YONKO-SID/C-notes — reverse-engineered prompt

Build me a clean GitHub repo of beginner C programming notes that someone can study from lesson by lesson. I want it to feel like a simple course, starting from what C is and how a basic program works, then moving through variables, data types, operators, input and output, if statements, loops, functions, arrays, pointers, structures, dynamic memory, and file input and output.

Each lesson should be a separate Markdown file with clear explanations, small C code examples, common beginner mistakes, and a short homework project at the end. Please also connect each topic to why it matters for data structures and algorithms, but keep the language easy to understand.

Add a README that explains what the notes are, lists all lessons in order with links, and tells learners to start from lesson 1, compile the examples, and do the homework. Keep the whole thing simple, organized, and useful for someone teaching themselves C.
