Zufallsvariable

[Hans33]

was ist dann falsch?
Ich kann kein denkfehler erkennen!

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Button1: TButton;
    Label2: TLabel;
    procedure Button1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  public
    z :integer;
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}


procedure TForm1.FormCreate(Sender: TObject);
begin
randomize;
z := random(50)+1;
end;
procedure TForm1.Button1Click(Sender: TObject);
var r : real;
begin
  r := StrTofloat(edit1.Text);

       if r < z then Label2.Caption := 'Zu niedrig'
  else if r > z then Label2.Caption := 'Zu hoch'
  else if r = z then Label2.Caption := 'Erraten';
end;
end.
