The C programming language is one of the most widely used programming languages and has huge importance in Computer Science. Because of its fundamental structure, it is being preferred by Google and Algorithm Development. Initially, it was developed for working on operating systems (i.e. UNIX OS) for minicomputers, but lately, it gained much importance in every field. C language is a general-purpose, portable, and easy-to-use programming language that makes it important for everyone.

IncludeHelp has several C programming tutorials from beginners to advanced algorithmic problems with examples and explanations to provide better learning resources. In addition to learning C tutorials, we have provided articles for the best Job preparation, including Interview Question sets.

What is C Language?

C is a procedural computer programming language that has been used throughout the world for over four decades. Bell Labs have a significant contribution to the development of Electrical Engineering and Computer Science, and C language is one of those contributions. Dennis Ritchie, between 1972 and 1973, initially developed C. During the 1980s, C gradually started gaining popularity around the globe, and it has become one of the most widely used programming languages. Since 1989, C has been standardized by the ANSI (ANSI C) and by the ISO (International Organization for Standardization).

C facilitates structured programming and allows us to implement recursion and lexical variable scope as a procedural language. 

C has a definitive memory management system by providing three different ways to allocate memory for objects:

• Static memory allocation
• Automatic memory allocation
• Dynamic memory allocation

Moreover, C as a Programming language exhibits other characteristics listed below:

• It consists of a large number of bitwise, logical, and arithmetic operators: +, +=, ++, &, ||, etc.
• C has a fixed number of keywords (i.e. small set), so it also provides us a free hand to use multiple terms throughout the code.
• It also includes a full set of control flow primitives i.e. if/else as conditional and, for, do-while, while as loop primitives.
• C has a definitive feature i.e. Functions:
  1. Functions in C permit run-time polymorphism.
  2. Values returned by a function can be ignored, when not needed.
  3. Functions can be defined with different scopes

Applications of C Language

C is not an outdated language and many world's leading companies are using C programming for their computational development. Most of the software is based on C, and it laid the foundation of other programming languages. Many algorithms are implemented in C and therefore, it also opens wide opportunities in research. Moreover, because of its fundamental features and its ability to be a foundation of computer science, It is still the most preferred programming language for programmers and back-end developers.

Following are the key applications of C as a Programming Language:

• Software Development
• Operating Systems
• Graphical User Interface Development
• Gaming and Animation
• Hardware Manipulation
• Embedded Systems
• Robotics
• Competitive Programming
• Job at Google!!
