CCRandom_0_1() generate the same number

i use CCRandom_0_1() to generate a random number, as suggested in the book 'learn-iphone-and-ipad-with-cocos2d' but it seems the function generates the same number. 

    int ran1 = ((int) (CCRANDOM_0_1() * 5)) + 1;
    int ran2 = ran1;
    while (ran2 == ran1) {
        ran2 = ((int) (CCRANDOM_0_1() * 5)) + 1;
    }

here is the code where i want to generate 2 different integer from 1 to 5. but the console is always

Is there anyway i can seed it according to time(mini second something), or is there any other functions to use?

Please give me example code. I didn't learn c or c++ before. Thank you.

If you want different values every time you use the code, then you must seed the random generator. The most popular way is to call srandom(time(NULL)) before using CCRANDOM
