Arrays in pseudocode

What does the following describe: group of elements having the same data type which are stored in a linear arrangement under a single variable name.

• 1D Array

• 2D Array

• Index

• Element

What does the following describe: a collection of data elements arranged in a grid-like structure with rows and columns. This uses a pair of indices

• 1D Array

• 2D Array

• Index

• Element

What does the following describe: The number used to access values in an array.

• 1D Array

• 2D Array

• Index

• Element

What does the following describe: A data value in an array

• 1D Array

• 2D Array

• Index

• Element

Which one of the following is the correct way to declare a 2D array in pseudocode

• Declare ClassList : ARRAY: [1:10, 1:2] OF STRING

• Declare ClassList : ARRAY: [1:10, 1:2]

• Declare ClassList : ARRAY: [1:10] OF STRING

• ClassList : ARRAY: [1:10, 1:2] OF STRING

What type of loop do we use to output the contents of a 1D array, where the number of elements remain known and fixed

• FOR LOOP

• NESTED FOR LOOP

• WHILE LOOP

• REPEAT LOOP

What type of loop do we use to output the contents of a 2D array, where the number of elements remain known and fixed

• FOR LOOP

• NESTED FOR LOOP

• WHILE LOOP

• REPEAT LOOP

How many elements are there in the following declaration of an array: Declare ClassList : ARRAY: [1:10, 1:2] OF STRING

• 20

• 10

• 2

• Unknown

Why is a standard for loop not suitable to access each element of a 2D array

• An array has a pair of indices, a single for loop will only provide a single counter

• It will skip elements

• It will output only the entire row and ignore data in each column

• All the answers are correct

What does an array is zero indexed mean?

• The index starts at 0

• The index starts at 1

• All of the elements contain the value 0

• None of the options are correct
