• java applet - array checking

  - by Dan

  OK so my code is here: http://www.so.pastebin.com/m7V8rQ2n What I want to know... let's say I have an image which I can redraw on tiles... is there a way to check for future tiles so I DON'T go out of bounds of my already defined tile map? Like if I were at the edge of a map... it would NOT let me go past it? Thanks.

• Perl array and hash manipulation using map

  - by somebody

  I have the following test code use Data::Dumper; my $hash = { foo => 'bar', os => 'linux' }; my @keys = qw (foo os); my $extra = 'test'; my @final_array = (map {$hash->{$_}} @keys,$extra); print Dumper \@final_array; The output is $VAR1 = [ 'bar', 'linux', undef ]; Shouldn't the elements be "bar, linux, test"? Why is the last element undefined and how do I insert an element into @final_array? I know I can use the push function but is there a way to insert it on the same line as using the map command? Basically the manipulated array is meant to be used in an SQL command in the actual script and I want to avoid using extra variables before that and instead do something like: $sql->execute(map {$hash->{$_}} @keys,$extra);

• iPhone: Get value in multi-dimentional array

  - by Nic Hubbard

  I have an array that is many levels deep and I am wondering what is the best way to get one of the child element values that is deep in my array. I assume I need to use a recursive method, but what is the best way to do this? Or is there a faster way to do this? The array comes from an XML Parser that I am using which builds everything into an array like this (using NSLog to show the structure): { children = ( { children = ( { children = ( { children = ( ); data = 12; element = AssetID; } ); data = ""; element = "ns1:GetUserIdByUsernameResponse"; } ); data = ""; element = "SOAP-ENV:Body"; } ); data = ""; element = "SOAP-ENV:Envelope"; } What I would like to get at is the AssetID data, which in this case is 12.

• Is it OK to run an array with 22k strings in a PHP code on a shared web host?

  - by kuchikoo

  I'm new to writing code so kindly bear with me if this is a very noobish question. A couple of days back I asked a question about a PHP code that matches the the query entered by users on my website to an array stored within the PHP code and displays the matched queries. Here is the code I'm talking about Now I've ended up with a rather large list (over 22k) of strings that have to be stored in the array. Is it ok to run it like this? I'm hosting the site on a shared hostgator package, will this cause my site to crash? I don't know too much about DBs but can I somehow store this on MySQL instead of having it in the code?

• Determining whether one array contains the contents of another array in ruby

  - by Andrew Grimm

  In ruby, how do I test that one array not only has the elements of another array, but contain them in that particular order? correct_combination = [1, 2, 3, 4, 5] [1, 5, 8, 2, 3, 4, 5].function_name(correct_combination) # => false [8, 10, 1, 2, 3, 4, 5, 9].function_name(correct_combination) # => true I tried using include, but that is used to test whether [1,2,3].include?(2) is true or not.

  I have an Array, Sample: $array { [0] { [something]=1; [something2]=2; } [1] { [something]=2; [something2]=4; } [2] { [something]=5; [something2]=2; } } I want to order the array based on the key something; So it will look like: $array { [0] { [something]=5; [something2]=2; } [1] { [something]=2; [something2]=4; } [2] { [something]=1; [something2]=2; } }

• How to move positions within an array?

  - by Jade Mulholland

  A program that simply moves array elements. Two variables: userInputVariable and blankSpaceVariable. I have a 2D array named table. Defined as table[userInputVariable + 1][6] I am printing out this array in a table format, and the far left column is numbered by whatever number the user entered at the beginning of the program. I then ask the user where they would like to enter a blank space within the array. This blank space acts like a divider for all the other information in the array. For example, if the user enters 10 at the start for the userInputVariable, and then enters 5 for the blank space. Once printed, the numbers should go like this: 1, 2, 3, 4, --, 5, 6, 7, 8, 9, 10. My plan has been to create a for loop and try to move all the numbers in the array back a position starting from the blank space variable. What I currently have, but does not work: for (int i = blankSpaceVariable; i < table.length - 1; i++) { table[i] = table[i + 1]; } table[blankSpaceVariable] = "--"; With my current code, the numbers go like this: 1, 2, 3, 4, 6, 7, 8, 9, 10 Tried completing this a few different ways also, but the other info within my 2D array didn't move with the numbers. So I thought that this approach can hopefully move all the info within my 2D array down, and make way for a blank section. All help is greatly appreciated!

