Structural Design Patterns in Modern C++ - Introducing Virtual Proxy

The video tutorial explains the concept of a virtual proxy, which creates objects on demand. It uses a Bitmap class that inherits from an Image class, allowing the client to load and display images. The tutorial highlights the inefficiency of loading large bitmaps when they might not be displayed, and proposes a proxy solution to load images only when needed. The implementation involves creating a base Image class and a Bitmap class that inherits from it, utilizing C-11 features for constructor inheritance. The tutorial concludes with a plan to implement these methods in a subsequent video.

Discuss the implications of loading a bitmap on demand rather than at the time of invoking the load method.

Explain the process of loading a bitmap and when it actually occurs according to the text.

What is the purpose of a virtual proxy in the context of loading bitmaps?

Describe the role of the 'setfilename' function in the Bitmap class.

How does the Bitmap class handle the loading of different types of image files?

What are the constructors required for the Bitmap class and why are they important?

What is the significance of using the C-11 feature of inheriting constructors in the Bitmap class?
