  • Javascript algorithm to find elements in array that are not in another array

    - by Tauren
    I'm looking for a good algorithm to get all the elements in one array that are not elements in another array. So given these arrays: var x = ["a","b","c","t"]; var ?????????y = [???????"d","a","t","e","g"]; I want to end up with this array: var z = ["d","e","g"]; I'm using jquery, so I can take advantage of $.each() and $.inArray(). Here's the solution I've come up with, but it seems like there should be a better way. // goal is to get rid of values in y if they exist in x var x = ["a","b","c","t"]; var y = ["d","a","t","e","g"]; var z = []; $.each(y, function(idx, value){ if ($.inArray(value,x) == -1) { z.push(value); } }); ?alert(z); // should be ["d","e","g"] Here is the code in action. Any ideas?

  • How to create an array of buttons in C++

    - by mangoman13
    Hi, I'm using C++ in VS2005 and have an 8x8 grid of buttons on a form. I want to have these buttons in an array, so when I click on any of them it will open the same event handler (I think that is what they are called), but I will know the index of which one was clicked on. I know how to do this in VB and C#, but I can't seem to figure it out with C++ Right now I have all my buttons labelled by their location, i.e. b00, b10, b21, etc. So I think what I am looking for is a way to do something like this: Button b[8][8]; //this causes me errors (error C2728: 'System::Windows::Forms::Button' : a native array cannot contain this managed type) and (error C2227: left of '->{ctor}' must point to class/struct/union/generic type) void Assignment(){ b[0][0] = b00; b[1][0] = b10; ... } and then in form1.h: private: System::Void b_Click(System::Object^ sender, System::EventArgs^ e) { //somehow read the coordinates into variables x and y //do something based on these values } Any help would be appreciated. Also let me know if I am going in the complete wrong direction with this. Thanks!

  • PHP - uninitialized array offset

    - by kimmothy16
    Hey everyone, I am using PHP to create a form with an array of fields. Basically you can add an unlimited number of 'people' to the form and each person has a first name, last name, and phone number. The form requires that you add a phone number for the first person only. If you leave the phone number field blank on any others, the handler file is supposed to be programmed to use the phone number from the first person. So, my fields are: person[] - a hidden field with a value that is this person's primary key. fname[] - an input field lname[] - an input field phone[] - an input field my form handler looks like this: $people = $_POST['person'] $counter = 0; foreach($people as $person): if(phone[$counter] == '') { // use $phone[0]'s phone number } else { // use $phone[$counter] number } $counter = $counter + 1; endforeach; PHP doesn't like this though, it is throwing me an Notice: Uninitialized string offset error. I debugged it by running the is_array function on people, fname, lname, and phone and it returns true to being an array. I can also manually echo out $phone[2], etc. and get the correct value. I've also ran is_int on the $counter variable and it returned true, so I'm unsure why this isn't working as intended? Any help would be great!

  • Translating 3-dimensional array reference onto 1-dimensional array

    - by user146780
    If there is an array of ar[5000] then how could I find where element [5][5][4] would be if this was a 3 dimensional array? Thanks I'm mapping pixels: imagine a bimap of [768 * 1024 * 4] where would pixel [5][5][4] be? I want to make this: static GLubyte checkImage[checkImageHeight][checkImageWidth][4]; static GLuint texName; bool itt; void makeCheckImage(void) { Bitmap *b = new Bitmap(L"c:/boo.png"); int i, j, c; Color cul; for (i = 0; i < checkImageHeight; i++) { for (j = 0; j < checkImageWidth; j++) { b->GetPixel(j,i,&cul); checkImage[i][j][0] = (GLubyte) cul.GetR(); checkImage[i][j][1] = (GLubyte) cul.GetG(); checkImage[i][j][2] = (GLubyte) cul.GetB(); checkImage[i][j][3] = (GLubyte) cul.GetA(); } } delete(b); } work without making a multidimensional array. width = 512, height = 1024....

