In this blog, you'll get to know a vast description of C Language.

What is C Language?

C programming is a general-purpose, procedural, imperative computer programming language developed in 1972 by Dennis M. Ritchie at the Bell Telephone Laboratories to develop the UNIX operating system. C is the most widely used computer language. It keeps fluctuating at the number one scale of popularity along with the Java programming language, which is also equally popular and most widely used among modern software programmers.


Prerequisites for learning C Language

You need to know nothing much before starting learning C. Basic knowledge about logic building skills, and mathematics are enough to start learning it.

Understanding C

There are a fixed structure and syntax for writing a program in any language, and writing it in any other form will give a compilation error. It means that we have a fixed structure for writing a C program as well.

Structure of C

Header - #include <stdio.h>

Main - int main ()


Variable Declaration - int a = 10;

Body - print ( "%d", a);

Return - return 0;


What Is C Used For?

The c programming language is a very simple language generally used by programmers worldwide. Originally, this language was applied for system development work, in precise, the programs that make up the operating system. The advantage of the C programming language is that it generates code that works almost as fast as code written in assembly language. The uses of C programming can be summarized as follows:

  • The c programming language is originally practiced for system programming. The portability, performance, capacity to reach particular hardware addresses, and low runtime command on system addresses make it a good choice for executing operating systems and embedded system applications.
  • It is universally accepted by compilers. Libraries and interpreters of other languages are often performed in C programming.
  • There are various uses of c programming in electrical engineering also. It can use signal processing algorithms to know the features of microprocessors, microcontrollers, and other integrated circuit projects.
  • C programming is sometimes utilized as an intermediary language for implementations of different languages because of portability and comfort reasons. Examples of compilers that use C language in this process are Gambit, BitC, the Glasgow Haskell Compiler, Vala, and Squeak.
  • There are many uses of c programming in mechanical engineering. Different CAM and CAD software are to be controlled by engineers. Almost every project is created with CAD and CAM software has a vital role in the production processes.
  • C programming is extensively utilized to implement end-user applications.

Advantages of C Language

  1. Being a middle-level language, C connects the features of both low-level and high-level languages. C language can be utilized for low-level programmings, such as scripting for kernels and drivers. It also helps the use of high-level programming languages, such as scripting for the application of software, etc.
  2. The c programming language is a structured language that provides a complicated program to be separated into more simplistic programs described as functions. It also enables data-free movement over these functions.
  3. C programming languages have different features, that includes access to machine-level hardware APIs, the behavior of compilers of C, and dynamic memory allocation that make the C language an excellent option for scripting applications and drivers of installed systems.
  4. This programming is case-sensitive, which means uppercase and lowercase letters are used separately.
  5. Uses of c programming are for scripting system applications, which form a significant part of Windows, Linux, UNIX operating systems.
  6. C language is a general-purpose language and can efficiently work on project applications, graphics, games, and applications needing calculations.
  7. It has a powerful library that provides several built-in functions. It also gives dynamic memory allocation.

Who should learn C?

Whether you are new to programming, you should learn it because of the following reasons:

  • It is around 50 years old and is still very popular.
  • It builds a strong foundation of programming. Because it has its compiler, the program written in it runs on the C compiler only. So, it will not only teach you programming or coding, but it will also let you understand how a program runs on the computer.
  • It will make you a hardcore programmer as it has lesser libraries. So, you will end up writing your code.

Career growth

Some companies work on embedded programming, system programming compiler designing, etc., looking for good C professionals and giving a good career growth. This technology will not die and will always provide a good career opportunity.


C is considered as the base of other programming languages. This technology doesn’t seem to have an expiry date. Its specialty to provide interaction with the hardware makes it unique. Its portability and efficiency make it a good choice for complex data manipulation and the development of embedded systems and operating systems kernels. Many other programming languages are also in demand, but they can’t beat it, which is still preferred when performance becomes the priority.
