Structural Design Patterns in Modern C++ - Protection Proxy Example

The video tutorial explains how to set up an employee repository using pointers and paths, implement file operations with error handling, and enhance method logic. It demonstrates creating repository instances, managing employee access, and introduces future enhancements for access restrictions.

What is the purpose of using a pointer for Employee in the repository?

• To simplify the code structure

• To manage employee access to the repository

• To store employee data permanently

• To enable dynamic memory allocation

Why is it necessary to enable the C-17 standard in Visual Studio for this implementation?

• To use advanced debugging features

• To access the latest C++ libraries

• To ensure compatibility with the file system API

• To improve code execution speed

What happens if the path does not exist when trying to create a file?

• The file is created in a default location

• An exception is thrown

• A warning message is displayed

• The operation is ignored

How does the compiler locate the 'exists' function in the file system namespace?

• By checking the function signature

• Using a predefined list of functions

• Through argument-dependent lookup

• By using a global search

What change is made to the condition for viewing a file?

• The condition is changed to check if the file exists

• The condition is updated to check file size

• The condition is removed entirely

• The condition is modified to check file permissions

What is the purpose of wrapping the repository access in a try-catch block?

• To log all operations performed

• To handle potential exceptions during file operations

• To ensure only one employee accesses the repository at a time

• To improve code readability

What is the role of the proxy mentioned in the final section?

• To provide a backup of the repository

• To simplify the code structure

• To restrict access to the repository based on employee roles

• To enhance the performance of file operations
