Q71.

What is a significant disadvantage of using linked lists compared to arrays?

Linked lists have a certain memory overhead associated with them

Items are generally not directly accessible through their index

Linked lists have a fixed size

Linked lists cannot store basic data types such as integers

Discuss

Answer: (b).Items are generally not directly accessible through their index Explanation:A significant disadvantage of linked lists is that items are generally not directly accessible through their index, unlike arrays.

Q72.

Why are linked lists a popular method of arranging a list in memory?

They have a fixed size

They can directly access items through their index

They have a lower memory overhead compared to arrays

They can easily add or remove items from different parts of the list

Discuss

Answer: (d).They can easily add or remove items from different parts of the list Explanation:Programs frequently use linked lists in cases where items must frequently be added and removed from different parts of the list.

Q73.

What is the most significant difference between an array and a linked list from a reversing standpoint?

Linked lists have a certain memory overhead associated with them

Items in a linked list are generally not directly accessible through their index

Linked list items are scattered in memory and each item contains a pointer to the next item

Array items are stored sequentially in memory

Discuss

Answer: (c).Linked list items are scattered in memory and each item contains a pointer to the next item Explanation:The most significant difference between an array and a linked list from a reversing standpoint is that linked list items are scattered in memory and each item contains a pointer to the next item and possibly to the previous item (in doubly linked lists).

Q74.

What is the memory overhead associated with linked lists?

Each item contains a pointer to the next item and possibly to the previous item

Items are generally not directly accessible through their index

Linked lists have a fixed size

Linked lists have a certain memory overhead associated with them because of the inclusion of one or two pointers along with every item on the list

Discuss

Answer: (d).Linked lists have a certain memory overhead associated with them because of the inclusion of one or two pointers along with every item on the list Explanation:Linked lists have a certain memory overhead associated with them because of the inclusion of one or two pointers along with every item on the list.

Q75.

What is the main advantage of arrays over linked lists?

They have a lower memory overhead

They can directly access items through their index

They can easily add or remove items from different parts of the list

They can store any type of data

Discuss

Answer: (b).They can directly access items through their index Explanation:Items in arrays can be directly accessed through their index, which is not the case with linked lists.

Q76.

What are singly linked lists?

Data structures containing a payload and a next pointer

Data structures containing an index and a previous pointer

Data structures containing a payload and a previous pointer

Data structures containing an index and a next pointer

Discuss

Answer: (a).Data structures containing a payload and a next pointer Explanation:Singly linked lists consist of a combination of payload and next pointer.

Q77.

What is the purpose of using linked lists in programs?

To access items directly through their index

To arrange a list in memory

To add and remove items from the list

To reduce memory overhead

Discuss

Answer: (c).To add and remove items from the list Explanation:Linked lists are frequently used in programs where items must frequently be added and removed from different parts of the list.

Q78.

What is the disadvantage of using linked lists?

Items are directly accessible through their index

There is a memory overhead associated with them

They are not convenient to use in programs

They can only be used with small data structures

Discuss

Answer: (b).There is a memory overhead associated with them Explanation:Linked lists have a certain memory overhead associated with them because of the inclusion of one or two pointers along with every item on the list.

Q79.

How are items in linked lists arranged in memory?

Sequentially

Randomly

By their index

By their payload

Discuss

Answer: (b).Randomly Explanation:Linked list items are scattered in memory and each item contains a pointer to the next item and possibly to the previous item in doubly linked lists.

Q80.

What is the difference between singly linked lists and doubly linked lists?

Singly linked lists have only a "next" pointer, while doubly linked lists have both a "next" pointer and a "previous" pointer.

Singly linked lists have only a "previous" pointer, while doubly linked lists have both a "next" pointer and a "previous" pointer.

Singly linked lists have only a "next" pointer, while doubly linked lists have only a "previous" pointer.

There is no difference between singly linked lists and doubly linked lists.

Discuss

Answer: (a).Singly linked lists have only a "next" pointer, while doubly linked lists have both a "next" pointer and a "previous" pointer. Explanation:In a singly linked list, each item contains a "next" pointer that points to the next item in the list, while in a doubly linked list, each item contains both a "next" pointer and a "previous" pointer that point to the next and previous items in the list, respectively.
