Variable:

A variable is a computer memory location that stores the programmers’ data temporarily.

A data stored in a variable is processed faster than the data stored in the property of a control.

The contents of the variable can be changed during run time.

The user provided data item will be stored in a variable and it will be used in a calculation during run time.

Syntax:

{Dim | Private | Static} variableName As dataType [=initialValue]

Example:

Dim decTime As Decimal

Here, the decTime is declared as a decimal variable and it is automatically initialized by the value 0.

Therefore, the statement user-provided item that will be used in a calculation should be stored in a variable is correct.

Hence, the given statement is “True”.
