Developed and introduced a foundational C Tools Suite within the Michaelkelly71/C_Programming repository, delivering three standalone C programs focused on text processing and analysis. The suite included a Caesar cipher encryption tool for lightweight cryptography, a DNA complementary sequence generator supporting basic bioinformatics workflows, and a readability analyzer for evaluating text complexity. Each tool was implemented using core C programming techniques with an emphasis on algorithm implementation and modular design. This initial contribution established a reusable toolkit framework, enabling future enhancements in text manipulation, cryptographic experimentation, and sequence analysis, and marked the beginning of formal tooling in the repository.
