• list arrays in Drupal form

  - by bert

  Is there a better way to find all form elements in a Drupal form than doing a print_r($form)? This dumps excessive amount of information and it is no obvious what to look for.

• Nested loop traversing arrays

  - by alecco

  There are 2 very big series of elements, the second 100 times bigger than the first. For each element of the first series, there are 0 or more elements on the second series. This can be traversed and processed with 2 nested loops. But the unpredictability of the amount of matching elements for each member of the first array makes things very, very slow. The actual processing of the 2nd series of elements involves logical and (&) and a population count. I couldn't find good optimizations using C but I am considering doing inline asm, doing rep* mov* or similar for each element of the first series and then doing the batch processing of the matching bytes of the second series, perhaps in buffers of 1MB or something. But the code would be get quite messy. Does anybody know of a better way? C preferred but x86 ASM OK too. Many thanks! Sample/demo code with simplified problem, first series are "people" and second series are "events", for clarity's sake. (the original problem is actually 100m and 10,000m entries!) #include <stdio.h> #include <stdint.h> #define PEOPLE 1000000 // 1m struct Person { uint8_t age; // Filtering condition uint8_t cnt; // Number of events for this person in E } P[PEOPLE]; // Each has 0 or more bytes with bit flags #define EVENTS 100000000 // 100m uint8_t P1[EVENTS]; // Property 1 flags uint8_t P2[EVENTS]; // Property 2 flags void init_arrays() { for (int i = 0; i < PEOPLE; i++) { // just some stuff P[i].age = i & 0x07; P[i].cnt = i % 220; // assert( sum < EVENTS ); } for (int i = 0; i < EVENTS; i++) { P1[i] = i % 7; // just some stuff P2[i] = i % 9; // just some other stuff } } int main(int argc, char *argv[]) { uint64_t sum = 0, fcur = 0; int age_filter = 7; // just some init_arrays(); // Init P, P1, P2 for (int64_t p = 0; p < PEOPLE ; p++) if (P[p].age < age_filter) for (int64_t e = 0; e < P[p].cnt ; e++, fcur++) sum += __builtin_popcount( P1[fcur] & P2[fcur] ); else fcur += P[p].cnt; // skip this person's events printf("(dummy %ld %ld)\n", sum, fcur ); return 0; } gcc -O5 -march=native -std=c99 test.c -o test

• Allocating 32-bit integer arrays in 64-bit machines

  - by Shredderroy

  I have a 64-bit i7 machine. Suppose I allocate memory for n 32-bit integers. How many physical registers will actually be used in the allocation: n, or n/2? I tried to write the following simple programme to find out. #include <iostream> #include <cstdlib> using namespace std; int main (int argc, char *argv[]) { int a[4]; cout << &a[0] << "\t" << &a[3] << endl; cin.ignore (1); return 0; } // End main () The output is: 0018FA04 0018FA10 They seem further apart than they should be. Why aren't the addresses 04 and 07? And does this mean that the system is actually allocating four (or more) integers, instead of packing the four 32-bit integers into two 64-bit registers? Thanks in advance for your help.

• sorting char* arrays

  - by skazhy

  Hi! I have a datastructure struct record { char cont[bufferSize]; record *next; }; When I add new records to this structure, I want them to be sorted alphabetically. I made this function, that adds record in the right place (by alphabet) in the linked list: record *start=NULL, *p, *x; void recAdd(char*temp) { p = new record; temp[strlen(temp)] = '\0'; for (int j=0;j<bufferSize;j++) p->cont[j] = temp[j]; if (start==NULL) start=p; else { x=start; int c=0; while (recComp(x->cont,p->cont) <= 0 && x->next != NULL) { x=x->next; c++; } if (c == 0) { p->next=start; start=p; } else { x=start; for (int i=0;i<c;i++) x=x->next; p->next=x->next; x->next=p; } } for (int j=0;j<bufferSize;j++) temp[j] = NULL; }; But somehow it doesn't sort things right. What is wrong with my function?

• ActionScript arrays being automatically set to other values

  - by nababa

  I am making a flash game, in each round, the player will chose either True or False. The decision of each round will be stored in an array. That is, it looks like {true, false, true, false}.. When the user clicks the "Debrief“ button, the eventlistener will be called and the game will go to the debriefing part. It will read the array mentioned before. However, the array values are all "false". I am very sure that the array has not being touched in between. So, any ideas about why the array is set to false mysteriously?

• Struct arrays in C

  - by ThomasTheTankEngine

  Hi I'm having trouble trying to initializing each element of the struct array. When I try and assign the value ZERO to both 'bSize' and 'msgs', it doesn't work as it errors out when i get to malloc. In the printf statement it prints a -1852803823 number. Excuse the messy code as i'm playing around trying to figure it out. struct message{ int *data; int bSize; int msgs; }; int main(int argc, char *argv[]) { ..... } void getSchedFile (FILE *file, int **schd) { struct message sMsg[nodeCount]; const int pakSize = 6; // Iniitialise message buffer for (int i=0; i<nodeCount; i++){ sMsg[i].bSize = 0; sMsg[i].msgs = 0; printf("bSize %d\n",sMsg[i].bSize); } /* Get the number of bytes */ fseek(file, 0L, SEEK_SET); int time; while((fscanf(file, "%d", &time)) != EOF){ int src; fscanf(file, "%d", &src); // get source node id // These are here for easier reading code int aPos = sMsg[src].bSize; int nMsg = sMsg[src].msgs; printf("size %d\n", sMsg[src].bSize); if (sMsg[src].bSize==0){ sMsg[src].data = malloc( pakSize * sizeof(int)); }else{ sMsg[src].data = realloc(sMsg[src].data, (aPos+pakSize)*sizeof(int)); }

• Example of [NSDictionary getObjects:andKeys:]

  - by eagle

  I couldn't find a working example of the method [NSDictionary getObjects:andKeys:] on Google. The only link I could find, doesn't compile. I provided the errors/warnings here in case someone is searching for them. The documentation says that it returns a C array. NSDictionary *myDictionary = ...; id objects[]; // Error: Array size missing in 'objects' id keys[]; // Error: Array size missing in 'keys' [myDictionary getObjects:&objects andKeys:&keys]; for (int i = 0; i < count; i++) { id obj = objects[i]; id key = keys[i]; } .

• ASP.NET MVC - Pass array object as a route value within Html.ActionLink(...)

  - by Mike

  I have a method that returns an array (string[]) and I'm trying to pass this array of strings into an Action Link so that it will create a query string similar to: /Controller/Action?str=val1&str=val2&str=val3...etc But when I pass new { str = GetStringArray() } I get the following url: /Controller/Action?str=System.String%5B%5D So basically it's taking my string[] and running .ToString() on it to get the value. Any ideas? Thanks!

• Sorting a Multidimensional array...

  - by sologhost

  I need to sort an array that can look like this: $array[4][0] = array('id' => 1, 'value' => 2); $array[3][2] = array('id' => 0, 'value' => 3); $array[4][1] = array('id' => 1, 'value' => 0); $array[1][3] = array('id' => 2, 'value' => 1); $array[1][1] = array('id' => 3, 'value' => 0); $array[3][0] = array('id' => 2, 'value' => 1); $array[3][1] = array('id' => 1, 'value' => 0); $array[1][2] = array('id' => 3, 'value' => 2); $array[1][0] = array('id' => 2, 'value' => 1); $array[2][1] = array('id' => 0, 'value' => 2); $array[2][4] = array('id' => 3, 'value' => 1); But needs to be sorted and returned as this: $array[1][0] = array('id' => 2, 'value' => 1); $array[1][1] = array('id' => 3, 'value' => 0); $array[1][2] = array('id' => 3, 'value' => 2); $array[1][3] = array('id' => 2, 'value' => 1); $array[2][1] = array('id' => 0, 'value' => 2); $array[2][4] = array('id' => 3, 'value' => 1); $array[3][0] = array('id' => 2, 'value' => 1); $array[3][1] = array('id' => 1, 'value' => 0); $array[3][2] = array('id' => 0, 'value' => 3); $array[4][0] = array('id' => 1, 'value' => 2); $array[4][1] = array('id' => 1, 'value' => 0); Can anyone help me? It needs to sort both indexes of the array from lowest to highest index value. Sounds simple enough, but I'm having the hardest time trying to figure this out, while still keeping the values intact. Please help someone...

