About C

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 providing support for most available hardware and platforms - there are plenty of resources and support available to help you get started!

Key Features of C

Cross-platform

C is portable and can run on almost any platform and chipset.

General purpose

Can be used for a wide variety of workloads from IoT to game engines.

Fast

Consistently rated as one of the highest performing languages for energy and time.

Stable

The C standard values stability and backwards compatibility, C programs can run for decades.

Powerful

Allows both lower and higher level functionality, making it very powerful.

Widely used

Consistently one of the most popular languages for everything from operating systems to firmware
