How to randomize array elements ?

[[Deleted]]

i have an array containing 30 elements ?

How to interchange their positions in array randomly  everytime i call a function ?

at init:

MathSrand(GetTickCount());

in the "loop":

int index= MathRand()%30;

so you change the access to the array, not the values at its positions.
