Answer 1

To get the output from add, you first need an AddObjects object. Create one in Main() like this:
AddObjects varName = new AddObjects();

Then, call add() through the object, and store the result in an int variable, or print it out:
int result = varName.add();
Console.WriteLine("Result: " + varName.add());

Answer 2

within the main class include
add();
