Case Else is an optional statement within the select Case. However, it is a good programming practice always to have a Case Else statement.
Let's find the type of integer with the help of a function.
After that executes the above code, and you will get the output such as:
The number is the least composite number
Let's see some more example of the switch statement, such as
For example, you want to create a custom function (UDF) using the switch statement.
It can be used just like any regular worksheet function, and it will return the grade of the students.
The code for creating the custom formula as follows:
Now, you can use the function GetGrade in the worksheet as shown in the below screenshot, such as:
