 * The repository provides implementations of various algorithms in one of the most fundamental general purpose languages - [C](https://en.wikipedia.org/wiki/C_(programming_language)).
 * Well documented source code with detailed explanations provide a valuable resource for educators and students alike.
 * Each source code is atomic using standard C library [`libc`](https://en.wikipedia.org/wiki/C_standard_library) and _no external libraries_ are required for their compilation and execution. Thus the fundamentals of the algorithms can be studied in much depth.
-* Source codes are [compiled and tested](https://github.com/TheAlgorithms/C/actions?query=workflow%3A%22Awesome+CI+Workflow%22) for every commit on the latest versions of three major operating systems viz., Windows, MacOS and Ubuntu (Linux) using MSVC 16 2019, AppleClang 11.0 and GNU 7.5.0 respectively.

 * Strict adherence to [C11](https://en.wikipedia.org/wiki/C11_(C_standard_revision)) standard ensures portability of code to embedded systems as well like ESP32, ARM Cortex, etc. with little to no changes.
 * Self-checks within programs ensure correct implementations with confidence.
 * Modular implementations and OpenSource licensing enable the functions to be utilized conveniently in other applications.
