This method is most widely used as its more flexible, you can set the value in the placeholders which will display your text according, for example I want to Write a code where in I want whenever the user login to their account the system should display

Welcome First name Last name

Console.WriteLine("Enter your first name");

string FirstName: Console.ReadLine();
