Creational Design Patterns in Modern C++ - Multiple Actors - Part II

The video tutorial explains the process of modifying code to implement an object pool for managing actors. It covers searching for keys in a map, creating and returning actors, and handling cases where keys are absent. The tutorial also details the implementation of functions to acquire and release actors, including error handling and visibility management. Finally, it discusses changes in the main function and demonstrates the proper destruction of actor instances.

What is the first step when searching for a key inside a map?

• Remove the key from the map

• Ignore the key

• Search for the key inside the map

• Add a new key immediately

What happens if the key does not exist in the map?

• The program crashes

• A new key is added along with a vector

• The existing key is updated

• The map is cleared

What is the purpose of the internal create function?

• To print debug messages

• To simplify the implementation of acquiring an actor

• To reset the actor pool

• To delete actors

How is an actor identified within a vector?

• By checking if its visibility is true

• By its name

• By using a lambda expression to find false visibility

• By its position in the vector

What should be done if no actor with false visibility is found?

• Log an error message

• Throw an exception

• Create a new actor

• Return a null pointer

What is the return type of the release actor function?

• int

• string

• void

• boolean

How can an infinite loop be terminated in the main function?

• By using a return statement

• By adding a condition to terminate

• By adding a break statement

• By closing the program
