Quiz on Arrays and Linked Lists

What is an array primarily used for?

• Storing different types of data

• Storing data with variable size

• Storing data in a non-sequential manner

• Storing similar data

How are elements in an array accessed?

• By their size

• By their memory address

• By their value

• By their index or subscript

What is a disadvantage of using arrays?

• They allow dynamic memory allocation

• They have a fixed size

• They are easy to insert and delete elements

• They occupy more memory than linked lists

What is a linked list composed of?

• Nodes

• Arrays

• Elements

• Indexes

What does each node in a linked list contain?

• Only data

• Only a link to the next node

• Data and a link to the next node

• Data and a link to the previous node

What is an advantage of linked lists?

• Fixed size

• Dynamic data structure

• Faster access to elements

• Less memory usage

What is a disadvantage of linked lists?

• They have faster search times

• They are easy to insert and delete elements

• They require more memory for storing links

• They are static in size

How is an element deleted from a linked list?

• By shifting elements

• By changing the link of the previous node

• By removing the node from memory

• By setting the node to null

What is the main characteristic of an array?

• Elements can be of different types

• Elements are linked to each other

• Elements are stored in contiguous memory locations

• Elements are stored in non-contiguous memory

Which operation is more efficient in linked lists compared to arrays?

• Memory allocation

• Insertion and deletion

• Searching for elements

• Accessing elements
