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!

A tremendous learning opportunity to explore the depth of your own knowledge

Exercism is fantastic in learning new languages but that is not the extent of it. If you are a "more experienced" programmer you may have encountered impostor syndrome: the idea you don't really know what you think you know. Exercism lets you solve problems and put them in the space of open feedback which is a tremendous learning opportunity to explore the depth of your own knowledge. Even if you have been programming in a language for awhile it is worth checking into Exercism to see where you stand with current implementation practices.

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.

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.

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

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!
Fun. Challenging. Interesting
