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.

I love Rust and C and use them at my day job in automotive. I work with Embedded software but I'm also reasonably familiar with systems programming as well

The language which got me interested in programming. Most of my open source contributions have been in C.

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.

C (or rather C++) are the languages which pay my rent. I've been using, loving and hating them since about 1999, when I got involved with the KDE (https://www.kde.org) project.
Fun. Challenging. Interesting
