IF THEN ELSE

Another basic example of IF THEN ELSE.

procedure TForm1.btnCheckClick(Sender: TObject);
var age : Integer;
begin
age := StrToInt(edtAge.Text);
if (age>=18) then
ShowMessage('Congratulations! You are old enough to vote!')
else
ShowMessage('Sorry, you are not old enough to vote yet...');
end;
