dkv204p/c-programming ? reverse-engineered prompt

Build me a simple C learning repository that helps beginners understand the language through clear examples and practice programs. I want it organized into sections for basic tutorials, functions, file handling, structures, enums, and some data structures and algorithms in C. Each section should have small, easy to read programs with comments that explain what is happening so someone can learn by opening the files and running them.

Please make it feel like a helpful study guide, not just random code samples. Add a short README that explains what each folder is for and how to use the examples. Keep everything beginner friendly and practical, with clean code and a few hands on exercises people can try themselves. If you need to check current best practices for C examples or docs, look them up online.
