Behavioral Design Patterns in C++ - Organization - I

The lecture introduces the iterator design pattern, demonstrating its use in accessing employee objects within an organization without exposing the internal storage structure. The instructor outlines the implementation of an organization class using an array to store employees and discusses the importance of the iterator pattern in providing access to these objects. The lecture concludes with a promise to explore multiple access methods in future sessions.

What is the main purpose of using the iterator design pattern in the context of the organization class?

• To add more attributes to the employee class

• To allow client code to access employee objects without knowing their storage details

• To fix the size of the employee array

• To directly expose the internal array of employees

What is the primary data structure used to store employees in the organization class?

• Linked List

• HashMap

• Tree

• Array

What is one of the functions added to the organization class?

• Update employee

• Remove employee

• Add employee

• Search employee

Why is it not advisable to directly expose the internal array of employees?

• It would make the code more complex

• It would expose the internal implementation details

• It would require more memory

• It would slow down the program

What will be discussed in the upcoming lectures according to the conclusion?

• How to increase the size of the employee array

• Different ways to expose the internal array

• Multiple ways to provide access to employees without exposing internal implementation

• How to add more attributes to the employee class
