### 124 C topics, one page each — look it up, copy the example, run it

I built this handbook myself. Every topic gets its own page with the same five boxes: **definition → syntax → use case → example program → expected output**. Nothing to read front to back — you jump to the page you need and get back to your code.

📕 **[The Well Structured C.pdf](https://onehack.st/uploads/short-url/7JfObYxOMMc22n5ktTx43TzdCdX.pdf)** (8.0 MB) — 175 pages, 15 sections, 124 topics, from your first program to function pointers and file handling

🗺 **[The C Well Structured Learning Path.pdf](https://onehack.st/uploads/short-url/aBCYEq9uiesw07GQCU22oEOCrra.pdf)** (305 KB) — the same 124 topics as a plain checklist, so you always know where you are

_Note: this book does not cover DSA._

> **What's inside — all 15 sections**
>
> Introduction · Variables & Data Types · Operators · Flow Control · Functions · Loops · Arrays · Pointers · Scope & Memory · Dynamic Memory Allocation · Strings · Multidimensional Arrays · Structures & Unions · Function Pointers & Files · Recursion
> 
> Practice problems sit inside the sections, not at the end: prime factorization, palindrome check, matrix multiplication, GCD and LCM, pattern printing, and “predict the output” operator puzzles with the evaluation written out line by line.
