[Scenario]

I need a way to generate random strings consisting of numeric characters only. I searched and went through over 10 pages but couldn't find anything. Can anyone assist me?

[JaTochNietDan]

Couldn't you just use the random function a few times? If I read correctly all you want is a string of numbers right? If you don't care about the length you could just use something like random(500000); and if you do care about the length, just use random(9) a few times and then put them all in a string.

[Scenario]

Wouldn't that be inefficient?

[=WoR=Varth]

pawn Code:

format(string,sizeof(string),"%d",random(9999));
format(string,sizeof(string),"%d%d%d%d",random(9),random(9),random(9),random(9));

[Scenario]

Unless someone else responds with a better solution I can just use the code "varthshenon" provided. Thanks!

[=WoR=Varth]

Another.

pawn Code:

valstr(string,random(9999));

IDK which one is faster.

I need the string to end up being 6 characters total. I'm just doing this:

pawn Code:

stock randNumber()
{
    new szString[13];
    format(szString, sizeof(szString), "%d%d%d%d%d%d", random(9), random(9), random(9), random(9), random(9), random(9));
    return szString;
}

Oh okay. Btw the length is 6, not 12.

I doubled it because I wasn't sure if each "%d" would count as two characters. I'll change it to 7.

Why you use 9? isnt it 10?

0,1,2,3,4,5,6,7,8,9 = 10 not 9

Sorry if im wrong...

[=WoR=Varth]

Yes it's 10. What a stupid I am.

It's 9 because it would be numbers 0-9 and not 1-9. I am getting strings like "840824" so clearly all numbers are working properly.

[PrawkC]

No, it'd be 10.. random(10) would be from 0-9.

Wrong. I am absolutely positive it's 9. I want the numbers 0 - 9 and not 0 - 10. It would mess up my code if one of the digits generated to 10.

[PrawkC]

Sorry to say, but you're wrong.
Give the wiki a read

"Returns A random number ranging from 0 to max-1."

Okay, you got me there. I could of looked but I was too lazy! I'll change it to 10, sorry if I came across as being arrogant.

Heres a more efficient way to get a random string, calling random only once.

pawn Код:

#define RandomEx(%1,%2) (random(%2-%1)+%1)// RandomEx(min, max)

public OnFilterScriptInit()
{
    new
        szStr[11];
    format(szStr, sizeof(szStr), "%i", RandomEx(1000, 9999));
    print(szStr);
    return 1;
}

Failed twice with the format... Its too early.

[marrcko]

or u can use

pawn Код:

format(string,sizeof(string),"%d",100000+random(899999));

[TouR]

6 characters? You could also use

pawn Код:

szString = random(99999)+100000;

Note that this excludes numbers like 000001, if you want those too: pawn Код: new     str[7] format(str, sizeof (str), "%06d", random(1000000)); In this case "format" is the better option as you're using more advanced features.

Thanks for the response, Alex.
