C Language Programs — Hacktoberfest 2025 🎯🐍

Hi — I’m Dimpesh Panwar 👋 Welcome to the C Language Programs repo for Hacktoberfest 2025! This repo is all about small, well-documented C programs that help beginners learn and contributors practice open-source collaboration.

What I’m looking for

• Follow my GitHub account ✅

• Fork this repo and create a unique Pull Request (PR) — don’t duplicate existing solutions.

• PRs with clear code, comments, and a short description are more likely to be accepted.

• Keep entries beginner-friendly and educational.

Contribution quick-start

• ⭐ Follow my account on GitHub

• 🍴 Fork this repository

• 🔀 Create a new branch: git checkout -b feature/your-short-title

• ✍️ Add your C program inside a descriptive folder (example: sorting/quick_sort.c)

• 📝 Add a short README or comment at the top of your file:

• Program name

• Problem statement

• Input / Output examples

• Complexity (if applicable)

• 🔁 Commit with a meaningful message: git commit -m "Add: bubble sort with explanation"

• 📤 Push and open a PR to main with a clear title and description

• ✅ Ensure your PR is unique — check existing files before adding

• PR checklist (please include)

• Program compiles with gcc (mention the command used)

• File placed in an appropriate folder and named clearly (e.g., math/fibonacci_iterative.c)

• A couple of example inputs & outputs in comments or small README

• No duplicate solution already in repo

• Short description of the approach in the PR body

• Style & conventions

• Use clear variable names and comments.

• Keep functions short and focused.

• Prefer standard I/O (scanf/printf) for examples.

• If your program uses advanced features, briefly explain them at the top.

Ideas to contribute

• Classic algorithms (sorting, searching)

• Number theory (GCD, prime checks)

• Data structures (linked list, stack, queue)

• Small games (tic-tac-toe CLI)

• Problem-solving examples (recursion, DP basics)

• Useful utilities (file I/O examples)
