Class
------------------------------------
The programming language to use here is not stated, so standard output is not clear. A solution using text boxes for input and output can be given in Delphi:
unit Unit2;
interface
uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls;
type TForm2 = class(TForm)
Edit1: TEdit;
Edit2: TEdit;
procedure FormCreate(Sender: TObject);
private { Private declarations }
public { Public declarations }
end;
var Form2: TForm2;
implementation
{$R *.dfm}
procedure TForm2.FormCreate(Sender: TObject);
var i: integer;
txtline: string;
begin
i := StrToInt(edit1.text);
txtline := IntToStr(i) + ', ' + IntToStr(2 * i) + ', ' + IntToStr(i * i); edit2.text := txtline;
end;
end.
Answer:
Probably would use LAN
Explanation:
Schools use LAN to connect students to their networks, so it would make sense for them to use LAN for offices. They could use ethernet if all their PCs are hard wired in, though.
