I want to randomize number in each element of array in a variabel. I currently use srand() function. But, with this function i could get a same number in two or more element of array.

the output of my program is
number[0]=6
number[1]=3
number[2]=8
number[3]=3

See, number[1] and number[3] has same value. How to prevent this thing happen?

You can imitate a poor man's implementation of set by iterating through the array to find out whether the next number is in the array or not before adding it to the array. – R Sahu Feb 18 '15 at 03:36

Also, your probably use rand() and not srand() to generate the random elements. – jschultz410 Feb 18 '15 at 03:36
Well that's the thing with randomness, you can get two results that are the same, you can even get *all* results being the same. – Some programmer dude Feb 18 '15 at 03:37