  • Switch two items in associative array PHP

    - by user280381
    Example: $arr = array('apple'='sweet','grapefruit'='bitter','pear'='tasty','banana'='yellow'); I want to switch the positions of grapefruit and pear, so the array will become 'apple'='sweet','pear'='tasty','grapefruit'='bitter','banana'='yellow') I know the keys and values of the elements I want to switch, is there an easy way to do this? Or will it require a loop + creating a new array? Thanks

  • c++ optimize array of ints

    - by a432511
    I have a 2D lookup table of int16_t. int16_t my_array[37][73] = {{**DATA HERE**}} I have a mixture of values that range from just above the range of int8_t to just below the range of int8_t and some of the values repeat themselves. I am trying to reduce the size of this lookup table. What I have done so far is split each int16_t value into two int8_t values to visualize the wasted bytes. int8_t part_1 = original_value >> 4; int8_t part_2 = original_value & 0x0000FFFF; // If the upper 4 bits of the original_value were empty if(part_1 == 0) wasted_bytes_count++; I can easily remove the zero value int8_t that are wasting a byte of space and I can also remove the duplicate values, but my question is how do I do remove those values while retaining the ability to lookup based on the two indices? I contemplated translating this into a 1D array and adding a number following each duplicated value that would represent the number of duplicates that were removed, but I am struggling with how I would then identify what is a lookup value and what is a duplicate count. Also, it is further complicated by stripping out the zero int8_t values that were wasted bytes. EDIT: This array is stored in ROM already. RAM is even more limited than ROM so it is already stored in ROM. EDIT: I am going to post a bounty for this question as soon as I can. I need a complete answer of how to store the information AND retrieve it. It does not need to be a 2D array as long as I can get the same values. EDIT: Adding the actual array below:

  • In C, is it possible do free only an array first ou last position?

    - by user354959
    Hi there! I've an array, but I don't need its first (or last) position. So I point a new variable to the rest of the array, but I should free the array first/last position. For instance: p = read_csv_file(); q = p + 1; // I don't need the first CSV file field // Here I'd like to free only the first position of p return q; Otherwise I've to memcpy the array to other variable, excluding the first position, and then free the original array. Like this: p = read_csv_file(); q = (int*) malloc(sizeof(int) * (SOME_SIZE - 1)); memcpy(q, p+1, sizeof(int) * (SOME_SIZE - 1)); free(p); return q; But then I'll have the overhead of copying all the array. Is this possible to only free a single position of an array?

  • Can I use array_push on a SESSION array in php?

    - by zeckdude
    I have an array that I want on multiple pages, so I made it a SESSION array. I want to add a series of names and then on another page, I want to be able to use a foreach loop to echo out all the names in that array. This is the session: $_SESSION['names'] I want to add a series of names to that array using array_push like this: array_push($_SESSION['names'],$name); I am getting this error: array_push() [function.array-push]: First argument should be an array Can I use array_push to put multiple values into that array? Or perhaps there is a better, more efficient way of doing what I am trying to achieve?

  • What is array portability?

    - by bobo
    From this page: http://www.doctrine-project.org/documentation/manual/1_2/en/working-with-models#dealing-with-relations:creating-related-records You can see that it says $obj['property']; is the recommended way of referring to an object's property in Doctrine for array portability purposes. I never heard about this term before and google did not come up with useful result. What is that?

  • Changing array values in a VBA dictionary

    - by Pawan Jain
    Hi I have a piece of code that does not seem to do what it is expected to do. VBA Arrays are mutable by all means, but it seems that when they are stored into a Dictionary as values of some keys, they are not mutable anymore. Any ideas? Sub foo() Dim mydict As New Dictionary mydict.Add "A", Array(1, 2, 3) MsgBox mydict("A")(1) ' The above shows 2, which is fine mydict("A")(1) = 34 MsgBox mydict("A")(1) ' The above also shows 2, which is not fine End Sub

  • Creating array with constant

    - by wrongusername
    I was working on a program in Netbeans on Linux using a gcc compiler when, upon switching to Visual C++ on Windows 7, the code failed to compile as Visual C++ says it expected constant expression on several lines. On Netbeans, I simply did something similar to char name[fullName.size()];, while on Visual C++, I tried, among other things, const int position = fullName.size(); char Name[position]; How can I create a constant to use for the array?

  • weird array syntax

    - by dnagirl
    I'm trying to figure how a function I've been given works -- or rather doesn't work. The problematic areas include array notation like this: $small[$end[$i]{0}] I think the idea is to append "0" to the value of $end[$i] and use that for the index of $small. But it doesn't work in PHP5.3. Is this a deprecated syntax and is it trying to do what I think it is?
