C is a general-purpose, procedural, portable, high-level programming language that is one of the most popular and influential languages. It was designed to be compiled using a straightforward compiler, to provide low-level access to memory, to provide language constructs that map efficiently to machine instructions, and to require minimal run-time support. Many programming languages owe a considerable debt to C. It has become something of the lingua franca in the programming world.
C is fairly simple to understand. It allows the programmer to organize programs in a clear, easy, logical way. It is a very flexible, practical and compact language combined with an easy to read syntax. Code written in C runs quickly, with easy access to the low level facilities in the computer. Compiler directives make it possible to produce a single version of a program compiled for different architectures.
Here’s our recommended tutorials to learn C. If you’re looking for free C programming books, check here.
learn-c.org is a free interactive C tutorial.
The vision is to teach coding within the browser using short and effective exercises. By running actual code directly from the web browser, students are able to try out coding without installing and executing it locally, which can be hard and redundant for the purpose of learning how to code. This creates a more efficient learning process, because students focus on learning instead of setting up coding environments.
2. C Programming Tutorial by Guru99
This online course teaches you basic to advance level concept of C Programming to make you pro in C language. This is an absolute beginner guide to C Programming.
3. A Tutorial on pointers and arrays in C by Ted Jensen
This document is intended to introduce pointers to beginning programmers in the C programming language.
4. C for Python programmers by Carl Burch
This document is directed at people who have learned programming in Python and who wish to learn about C. C’s “influence on Python is considerable,” in the words of Python’s inventor, Guido van Rossum (“An Introduction to Python for UNIX/C Programmers,” 1993). So learning Python is a good first step toward learning C.

8. Pointers and Memory by Nick Parlante
This document explains how pointers and memory work and how to use them—from the basic concepts through all the major programming techniques. For each topic there is a combination of discussion, sample C code, and drawings.
9. Aalto C by MOOC
This course will teach you the basics of the C programming language. There are no special prerequisites, but some previous programming experience will be helpful.
10. Learn c in Y minutes by Adam Bard
C is the lowest-level language most programmers will ever use, but it more than makes up for it with raw speed. Just be aware of its manual memory management and C will take you as far as you need to go.
