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

The reviews are incredibly helpful because they help me see things that I missed, learn about new ways and sometimes interesting discussions that can add a fun twist to maybe a simple problem.

Relaxed. Encouraging. Supportive.

C was the first programming language I learnt and it still is one of my favorites. I wrote C professionally for Linux Kernel!

I am very interested in the theory of OS. Most OS kernels were written in C, for example, the Linux kernel. I would like to teach beginners programming in C, because C uses a large number of low-level concepts that every programmer should know.

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 love to spread my knowledge. I'm using C and C++ from past 4 years. I love them because of their simplicity and friendliness.

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