Developed a suite of foundational computational tools and introductory C programs for the Lucho3/BPE2025 repository, focusing on educational use and beginner accessibility. The work centered on implementing basic algorithms and arithmetic operations in C, including utilities for area calculations, number swapping, even and odd checking, and decimal-to-binary conversion. By structuring the codebase with clear, reusable examples and a simple calculator, the project established a practical starting point for learners and new contributors. The approach emphasized clarity and modularity, leveraging C programming fundamentals and pointers to create a maintainable set of exercises that support onboarding and instructional workflows.
