Is "C Programming language" Still Worth Learning in 2021?

C has been an evergreen language and played a prominent role for most of the system developments that took place in the last few decades. C programming was originally developed by Dennis Ritchie between 1969 and 1973 at Bell Labs and was made for general-purpose, imperative computer programming, that supported structured programming, lexical variable, scope, and recursion etc.

Today, we have lots of programming languages to choose and learn but as a beginner, everybody has a question “Which programming language should I learn first?” and most of the answers that we get on the internet or through suggestions are “C”. In this article, we’ll try to find out if C Programming is still worth learning in 2018. If yes then why?

Where C language is used?

  1. Microsoft’s Windows kernel is developed mostly in C, with some parts of assembly language.
  2. Linux’s kernel is also written in C.
  3. Every driver and program in mac is running on a C-powered kernel.
  4. Ios, android, and windows phone kernel are also written in C.
  5. World’s popular databases, including Oracle, MYSQL, MS SQL server are coded in C. (with C++)
  6. 3D movies are created with applications that are generally written in C.
  7. Embedded systems like an alarm clock, remote and censors controls, etc are most likely programmed in C.
  8. Even my favorite programming language Python also is written in C.

Is It Still Worth Learning C? (Advantages)


As a middle-level language, C combines the features of both high-level and low-level languages. It can be used for low-level programming, such as scripting for drivers and kernels and it also supports functions of high-level programming languages, such as scripting for software applications, etc.


Various features of C including direct access to machine level hardware APIs, the presence of C compilers, deterministic resource use, and dynamic memory allocation make C language an optimum choice for scripting applications and drivers of embedded systems.


C is a highly portable language. It is a hardware-independent language or platform-independent language. It is used for scripting system applications which form a major part of Windows, UNIX, and Linux operating systems.
