C-Programs

A curated repository of C programs demonstrating core programming concepts, data structures, algorithms, and problem-solving techniques in C.

🖥️ C Programming Repository

📖 Overview

This repository contains all C programs and lab assignments from Semester 1 and Semester 2 of my computer science course.

It provides a structured learning path from basic C programming concepts to advanced data structures and algorithms.

All programs are well-commented, organized by week and topic, and intended as a reference for students and coding enthusiasts.
