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.

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.

Loves systems, language, and teaching. Always tries to dive beneath surface layer knowledge. C, C++, Python, Rust, and Scheme. Next will be Idris

I am currently a PhD Student in CSE at University of California - San Diego. My interests are in Machine Learning & Embedded Systems. I love programming in C. It was the first language I learnt. I work a lot in systems and hence write a lot of firmware code in C. I've started using Python as well for ML applications. Outside of research I enjoy reading and outdoor activities.

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

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
