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'm a professional C developer, have substantial experience with Python, and have worked on and off with several other languages. Rust is my favorite new language. I know a little bit about a lot, so send me questions!

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've been using C for a long time, mostly doing embedded systems development. I still enjoy programming in C. I value clarity over cleverness.

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