Since the latter is quiet easy to check, I'd check that first. To do it, declare randomArray on the heap using dynamic memory allocation rather than on the stack using static memory allocation.

The way its done and you might know this already.. You read an image into a bufferedImage and after that you can get RGB values just by using getRGB(x_value,y_value). Let me know if you need help because i have done image processing in JAVA. Re: HSB without RBG conversion 14 Years Ago by idlackage Thank you! Can't believe I missed the API thing. Re: Multidimensional Arrays by reference? 10 Years Ago by mixelplik Sorry - just found the stupid bug - I used the indexes instead of the loop counters in assigning the values. Re: Lottery using arrays 9 Years Ago by Ancient Dragon I assume the array of winning digits can not contain duplicate numbers -- for example this would be illegal: 7 1 4 7 2 5 because the number 7 appears more than once. If that is correct, then you need to expand the loop on line 12 to check the array to see if the value returned by line 13 already exists in the array. line 15: a[10] accesses … Re: Lottery using arrays 9 Years Ago by phorce Hey, what the problem is asking you is to count the total number of times an element exists inside an array. Assume the following: `A = [1, 2, 3, 4]` `B = [2, 1, 2, 4]` Then you can do the following: `AϵB` This is going to either give you true or false.. Because 2 in B exists in A, 1 exists... Therefore, only having one array does not make … Re: Lottery using arrays 9 Years Ago by DS9596 I'm still not really getting it, I sort of understand what you guys are trying to say but I'm not sure of how to write it. #include <iostream> using namespace std; int main() { int winningDigits[5]; int players; int Matches; int i; int a[9]; for (int i = 0; i<5; i++)… Re: Lottery using arrays 9 Years Ago by DS9596 I don't get how to make them match with each other. Re: Lottery using arrays 9 Years Ago by phorce No, you would just create a `rand` for the users, you would input the user: int player[5]; for(int i=0; (i < 5); i++) { std::cout << "Please enter number" << i; cin >> player[i]; } then you would carry out the comparision. Hope this helps Re: Lottery using arrays 9 Years Ago by Ancient Dragon >I don't get how to make them match with each other. You will need two loops, one inside the other. The outer loop will step through each of the digits in winningDigits array. The inner loop will attempt to find the current digitit in winningDigits in the player array. If a match is found then put that digit in a third array so that you … Re: getimagewidth width to array 9 Years Ago by veedeoo hi, Try reading [One](http://www.smipple.net/snippet/Alex/List%20images%20from%20folder%20via%20PHP%20%28revised%29) and[ two](http://stackoverflow.com/questions/18809992/how-to-get-the-image-with-largest-size-among-all-the-images-on-the-page).
