Understanding Arrays in Computer Science

What is an array in computer science?

• A collection of variables of different data types

• A collection of variables of the same data type

• A single variable that can hold multiple values

• A function that returns multiple values

Which of the following is a characteristic of a multi-dimensional array?

• It can only store integers

• It is a single row of data

• It can have more than one index

• It is always one-dimensional

What is the primary purpose of sorting algorithms in arrays?

• To add new elements to the array

• To remove elements from the array

• To arrange the elements in a specific order

• To search for an element in the array

Which of the following is a common sorting algorithm used for arrays?

• Binary Search

• Bubble Sort

• Linear Search

• Depth-First Search

What is the time complexity of a binary search algorithm on a sorted array?

In a two-dimensional array, how are elements typically accessed?

• Using a single index

• Using two indices, one for each dimension

• Using a key-value pair

• Using a pointer

Which of the following is true about linear search in arrays?

• It only works on sorted arrays

• It checks each element until the desired element is found

• It requires a binary tree structure

What is the main disadvantage of using a bubble sort algorithm?

• It is difficult to implement

• It requires additional memory

• It can only sort arrays of integers

Which of the following is a benefit of using arrays in programming?

• They can store data of different types

• They allow for efficient random access to elements

• They automatically resize when new elements are added

• They are always sorted

What is the result of accessing an array element with an index that is out of bounds?

• The program will return a default value

• The program will crash or throw an error

• The program will ignore the request

• The program will automatically resize the array
