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

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!

#include <stdio.h>

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

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

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

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

I'll take C over assembly any day.

I am constantly looking out ways to improve myself. At this stage, I feel like I am capable enough to mentor people.
Fun. Challenging. Interesting
