Rust Programming Master Class from Beginner to Expert - Compound Data Types - Tuples, Arrays

This tutorial covers compound data types in Rust, focusing on tuples and arrays. It explains tuples' fixed length and heterogeneity, and demonstrates how to access and destructure them. The tutorial also introduces arrays, highlighting their homogeneous nature and memory allocation. It covers array operations, including initialization, updating elements, and using slices. The tutorial concludes with a discussion on common array functions and their usage.

What is a key characteristic of tuples in Rust?

• They have a fixed length once declared.

• They are mutable by default.

• They can only store values of the same type.

• They can change size after being declared.

How can you access the first element of a tuple in Rust?

• Using the method first()

• Using the index 1

• Using the index 0

• Using the method get(0)

What is the purpose of destructuring a tuple in Rust?

• To change the size of the tuple

• To convert the tuple into a string

• To assign tuple values to individual variables

• To sort the elements of the tuple

How do you access an element in a nested tuple?

• Using a method call

• Using multiple indices

• Using a loop

• Using a single index

What is an empty tuple in Rust?

• A tuple with undefined elements

• A tuple with a null value

• A tuple with no elements

• A tuple with a single element

What must be known at compile time for arrays in Rust?

• The type of elements only

• The size of the array only

• Neither the type nor the size

• Both the type and size of the array

How are arrays stored in Rust?

• In a tree structure

• In non-contiguous memory locations

• In contiguous memory locations

• In a linked list structure

What is a slice in Rust?

• A new array with selected elements

• A method to sort an array

• A reference to a subset of an array

• A copy of an array

What happens if you try to access an out-of-bounds index in an array?

• The compiler throws an error

• The element is set to null

• The program crashes

• The array resizes automatically

What does the 'get' function return if an index is out of bounds?

• The last element of the array

• A default value

• None

• An error message
