Default Value

How do I add a default value, non editable, to a field while the field itself is open for input…

or

how do I add a default hidden constant to a field that is inserted before the user input

or

is it possible to populate a field with the input from two other fields

Ex.
Field 1 User input ‘1234’
Field 2 User input ‘5678’
Field 3 = ‘12345678’
