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

Exercism is a great website where I was able to have some very interesting challenges.

Relaxed. Encouraging. Supportive.

I started Programming with C and loved it. Later, I coded in C++ and learned Python. But the affection to C is still in my heart.

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

I've been writing code for 35+ years and I continue to learn things when I read another person's code

I love C because despite the prevalence of high-level languages, C continues to empower the world. I mostly code in C and also use it for open source projects.

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.
Fun. Challenging. Interesting
