Building Logic with an IF Statement

 Building logic with an IF statement is a fundamental concept in Excel VBA programming. The IF statement allows you to make decisions and execute different sets of instructions based on specified conditions. Here's how you can use an IF statement in Excel VBA:

Sub ExampleIFStatement() 
' Declare variables 
Dim num As Integer 
' Assign a value to the variable 
num = 10
' Use an IF statement to check a condition 
If num > 5 Then 
' If the condition is true, execute this block of code 
MsgBox "The number is greater than 5." 
Else 
' If the condition is false, execute this block of code 
MsgBox "The number is not greater than 5." 
End If 
End Sub

In this example:

We declare a variable named "num" of type Integer.

We assign a value of 10 to the variable "num".

We use an IF statement to check if the value of "num" is greater than 5.

If the condition (num > 5) is true, the message "The number is greater than 5." is displayed in a message box.

If the condition is false, the message "The number is not greater than 5." is displayed.

You can also use additional logical operators such as "<" (less than), "<=" (less than or equal to), ">" (greater than), ">=" (greater than or equal to), and "<>" (not equal to) to create more complex conditions in your IF statements. Additionally, you can use multiple IF statements together with ELSEIF and ELSE clauses to handle multiple conditions.

Sub ExampleMultipleConditions() 
' Declare variables
    Dim num As Integer 
' Assign a value to the variable 
num = 10 
' Use multiple IF statements with ELSEIF and ELSE clauses 
If num > 10 Then 
MsgBox "The number is greater than 10." 
ElseIf num = 10 Then 
MsgBox "The number is equal to 10." 
Else 
MsgBox "The number is less than 10." 
End If 
End Sub

In this example, the program checks if the value of "num" is greater than 10, equal to 10, or less than 10, and displays the appropriate message accordingly.
