C

Join the C Track
C is a small, general-purpose, imperative programming language with a static type system, scopes, and structures. It's typically used as an alternative to assembly programming, such as in operating systems.

About C

#include <stdio.h>

int main(int argc, char* argv[]) {
	printf("Hello, World!\n");
}

C is a general purpose language, used for a wide range of applications, from embedded computers to high-performance computing clusters.

C is commonly found in low level applications as it's a good alternative to harder-to-read assembly languages. It can be compiled to assembly to keep the same level of performance, while increasing readability, and providing a small level of safety with static types!

C was created by Dennis Ritchie at Bell Labs, and used to re-implement the Unix operating system. Now, it's one of the most used programming languages, with many compilers supporting providing support for most available hardware and platforms - there's plenty of resources and support available to help you get started!

Exercism is a great website

What I like about it is that I am able to solve the challenges in a TDD way working in a environment that I am familiar (my own PC not a browser IDE) and the cherry on the top of the cake is that I have access to code reviews.

Relaxed. Encouraging. Supportive.

C is my favorite programming language because of the simplicity it offers and the fact that you can really be in 'total' control of programs written with it. I've programmed in C professionally, at school and for many personal projects.

Loves systems, language, and teaching. Always tries to dive beneath surface layer knowledge. C, C++, Python, Rust, and Scheme. Next will be Idris

I love learning, teaching and using new programming languages. At this moment, writing C#/Typescript most of my working hours.

I've been using C for a long time, mostly doing embedded systems development. I still enjoy programming in C. I value clarity over cleverness.

I am currently a PhD Student in CSE at University of California - San Diego. My interests are in Machine Learning & Embedded Systems. I love programming in C. It was the first language I learnt. I work a lot in systems and hence write a lot of firmware code in C. I've started using Python as well for ML applications. Outside of research I enjoy reading and outdoor activities.

I'm a professional C developer, have substantial experience with Python, and have worked on and off with several other languages. Rust is my favorite new language. I know a little bit about a lot, so send me questions!
Fun. Challenging. Interesting
