 * Well documented source code with detailed explanations provide a valuable resource for educators and students alike.
 * Each source code is atomic using [STL classes](https://en.wikipedia.org/wiki/Standard_Template_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-Plus-Plus/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 19 2022, AppleClang 14.0.0, and GNU 11.3.0 respectively. 
-* Strict adherence to [C++12](https://en.wikipedia.org/wiki/C%2B%2B12) standard ensures portability of code to embedded systems as well like [ESP32](https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-guides/cplusplus.html#c-language-standard), [ARM Cortex](https://developer.arm.com/documentation/101458/2404/Standards-support/Supported-C-C---standards-in-Arm-C-C---Compiler), 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.
