Multi-Dimensional Arrays are not just limited to a single dimension, however, they can have a maximum of 60 dimensions. Two-dimensional arrays are the most commonly used ones.

Example

In the following example, a multi-dimensional array is declared with 3 rows and 4 columns.

Private Sub Constant_demo_Click()
   Dim arr(2,3) as Variant	' Which has 3 rows and 4 columns
   arr(0,0) = "Apple" 
   arr(0,1) = "Orange"
   arr(0,2) = "Grapes"           
   arr(0,3) = "pineapple" 
   arr(1,0) = "cucumber"           
   arr(1,1) = "beans"           
   arr(1,2) = "carrot"           
   arr(1,3) = "tomato"           
   arr(2,0) = "potato"             
   arr(2,1) = "sandwitch"            
   arr(2,2) = "coffee"             
   arr(2,3) = "nuts"            
           
   msgbox("Value in Array index 0,1 : " &  arr(0,1))
   msgbox("Value in Array index 2,2 : " &  arr(2,2))
End Sub

When you execute the above function, it produces the following output.

Value stored in Array index : 0 , 1 : Orange
Value stored in Array index : 2 , 2 : coffee
