In Visual Basic, the Dim statement is used to declare and allocate storage space for one or more variables. The term "Dim" originally stood for "Dimension," as it was used to define the dimensions of an array in early versions of BASIC3. Over time, its usage has expanded to include the declaration of any variable, not just arrays3.
Syntax and Usage
The basic syntax of the Dim statement is as follows:
Dim variableName As DataTypeFor example:
Dim numberOfStudents As IntegerDim message As String = "Hello, World!"In the first example, numberOfStudents is declared as an integer variable. In the second example, message is declared as a string variable and initialized with the value "Hello, World!"12.

The Dim statement can also be used to declare arrays. For example:
Dim scores(10) As IntegerSpecifying Initial Values
