This C Programming Language Tutorial will teach you all you need to know to get started with C, from the fundamentals to the more complex topics of variables, arrays, pointers, strings, loops, etc. This C Programming Tutorial is written for anyone interested in learning or refreshing their understanding of the C programming language, from complete novices to seasoned veterans.

I am taking a mission by myself to learn CyberSecurity, starting with the C Language. So I will share what I will learn. You guys can take it as a roadmap. If you have any questions, email me and I will share what I know.

What is C?

C is a widely used, high-level, procedural programming language that has many applications beyond just the creation of software and apps. In 1972, at Bell Telephone Laboratories, Dennis M. Ritchie created the C programming language. It is a robust and versatile language that was originally created for the purpose of writing software for the UNIX operating system. C is one of the most popular languages used to write computer programs.

The C programming language is widely lauded for its clarity and speed. It’s the finest place to begin learning how to code because it provides a solid groundwork for your future endeavours.

Why Learn C Programming Language

C is often regarded as one of the best programming languages available. Software engineers should definitely take the time to learn it. Since C is considered the “mother” of all contemporary programming languages, mastering it will facilitate your studies of languages like Java, C++, C#, Python, and so on. When compared to other popular programming languages, C language is noticeably quicker. The C code can be compiled on many different computer systems, and it can deal with low-level programming.

Key benefits of the C programming language are as follows:

  • Easy to learn.
  • C is very fast.
  • Versatile Language, which can be used in both applications and technologies.
  • Mid-Level Programming Language.
  • Structured Programming Language.

Features of C Language

C’s capability and power are best demonstrated by the following features:

  • Simplicity and Efficiency: C’s straightforward syntax and organized approach make it a breeze to pick up and use.
  • Fast Speed: In comparison to dynamic languages like Java and Python, C is incredibly fast since it is a static programming language. C’s faster compilation and execution time can be attributed to the fact that it is a compiler-based language.
  • Portable: C allows you to “write it once, run it anywhere” by allowing you to use the same code on several machines. It highlights the machine-independent aspect of the C language.
  • Memory Management: In C, you can manage memory at a lower level with the use of pointers and functions like realloc(), free(), and so on.
  • Pointers: C includes a built-in support for pointers. In order to access or modify the memory, we use pointers. Initiating a pointer as an array, variable, etc., is possible.
  • Structured Language: C’s structural programming features make it easy to break up large chunks of code into smaller, more manageable pieces by employing functions that may be organized into libraries for later use.

Applications of C Language

The operating system development software was written in C. Because C code is as quick as assembly language code, it gained notoriety as a system development language.

The use of C is given below:

  • Operating Systems
  • Language Compilers
  • Assemblers
  • Text Editors
  • Print Spoolers
  • Network Drivers
  • Modern Programs
  • Databases
  • Language Interpreters
  • Utilities

Difference between C and C++?

C is a procedural programming language.C++ is both a procedural and object-oriented programming language.
It does not support Function overloading.It supports function overloading.
Operator overloading is not supported.Operator overloading is supported.
C does not support data hiding which leads to security concerns.Data hiding is supported in C++ by Data Encapsulation.
