During March 2025, Troev Play developed a suite of foundational educational utilities for the Lucho3/BPE2025 repository, focusing on beginner-level C programming. He implemented basic computational tools such as area calculations for various shapes, number swapping, even and odd number checking, and a decimal-to-binary converter. The work emphasized clear, reusable code using C and fundamental concepts like pointers and arithmetic operations, providing a practical introduction for new learners. By contributing introductory C samples and a simple calculator, Troev established a structured, accessible codebase that supports onboarding and hands-on learning, though the scope remained limited to essential features without bug fixes.
