Do you want to get a grip on the basic programming concepts from scratch? Do you feel the need to have a better and enhanced understanding of how it all works?  Well, you've come to the right place. This course outlines data types, control flow, functions, input/output, memory, compilation, debugging and other advanced topics in a comprehensive, yet concise manner.

C is where it all begins and where you should also begin to embark on your programming journey. The incredibly efficient and powerful C language forms the basis for many other languages like C++ and Java. It allows you to interact directly with memory and low-level computer operations, thereby enhancing your programming skills and deepening your understanding. This comprehensive and detailed course will introduce you to all the basic and advanced programming concepts of C language. In addition, it also addresses memory, debugging and parallel programming in C.

Sounds awesome? Let's dive in!

Learn C from Scratch

# What is C?
C is a high-level programming language that was developed by Dennis Ritchie at Bell Labs in the early 1970s. It provides fine-grained control over hardware interaction, allowing for highly optimized code. Because of this reason, it has always been popular for systems programming.

It's been the language of choice for writing operating systems. Unix was one of the first operating systems to be rewritten in C (initially, it was written in [Assembly language](https://www.educative.io/answers/what-is-assembly-language)). The core codes of Microsoft Windows, Mac OS X, and GNU/Linux are also written in C, although these operating systems may also use other languages for various components.

C has found other uses as well. It's useful for high performance computing. Compilers and interpreters for several high-level languages like Perl, PHP, Python, R, Matlab, Mathematica, etc., are also written in C.  

# A program in C
