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 proposes using the strategy pattern for more flexibility, allowing different types of mutexes to be used.

Why was a boolean introduced in the class modification?

• To enhance the speed of execution

• To manage memory allocation

• To control the application of locks

• To determine the type of data stored

What is the challenge with applying locks in constant methods?

• They are slower to execute

• They cannot be used in single-threaded applications

• They require a different syntax

• They cannot change the state of the mutex

What is the purpose of making the mutex mutable?

• To increase the speed of execution

• To reduce memory usage

• To allow changes in constant methods

• To simplify the code

What is a potential risk if a call to unlock is forgotten?

• Faster execution

• Data corruption

• Deadlocks

• Increased memory usage

What pattern is suggested to address the complexity of conditional statements?

• Strategy pattern

• Decorator pattern

• Observer pattern

• Singleton pattern

Why is there a need for flexibility in using different types of mutexes?

• To reduce code size

• To accommodate different locking scenarios

• To improve readability

• To increase execution speed

What is the first step in implementing the strategy pattern?

• Removing all mutexes

• Creating a base class for locking and unlocking

• Writing conditional statements

• Optimizing the existing code
