Lecture
This lecture introduces the concept of function pointers in C++, emphasizing their role in event-driven programming for graphical user interfaces (GUIs). It begins with a recap of pointers, explaining how they store memory addresses and how they can be utilized to pass functions as parameters. The instructor details the declaration and initialization of function pointers, providing examples to illustrate their usage. The lecture also covers the importance of matching function prototypes when passing functions as parameters. Furthermore, it discusses the application of function pointers in GTKmm, a library for creating graphical interfaces, demonstrating how to associate functions with GUI events, such as button clicks. By the end of the lecture, students will have a clear understanding of how to effectively use function pointers in their programming, particularly in the context of GUI development with GTKmm.
