How to randomly choose one of several strings?
I have this code:
letsdoit(something,'abcd');
letsdoit(something,'asdfasdf');
letsdoit(something,'gagaga');
I want it to be, if possible, just one simple line with the logic like:
(letsdoit(something,'abcd')) OR (letsdoit(something,'asdfasdf')) OR (letsdoit(something,'gagaga'));
so it has 33% chance to choose either of the three. Or:
(letsdoit(something,'abcd')) OR (letsdoit(something,'asdfasdf'))
so it has 50% chance to choose the left or 50% chance for the right thing.
My questions are:
How to randomize between the three and only do one thing.
How to randomize between two things and only do one.
@DavidHeffernan what is the (3) in your example?

It's the number of choices. I take it you read the documentation for Random?

thanks i have solved it like this now
var randomer: integer; randomer := Random(3); if randomer = 0 then begin letsdoit(something,'abcd'); end; if randomer = 1 then begin letsdoit(something,'asdfasdf'); end; if randomer = 2 then begin letsdoit(something,'gagaga'); end;– Fakir Handez

var randomer: integer; randomer := Random(3); if randomer = 0 then begin letsdoit(something,'abcd'); end; if randomer = 1 then begin letsdoit(something,'asdfasdf'); end; if randomer = 2 then begin letsdoit(something,'gagaga'); end;
do not forget to call
Randomize() at the start of your application...– whosrdaddy

function RandomChooseString(const A: array of string): string;
begin
Result := A[Random(Length(A))]
end;
letsdoit(something, RandomChooseString(['aaa', 'bbb', 'ccc']));
i have a question, you used the "letsdoit" but where is the "something"? And I get an error: Error: Incompatible types: 'Integer' and 'String'

Just add this parameter of your
letsdoit. I've shown a method to choose random string. How to use it - your task.– MBo

letsdoit
Do you realize that
RandomChooseString does?– MBo

RandomChooseString
I have to think about it now, I hope i will understand soon

I don't understand all the
(const A: array of string): string; at the top and get some "Incompatible types: 'Integer' and 'String'" error, but it's probably a good answer. i'm just too stupid to understand my mistake– Fakir Handez

(const A: array of string): string;
