Behavioral Design Patterns in C++ - Dynamic Array - III

The video tutorial discusses modifying a class to apply locks conditionally based on whether it is used in a single-threaded or multi-threaded application. It introduces a boolean to control locking, highlights challenges with the current implementation, and suggests using the strategy pattern for flexibility. The strategy pattern allows for different mutex types and improves code readability and maintainability.

Why is it necessary to modify the class to avoid locks in single-threaded applications?

• To improve performance by avoiding unnecessary locks

• To reduce the size of the class

• To ensure locks are always applied

• To make the class compatible with all programming languages

What role does the boolean play in the modified class?

• It controls the number of threads

• It decides whether to apply locks based on threading

• It changes the class's namespace

• It determines the size of the class

What is a challenge when applying locks in constant member functions?

• Locks cannot be applied in any function

• The mutex state cannot be changed

• Locks are always applied automatically

• The function becomes non-constant

Why is the current implementation hard to read and understand?

• It uses too many classes

• It has conditional statements everywhere

• It lacks any conditional logic

• It is written in an outdated programming language

What is a potential issue with forgetting to unlock in methods?

• It will improve performance

• It can lead to deadlocks

• It will automatically unlock

• It can cause memory leaks

What is the purpose of introducing the strategy pattern?

• To remove all locks

• To eliminate the need for a base class

• To make the code flexible for different mutex types

• To simplify the class structure

What is the first step in implementing the strategy pattern?

• Apply locks to all functions

• Create a new programming language

• Remove all existing classes

• Define a base class for locking and unlocking