• Passing an array argument from Excel VBA to a WCF service

  - by PrgTrdr

  I'm trying to pass an array as an argument to my WCF service. To test this using Damian's sample code, I modified GetData it to try to pass an array of ints instead of a single int as an argument: using System; using System.ServiceModel; namespace WcfService1 { [ServiceContract] public interface IService1 { [OperationContract] string GetData(int[] value); [OperationContract] object[] GetSomeObjects(); } } using System; namespace WcfService1 { public class Service1 : IService1 { public string GetData(int[] value) { return string.Format("You entered: {0}", value[0]); } public object[] GetSomeObjects() { return new object[] { "String", 123, 44.55, DateTime.Now }; } } } Excel VBA code: Dim addr As String addr = "service:mexAddress=""net.tcp://localhost:7891/Test/WcfService1/Service1/Mex""," addr = addr + "address=""net.tcp://localhost:7891/Test/WcfService1/Service1/""," addr = addr + "contract=""IService1"", contractNamespace=""http://tempuri.org/""," addr = addr + "binding=""NetTcpBinding_IService1"", bindingNamespace=""http://tempuri.org/""" Dim service1 As Object Set service1 = GetObject(addr) Dim Sectors( 0 to 2 ) as Integer Sectors(0) = 10 MsgBox service1.GetData(Sectors) This code works fine with the WCF Test Client, but when I try to use it from Excel, I have this problem. When Excel gets to the service1.GetData call, it reports the following error: Run-time error '-2147467261 (80004003)' Automation error Invalid Pointer It looks like there is some incompatibility between the interface specification and the VBA call. Have you ever tried to pass an array from VBA into WCF? Am I doing something wrong or is this not supported using the Service moniker?

• Java native methods issues with SUN JVM (jdk1.5.0_14) and multi-core CPU’s

  - by Mattias Arnersten

  We are hosting an application on SUN JVM that handles a lot of XML parsing using Jaxb. The application is parsing the XML fine using JRockit 5 but when using the SUN JVM the JVM spends a majority of it’s time on native methods such as java-lang.System.arraycopy, java.lang.String.intern and java.lang.ClassLoader.getPackage. The CPU load is approx. 60% higher when using SUN JVM compared with JRockit. Even stranger is that when we only run the application server using one core (in WMWare) the problem disappears. Has anyone experienced the same behavior? Mattias Arnersten

• I need to take an array of three lines in a text file and sort them base on the first line in Java.

  - by Cory

  I need to take an array of three lines in a text file and sort them base on the first line in Java. I also need to manipulate this as well and then print to screen. I have a test file that is formatted like this: 10 Michael Jackson 12 Richard Woolsey I need to input this from a text file and then rearrange it based on the number associated with the name. At that point, I need to use a random number generator and assign a variable based on the random number to each name. Then I need to print to screen the variable I added and the name in a different format. Here is an example of the output: 12: Woolsey, Richard Variable assigned 10: Jackson, Michael Other variable assigned I highly appreciate any help. I ask because I do not really know how to input the three lines as one variable and then manipulate later on in the program. Thanks, Cory

• Issue with dynamic array Queue data structure with void pointer

  - by Nazgulled

  Hi, Maybe there's no way to solve this the way I'd like it but I don't know everything so I better ask... I've implemented a simple Queue with a dynamic array so the user can initialize with whatever number of items it wants. I'm also trying to use a void pointer as to allow any data type, but that's the problem. Here's my code: typedef void * QueueValue; typedef struct sQueueItem { QueueValue value; } QueueItem; typedef struct sQueue { QueueItem *items; int first; int last; int size; int count; } Queue; void queueInitialize(Queue **queue, size_t size) { *queue = xmalloc(sizeof(Queue)); QueueItem *items = xmalloc(sizeof(QueueItem) * size); (*queue)->items = items; (*queue)->first = 0; (*queue)->last = 0; (*queue)->size = size; (*queue)->count = 0; } Bool queuePush(Queue * const queue, QueueValue value, size_t val_sz) { if(isNull(queue) || isFull(queue)) return FALSE; queue->items[queue->last].value = xmalloc(val_sz); memcpy(queue->items[queue->last].value, value, val_sz); queue->last = (queue->last+1) % queue->size; queue->count += 1; return TRUE; } Bool queuePop(Queue * const queue, QueueValue *value) { if(isEmpty(queue)) return FALSE; *value = queue->items[queue->first].value; free(queue->items[queue->first].value); queue->first = (queue->first+1) % queue->size; queue->count -= 1; return TRUE; } The problem lies on the queuePop function. When I call it, I lose the value because I free it right away. I can't seem to solve this dilemma. I want my library to be generic and modular. The user should not care about allocating and freeing memory, that's the library's job. How can the user still get the value from queuePop and let the library handle all memory allocs/frees?

• Find largest rectangle containing all zero's in an N X N binary matrix

  - by Rajendra

  Given an N X N binary matrix (containing only 0's or 1's). How can we go about finding largest rectangle containing all 0's? Example: I 0 0 0 0 1 0 0 0 1 0 0 1 II->0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 <--IV 0 0 1 0 0 0 IV is a 6 X 6 binary matrix, return value in this case will be Cell 1: (2, 1) and Cell 2: (4, 4). Resulting sub-matrix can be square or rectangle. Return value can be size of the largest sub-matrix of all 0's also, for example, here 3 X 4.
