So, i was thinking if its possible to run for loop randomly... like instead of for( i =0; i< max; i++)

instead of i++, making it access random element, but while remaining within max

Then how will the condition ever be fulfilled? It will just create an infinite loop.

e.g:

i have this thingy: myarray[5];

so what we usually do is, for(int i=0; i< 5; i++) myarray[i] ... where i is respectively 0, 1, 2, 3, 4
What i want to do is somehow we can make that for loop run till it reaches 4, but the i value shouldn't be 0, 1, 2, 3, 4 but something like 4, 1, 3, 0, 2...

What i had in mind was making it something like this:

PHP код:

    new max, myarray[max], mycount;
    while(mycount < max)
    {
        new i = random(max);
        myarray[i] ...
        mycount++;
    } 


Any harm with this one?

But what if the random is instantly 4, like the loop start and the random number that will come is 4, which 4 is max, will the loop stop earlier without going through 2/1/0..?

PHP код:

 new max, myarray[max], mycount; 
    while(mycount < max) 
    { 
        new i = random(max); 
        myarray[i] ... 
        mycount++; 
    } 


Lemme explain this piece of code... it means, the cycle will run till mycount has not reached max, and mycount is incrementing everytime it loops, meaning even if i is 4, the loop wont stop as the while loop is taking in consideration mycount, not i.

This is my version xD

PHP код:

randomEx(min, max, ...) // credits Dayrion : ...
{
    max++;
    new
        maxarg = numargs()-1,
        nb = random(max - min) + min;
    while(maxarg+1 != 2)
    {
        if(nb == getarg(maxarg))
        {
            maxarg = numargs()-1;
            nb = random(max - min) + min;
        }
        else
            maxarg--;
    }
    
    return nb;
}
main()
{
    myarray[randomEx(1, 5)];
    myarray[randomEx(1, 5, 5)];
    myarray[randomEx(1, 5, 5, 4)];
    myarray[randomEx(1, 5, 5, 4, 3)];
    myarray[randomEx(1, 5, 5, 4, 3, 2)];
}

Here's a solution

1- make a local array same size as your whole loop.
2- Randomly feel them with unique indexes 0 to max
3- make a normal loop, but use j=array[i] and use that
4- now you've made a proper random loop index.
