An array is a data type containing several elements of the same data type

• True

What is the name given to a composite data type formed by the inclusion of several related items that may be of different data types

• Records

• Arrays

• 2D arrays

• Strings

Which of the following is the correct declaration statement for some data to be used in a program?

• DECLARE <identifier> : <data type>

• <identifier> : <data type>

• DECLARE <data type> : <identifier>

• DECLARE Name : CHAR

What is the name of the algorithm that checks each element of an array in order from the lower bound to the upper bound, until the item is found or the upper bound is reached

• Linear search

• Bubble sort

• Searching an array

• Searching a record

a (a)   sort is a method of sorting where each element of the array is compared with the next element and swapped if the elements are in the wrong order

Why is the loop length for a bubble sort one less than the length of the array?

• The last element in the list does not have an adjacent element to compare it with

• The last element in the list is already sorted

• The length of the array might be dynamic

• None of the options are correct

• READ, OPEN and APPEND

• WRITE, READ and ADD

• OPEN, EOF, CLOSE

Once a file is opened which line of code allows us to write a line to the file?

• WRITEFILE <File identifier>, <Variable>

• READFILE <File identifier>, <Variable>

• APPENDFILE <File identifier>, <Variable>

• WRITEFILE <Variable>, <File identifier>

An abstract data type is a collection of data and a set of operations on that data.

• False
