🚀 CodeAlpha C++ Internship Projects

This repository contains three complete C++ console applications developed as part of the CodeAlpha C++ Internship Program.

Each project addresses a specific task assigned by CodeAlpha and demonstrates strong understanding of Object-Oriented Programming (OOP), file handling, program structure, and user interaction using modern C++.
