C Programming Tutorials


C programming is a compelling systems programming language that is a general-purpose and procedure-oriented programming language. It is the most widely used programming language as it sets the fundamental paradigm to develop modern operating systems, compilers, and other systems software. It is an excellent programming language to start learning as a beginner programmer.

Why Learn C Programming?

C programming language should be the first programming language for students and professionals to become a great Software Engineer, especially when working in Software Engineering Domain. Here I have listed down some of the critical advantages of learning C Language:

  • It helps to understand how a computer works, i.e., how the data is stored and retrieved in the computer system.
  • It provides the foundation for learning other programming languages such as C++, Java, Python, etc.
  • It can handle all the low-level activities and high-level activities in computer systems and compile in almost all of the development platforms.
  • Here are some of the quotes from people who prefers C as first programming language to learn.

Facts about C Language

  • Language of Choice – C language is still the programming language of choice in OS Development, Compilers, and other Systems software development. Here is the paper studying evolution of C.
  • Structured Programming – To solve a problem, C programming language divides the problem into smaller modules called functions or procedures.
  • Execution Speed – C programs run much faster than any other programming language due to less overhead of libraries and support for other facilities such as garbage collection, dynamic typing.
  • Portable Programming LanguageStandard C programs are much portable and run without any changes in a wide variety of systems.
