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

The video tutorial explains how to implement the strategy pattern in CI by creating a dynamic array project. It covers the implementation of common array methods using a vector, and demonstrates how to use the Array class in the main function. The tutorial then explores multithreading with the array, highlighting issues like race conditions and the need for synchronization using mutexes. Finally, it discusses making the array class thread-safe to simplify client usage.

What is the primary purpose of the dynamic array class created in the tutorial?

• To implement a new data structure

• To practice template programming

• To demonstrate the strategy pattern

• To replace the standard vector class

In the context of the tutorial, what is the role of the 'operate' function?

• To perform operations on the array in a separate thread

• To handle user input for the array

• To initialize the array with default values

• To print the elements of the array

What issue arises when two threads access the array object simultaneously?

• The array automatically synchronizes the threads

• Junk values may appear due to race conditions

• The array becomes inaccessible

• The program crashes immediately

Why is a mutex used in the tutorial's multithreading example?

• To allow multiple threads to write simultaneously

• To speed up the execution of threads

• To simplify the code structure

• To prevent data corruption by synchronizing access

What is the main drawback of manually applying locks in the array class?

• It requires clients to handle synchronization

• It increases the complexity of the code

• It makes the array class slower

• It limits the array's functionality

What is the proposed solution to make the array class easier to use in multithreaded applications?

• Implementing a new locking mechanism

• Removing the need for synchronization

• Using a different data structure

• Making the array class automatically thread-safe

What is the effect of adding a delay to the main thread in the tutorial?

• It causes the program to crash

• It allows the operate thread to complete its task

• It speeds up the execution of the main thread

• It prevents the operate thread from running
