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

I am using C and C++ for some years. C is more friendly when compile to assembly.

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

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