Structural Design Patterns in Modern C++ - Console Facade for Linux

The video tutorial explains the facade pattern and its role in reducing coupling between applications and operating system APIs. It demonstrates how to port an application to Linux using ANSI color codes instead of OS-specific APIs. The tutorial also covers implementing these codes in a console class, compiling, and running the code on different platforms. Finally, it discusses advanced usage of the facade pattern with inheritance to further reduce coupling.

What problem does the facade pattern help solve in the context of using low-level C-based APIs?

• It makes the code more object-oriented.

• It increases the complexity of the code.

• It simplifies the user interface.

• It creates a tight coupling between the application and the operating system.

Why is there no equivalent API for colorizing text in Linux as compared to Windows?

• Linux does not support any form of text colorization.

• Linux has built-in support for text colorization.

• Linux requires the use of third-party libraries for text colorization.

• Linux uses a different programming language.

What is the purpose of using ANSI color codes in the console class?

• To change the font style.

• To make the text bold.

• To increase the text size.

• To colorize text in the console.

What is the role of the 'setcolor' function in the console class?

• To delete the console class.

• To create a new console window.

• To convert enum Color into the corresponding ANSI code.

• To compile the code.

How does the console class ensure platform independence for displaying colored text?

• By using platform-specific APIs.

• By modifying the client code for each platform.

• By using a facade to handle platform-specific details.

• By not supporting colored text.

What is the benefit of creating a base class with child console classes for different operating systems?

• It requires more memory.

• It increases the complexity of the code.

• It reduces the coupling between client code and specific operating systems.

• It makes the code less efficient.

What is the suggested assignment at the end of the lecture?

• To remove all facades from the code.

• To write a new console application.

• To create a base class with child console classes for different operating systems.

• To implement a new operating system.
