C is a computer programming language designed to communicate with a machine generally a computer. Programming languages are used to create programs that control the behaviour of a machine.

The C Language is developed for creating system applications that directly interact with the hardware devices such as drivers, kernel etc. C programming is considered as the base language for other programming languages, that is why it is also known as mother language.

There are many reasons why 'C is so popular'? Some of the reasons are listed below:

  1. C is reliable, simple and easy to use.
  2. Learning C++, Java, C#, or any other advance languages is difficult to understand without knowing the concept of C language.
  3. Major parts of operating systems (Windows, UNIX, Linux) is still written in C.

C Language Uses

  • C is widely used for system programming in implementing operating systems and embedded system applications, because C code is portable, can be used for most purposes, system-specific code can be used to access specific hardware addresses.
  • C can also be used for website programming using CGI as a "gateway" for information between the Web application, and the browser. C is often chosen over interpreted languages because of its speed, stability, and universal availability.
  • C enables programmers to create efficient implementations of algorithms and data structures, useful for computationally intensive programs. For example, the GNU Multiple Precision Arithmetic Library, the GNU Scientific Library, Mathematica, and MATLAB are completely or partially written in C.
  • C has also been widely used to implement end-user software applications. However, such applications can also be written in newer, higher-level languages.

C - Related languages

C has both directly and indirectly influenced many later languages such as C#, D, Go, Java, JavaScript, Perl, PHP, Python, and UNIX's C shell. The most, all of the languages mentioned combine the statement and expression syntax of C.

When object-oriented languages became popular, C++ and Objective-C were two different extensions of C that provided object-oriented capabilities. Both languages were originally implemented as source-to-source compilers, the source code was translated into C, and then compiled with a C compiler.

Editor for C

To start working with C Language we need an editor (IDE - Integrated Development Environment) in which we can write and run code, there are lots of code editors available, my recommendation is: Turbo C++ (Borland) and VS Code (Microsoft). In this series of tutorial, I have used VS Code editor to write programs as well as I will explain the difference between writting code in VSCode and Turbo C++.