• Java: most efficient way to defensively copy an int[]?

  - by Jason S

  I have an interface DataSeries with a method int[] getRawData(); For various reasons (primarily because I'm using this with MATLAB, and MATLAB handles int[] well) I need to return an array rather than a List. I don't want my implementing classes to return the int[] array because it is mutable. What is the most efficient way to copy an int[] array (sizes in the 1000-1000000 length range) ? Is it clone()?

• dreferencing 2 d array

  - by ashish-sangwan

  Please look at this peice of code :- #include<stdio.h> int main() { int arr[2][2]={1,2,3,4}; printf("%d %u %u",**arr,*arr,arr); return 0; } When i compiled and executed this program i got same value for arr and *arr which is the starting address of the 2 d array. For example:- 1 3214506 3214506 My question is why does dereferencing arr ( *arr ) does not print the value stored at the address contained in arr ?

• XCode Obj-C: Make new NSArray from one key each out of an Array of Dictionaries

  - by user323772

  This actually could be a multipart question. But here's the first part ... I have an array (actually in a plist) of dictionaries. Each dictionary has 3 keys in it: (title), (points), and (description). I am trying to make a NEW array with the values of the key "title" from each dictionary in that first array. Let me explain WHY I am doing this and maybe that will provide a better all around explanation. I am trying to let people pick from a pre-determined list. Heck, if this was a web page it would be very simple since all I really care about are the "points" and the "Title". On a web site I could simply do a drop down combo-box with the "points" being the value and the title being the text for each row. But this is not a web page. So what I am trying to do here is pop out a modal picker when they click the text field. The modal picker shows the alphabetical ordered "titles" from our new array. And whichever one they select, it closes the modal view and assigns that "title" text to the UITextField which cannot be edited by the user. I have some code to get my modal picker to pop out. But I need to feed it an array of just the "titles" of each dictionary in my real array. Thanks in advance (and yes I am a newbie)

• How do I print array values in a range when values are supplied?

  - by dcp3450

  My php reads in xml and I want to ouput the values within a given range. I have no way of knowing the size of the array or the range. However, I do know where to start; I have a $key that holds my current location. I also know where to stop; I have the word "ENDEVENTS" between each set. I want to get the values from my current position ($key) to my end position ("ENDEVENTS"). for example i may have an array set like this: Array( [0]=1 [1]=apple [2]=straw [3]=bike [4]=ENDEVENTS [5]=15 [6]=hair [7]=shirt [8]=nose [9]=kiwi [10]=ENDEVENTS ) My code knows when I'm on 15 (in this example $key=5). I want to print 6 through 9. I tried using foreach but it's thats causing issues with what I'm trying to produce. Any ideas?

• : for displaying all elements in a multidimensional array in python 3.1.

  - by Leif Andersen

  I have a multidimensional array in python like: arr = [['foo', 1], ['bar',2]] Now, if I want to print out everything in the array, I could do: print(arr[:][:]) Or I could also just do print(arr). However, If I only wanted to print out the first element of each box (for arr, that would be 'foo', 'bar'), I would imagine I would do something like: print(arr[:][0]) however, that just prints out the first data blog (['foo', 1]), also, I tried reversing it (just in case): print(arr[0][:]) and I got the same thing. So, is there anyway that I can get it to print the first element in each tuple (other than: for tuple in arr: print(tuple[0]) )? Thanks.

• why doesnt this program print?

