Chapter 11 Using Arrays to Manage Numeric and String Data 277

Working with Array Elements

To refer to an element of an array, you use the array name and an array index enclosed

in parentheses. The index must be an integer or an expression that results in an integer.

For example, the index could be a number such as 5, an integer variable such as num, or

an expression such as num-1. (The counter variable of a For... Next loop is often used .)

For example, the following statement assigns the value “Leslie” to the element with an

index of 5 in the Employees array example in the previous section:

Employees(5) = "Leslie"

This statement produces the following result in our Employees array:

9

8

7

6

5

4

3

2

1

0

Employees

Lesile

Similarly, the following statement assigns the number 4 to row 0, column 2 (the top of the

third inning) in the Scoreboard array example in the previous section:

Scoreboard(0, 2) = 4

This statement produces the following result in our Scoreboard array:

0

0 1 2

4

3 4 5 6 7 8

1

Rows

Columns

Scoreboard

You can use these indexing techniques to assign or retrieve any array element.
