Tic-Tac-Toe with C++ Course Syllabus

This project-based course guides you through building a complete Tic-Tac-Toe game in C++ from scratch, culminating in an unbeatable AI opponent using the Minimax algorithm. You'll gain hands-on experience with core C++ programming concepts while implementing game logic, input validation, win/draw detection, and modular code organization. With approximately 2.5 hours of focused content, this concise course is designed for beginners seeking practical experience in C++ development, problem-solving, and basic AI. Each module includes coding exercises that reinforce software engineering best practices, including testing and code structure.
