Passing Optional and Named Parameter

By utilizing optional parameters in C#, we can enhance the versatility of our methods. Assigning default values within the method parameter list allows us to make certain parameters optional, allowing for more flexible method calls.

Step 1: In Person.cs, add statements to define the method, as shown in the following code:
