Event-Driven Programming
Mock Exam
Course Introduction
Event-Driven Programming introduces the principles and practices of building software systems that respond dynamically to external and internal events. Students learn to design and implement programs that use event listeners, handlers, and callback functions to manage user interactions, sensor inputs, and real-time data streams. The course covers event loops, event propagation, and asynchronous programming models commonly used in graphical user interfaces, web applications, and embedded systems. Practical assignments emphasize modular code organization, responsiveness, and reliability in handling concurrent events across different programming environments.
