About TheAlgorithms/C

TheAlgorithms/C is an open-source repository (licensed under GPLv3) that provides a comprehensive collection of algorithm implementations in the C programming language. The algorithms span computer science, mathematics, statistics, data science, machine learning, engineering, and more. Each implementation is atomic, using only the standard C library (libc) with no external dependencies, ensuring portability and ease of study. The code adheres to the C11 standard, is well-documented with detailed explanations, and includes self-checks for correctness. The repository is actively tested on macOS and Ubuntu using AppleClang and GNU compilers. It serves as a learning resource for educators and students, offering multiple algorithm strategies for the same problem. Online documentation is generated directly from the source code, including code snippets, execution details, and diagrams.
