The project is named `StudentAttendance.csproj` and is located on your computer at `C:\Projects\Task2`

This is your task:
You need to modify the `Program.cs` file to meet the following requirements:
- Ensure that the `FirstName`, `MiddleName`, and `LastName` properties can only be modified within the `Student` class.
- Since some students may not have a middle name, ensure that the `MiddleName` property of the `Student` class allows null values.
- In the `Student` class, create an additional constructor method that accepts only `FirstName` and `LastName`.
- In the `Main` function of the `Program` class, create an instance of the `fStudent` class that has sample `FirstName` of Ben, `MiddleName` of Sam, and `LastName` of Smith.
