Structured C programming practice covering core concepts, logic building, and problem solving

💻 C Programming Fundamentals

This repository contains my C programming practice work completed during the first semester of my B.Tech in Artificial Intelligence & Data Science program.

The project is organized topic-wise and focuses on building a strong foundation in procedural programming, problem solving, and logical thinking using the C language. Each folder represents a specific concept area practiced through multiple programs.
