulation, then such programming language is loosely called Syntax based programming language like – HTML.

7. Efficient Use of Pointers

Pointer is a variable that points or holds the address of another variable. The performance of programs increases significantly with the use of pointer because direct memory address is accessed in it.

Pointer is used very well in C language.

8. Middle Level Language

C language is a Middle Level Programming Language, which means that low level programming can be done in it and high level programming can also be done, due to which both Application Software and System Software can be made very easily with the help of C Language.

9. Case Sensitive

C language is a case sensitive programming language. This is a special feature of C language. Meaning of Case Sensitive If we write printf like this in one place in C language and PRINTF like this in other place then both mean different in C language.

If the meaning of words written in Lower Case and Upper Case in a programming language is different, then such a programming language is called Case Sensitive Programming Language. C, C++, JAVA, .NET Programming Language is Case Sensitive Programming Language. And such programming languages ​​in which there is no difference between the words written in Lower Case and Upper Case are called Case Insensitive Programming Languages ​​like – HTML, SQL language is case insensitive language.

10. Modularity

In C language, we can divide our code into blocks, which makes it easier to read and write code, this is a technique of designing software, in which a whole program is divided into many functions or blocks.

11. Dynamism

There is also the concept of DMA (Dynamic Memory Allocation) in C language which helps in using and managing the memory very efficiently.

12. Rich Library

C language provides us with pre-built libraries that speed up the creation of programs.

13. Statically Typed Programming Language

C language is a statically typed programming language. Which means that in C language the data type of the variable is checked at the time of compilation of the program, but not at run time. This means whenever the programmer will create a program and use any variable in it, every time the programmer will have to declare the data type of that variable.

14. General Purpose Language

From system programming to photo editing software, the C programming language is used to create various applications. Some common applications where C programming language is used are:

Operating System -: Windows, Linux, Android, OXS, iOS

15. Recursion

In C language we can call Function within Function. This feature allows the code to be reused for each function. 

16. Fast Speed

C programming language is much faster than other programming language because it is a compiler-based language, so it is faster than other programming languages ​​like java, python, which are interpreter based.

17. Extendable

C language can be changed over time. C language has the ability to easily adopt new improvements.

Some interesting facts related to C language

✓ The C programming language was originally created to develop the Unix operating system.

✓ A standard of C language was brought out by ANSI in 1988, after which it was called C88.

✓ Linux OS, MySQL is written in C language.

✓ C language is written in assembly language.

Application of C Language

✓ C language is used to create computer application software like database, spread sheet etc.

✓ C language is used to write Embedded Software.

✓ C language is used to create system software such as Operating System.

✓ To create applications related to graphics such as computer and mobile games.

✓ Unix kernel is completely developed in C language.

✓ C language is used to create network devices and device drivers.

✓ C language is used to make the compiler, the compiler converts the high level code into low level code or machine code.


Friends, today we understand briefly what we learned in this post "Features of C Language" -:

✓ C is a simple and powerful, programming language.

✓ C language is a portable programming language.

✓ C is Structured Oriented, Syntax Based Programming Language.

✓ C is a middle level programming language.
