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 (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.

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

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.
Fun. Challenging. Interesting
