Behavioral Design Patterns in C++ - Containers - II (List)

The lecture covers the implementation of a linked list as a dynamic data structure. It begins with an introduction to the concept of nodes and pointers, followed by the process of adding nodes to the list. The instructor explains the implementation of the constructor and destructor, highlighting the challenges of accessing elements in a linked list compared to an array. The lecture concludes with a reflection on the implementation and encourages students to think about alternative approaches for accessing elements in data structures.

What is a key characteristic of a one-way linked list?

• Nodes can be accessed in constant time.

• Nodes are stored in contiguous memory locations.

• Nodes contain data and a pointer to the next node only.

• Nodes can point to both previous and next nodes.

Why is adding a node at the end of a one-way linked list considered inefficient?

• It can only be done if the list is empty.

• It requires reversing the list order.

• It requires additional memory allocation.

• It requires traversing the entire list.

What is the purpose of the destructor in the linked list implementation?

• To add new nodes to the list.

• To initialize the size of the list.

• To destroy all nodes and free memory.

• To provide constant time access to elements.

How does the instructor suggest accessing elements in a linked list?

• By using a binary search algorithm.

• By storing elements in an array.

• By providing a function to return the head pointer.

• By overloading the subscript operator.

What is a limitation of linked lists compared to arrays?

• Linked lists can only store integer data types.

• Linked lists do not provide constant time access to elements.

• Linked lists do not allow dynamic resizing.

• Linked lists require more memory than arrays.
