An array is a data structure where values are stored adjacently and has something in common. What does each element in an array has something in common?

• name and data type
• name and subscript
• data type and subscript
• data type and superscript

An array has two essential parts: its elements and its subscript. What part directly indicates the length of the array?

• elements
• index
• both element and index
• neither element nor index

In declaring an array, the following are the crucial elements that should be included in the statement. Otherwise, the array is declared incorrectly. Which one is NOT necessary in declaring an array?

• array name
• data type
• array superscript
• array subscript

Using the declaration Dim values( ) As Integer = {1,2,3,4,5} , which of the following is NOT an allowed operation?

• values(4) = 80
• values(2) = values(1) – values(0)
• values(3) = Inputbox(“Enter value for the 4th element”)
• values(5) = 100

Storing values in an array is also known as populating the array. This means giving each element in the array specific values. Check all ways than can populate an array.

• Thru initialization in the declaration statement
• Thru assignment operation
• By accepting user input using input box
• By retrieving values from previous execution

An array subscript or index is a unique identifier for each array element. True or False?

• True
• False

Suppose that you have declared an integer array named numbers, and two of its elements are numbers(1) and numbers(4). It is implied that ______.

• the two elements hold the same value
• the array holds exactly four elements
• there are exactly two elements between those two elements
• the two elements are at the same memory location

You have declared an integer array named values, and two of its elements are values(1) and values(4). It is correct to say that _________.

• values(4) is larger than values(1)
• the array has at least five elements
• the array has been initialized
• the two elements are three bytes apart in the memory