  - by Alex

  What I'm trying to do is to print my two-dimensional array but i'm lost. The first function is running perfect, the problem is the second or maybe the way I'm passing it to the "Print" function. #include <stdio.h> #include <stdlib.h> #define ROW 2 #define COL 2 //Memory allocation and values input void func(int **arr) { int i, j; arr = (int**)calloc(ROW,sizeof(int*)); for(i=0; i < ROW; i++) arr[i] = (int*)calloc(COL,sizeof(int)); printf("Input: \n"); for(i=0; i<ROW; i++) for(j=0; j<COL; j++) scanf_s("%d", &arr[i][j]); } //This is where the problem begins or maybe it's in the main void print(int **arr) { int i, j; for(i=0; i<ROW; i++) { for(j=0; j<COL; j++) printf("%5d", arr[i][j]); printf("\n"); } } void main() { int *arr; func(&arr); print(&arr); //maybe I'm not passing the arr right ? }

• Multiple value array

  - by Ant..

  I am new to jScript and have written this code [which works perfectly]. Its purpose is to test that the term for the amount of loan is not exceeded. Can the process be consolidated into one array where you pass the loan amount which returns the term based on the range i.e. 6000 to 7000 = 96 function TestMaxTerm() { var LnAmt = 14000 //Testing Purposes var Term = 0 //Testing Purposes if (LnAmt > 0 && LnAmt <= 1000){Term = 0;} if (LnAmt > 1000 && LnAmt <= 2000){Term = 1;} if (LnAmt > 2000 && LnAmt <= 3000){Term = 2;} if (LnAmt > 3000 && LnAmt <= 4000){Term = 3;} if (LnAmt > 4000 && LnAmt <= 5000){Term = 4;} if (LnAmt > 5000 && LnAmt <= 6000){Term = 5;} if (LnAmt > 6000 && LnAmt <= 7000){Term = 6;} if (LnAmt > 7000 && LnAmt <= 8000){Term = 7;} if (LnAmt > 8000 && LnAmt <= 9000){Term = 8;} if (LnAmt > 9000 && LnAmt <= 10000){Term = 9;} if (LnAmt > 10000 && LnAmt <= 11000){Term = 10;} if (LnAmt > 11000 && LnAmt <= 12000){Term = 11;} if (LnAmt > 11000){Term = 12;} //Obtain Maximum Term for Loan Amount var MaxTerm = new Array(); MaxTerm[0] = 24; MaxTerm[1]=36; MaxTerm[2] = 48; MaxTerm[3] = 60; MaxTerm[5] = 72; MaxTerm[5]=84; MaxTerm[6] = 96; MaxTerm[7] = 108; MaxTerm[8] = 120; MaxTerm[9]=132; MaxTerm[10] = 164; MaxTerm[11] = 176; MaxTerm[12] = 420; var text = MaxTerm[Term]; alert(text); }

• In C, during step by step debugging in a function, how can i view the content of an array in the "Autos?" window along with the other variables?

  - by AppsAndGo

  I'm using VS 2012, and I'm working on a bubble sort. After searching I found a nifty trick to see the content of the array in the "Watch 1" tab, (How to view contents of an array while debugging in Code Blocks?), but going from "watch 1" to "Autos" every step to see what's changing in the array isn't practical at all. How can i see the array content within "Autos" along side my other changing variables, where i need it to show?

• How can I initialize a 2d array in Perl?

  - by Mark

  How do I initialize a 2d array in perl? I am trying the following code: 0 use strict; 10 my @frame_events = (((1) x 10), ((1) x 10)); 20 print "$frame_events[1][1]\n"; but it gives the following error: Can't use string ("1") as an ARRAY ref while "strict refs" in use at ./dyn_pf.pl line 20. This syntax only seems to initialize a 1d array as print "$frame_events[1]\n" works. Though perl doesn't give any error during the assignment.

• returning values from function or method multiple times by only calling the class once

  - by Sokhrat Sikar

  I have a members.php file that shows my websites members. I echo members name by using foreach method. A method of Members class returns an array, then I use foreach loop in the members.php file to echo the members. I am trying to aovid writing php code in my members.php file. Is there a way to avoid using foreach inside members.php file? For example, is it possible to return value from a method couple of times? (by only calling the object once). Just like how we normally call the functions? This question doesn't make sense, but I am just trying to see if there is a away around this issue?
