I need to declare an array of pointers to functions like so: extern void function1(void); extern void function2(void); ... void (*MESSAGE_HANDLERS[])(void) = { function1, function2, ... }; However, I want the the array to be declared as constant -- both the data in the array and the pointer to the data. Unfortunately, I do n...
I am trying to create an array starting with today and going back the last 30 days with PHP and I am having trouble. I can estimate but I don’t know a good way of doing it and taking into account the number of days in the previous month etc. Does anyone have a good solution? I can’t get close but I need to make sure it is 100% accurate...
I went looking for this the other day, and thought it should probably be added to StackOverflow's reservoir of questions. How would I go about dynamically allocating a multi-dimensional array? ...
I'm trying to create a function which takes an array as an argument, adds values to it (increasing its size if necessary) and returns the count of items. So far I have: int main(int argc, char** argv) { int mSize = 10; ent a[mSize]; int n; n = addValues(a,mSize); for(i=0;i<n;i++) { //Print values from a }...
I recently ran up against a wall doing some bash shell programming where an associative array would have solved my problems. I googled about features of the Korn shell and learned that it supports associative arrays, so I installed Cygwin's pdksh (public domain korn shell). However, when trying to create an associative array in the pre...
var myArray = new Object(); myArray["firstname"] = "Bob"; myArray["lastname"] = "Smith"; myArray["age"] = 25; Now if I wanted to remove "lastname"?....is there some equivalent of myArray["lastname"].remove()? (I need the element gone because the number of elements is important and I want to keep things clean). Thanks in advance to eve...
I currently am trying to write a python program using scheme semantics so I can later translate it into scheme without relying on a lot of pythonic stuff. I'm trying solve the sliding puzzle problem (where you have 9 slots and 8 tiles arranged in a square) using a*, depth first, and breadth first search algorithm. I did this ~11 years ...
When you have an array like this: int foo[3][2][2]; and you make: int *bar = &foo[0][0][0]; Is this the way it works? *bar == foo[0][0][0]; *(bar+1) == foo[0][0][1]; *(bar+2) == foo[0][1][0]; *(bar+3) == foo[0][1][1]; *(bar+4) == foo[1][0][0]; I'm not sure and have a bit of code dependent on if that works. ...
I made an array in PHP which holds a bucnh of unix timestamps. I'm trying to make a function that will return an array containing the indexes of the 3 largest numbers in that array. For instance, if the largest numbers are located at indexes 3,5 and 8 And if the largest is 5, second largest is 8 and smallest of the three is number 3, ...
By means of a regular expression and Greasemonkey I have an array of results that looks like: choice1, choice2, choice3, choice3, choice1, etc.. My question is how do I tally up the choices so I know how many times choice1 is in the array, choice2 is in the array, etc. if I do not know exactly how many choices there are or what they...
Is it possible in PHP to do something like this? How would you go about writing a function? Here is an example. The order is the most important thing. $customer['address'] = '123 fake st'; $customer['name'] = 'Tim'; $customer['dob'] = '12/08/1986'; $customer['dontSortMe'] = 'this value doesnt need to be sorted'; And I'd like to do som...
I want to create an array with a message. $myArray = array('my message'); But using this code, myArray will get overwritten if it already existed. If I use array_push, it has to already exist. $myArray = array(); // <-- has to be declared first. array_push($myArray, 'my message'); Otherwise, it will bink. Is there a way to make...
The following is a simplified version of what I'm trying to do, because I'm sure you don't want to wade through an entire set of structs and function prototypes for a particle system. float const materials[24][4][4] = {{{...}}}; typedef struct EmitterStruct { float *material[4][4]; } Emitter; typedef struct ParticleStruct { float mater...
Hello, as I am implementing the ICollection-Interface in my class I want to implement the CopyTo-Method and I have to throw an Argument-exception if the array is multidimensional. What is meant by this? The head of my method is this public void CopyTo(MyClass[] array, int arrayIndex) I thought these brackets would mean that the given...
I have two arrays in PHP. The first array ($author_array) is comprised of user_ids in a particular order, like so: (8, 1, 6) The second array ($user_results) is comprised of an array of objects like so: Array ( [0] => stdClass Object ( [ID] => 1 [user_login] => user1 ) [1] => stdClass Obj...
What is the meaning, and where is the Ruby documentation for the syntax of: Array(phrases) which I found browsing the Rails source here: # File actionpack/lib/action_view/helpers/text_helper.rb, line 109 ... 119: match = Array(phrases).map { |p| Regexp.escape(p) }.join('|') I thought that Array.new would normally be used...
I'm trying to run a 3d array but the code just crashes in windows when i run it, here's my code; #include <iostream> using namespace std; int main(){ int myArray[10][10][10]; for (int i = 0; i <= 9; ++i){ for (int t = 0; t <=9; ++t){ for (int x = 0; x <= 9; ++t){ myArray[i][t][x] = i+t...
Hi guys, I tried to make a dynamic 2D array of char as follow: char** ppMapData = (char**)malloc(sizeof(char*)*iMapHeight); for (int i=0; i< iMapHeight; i++) { ppMapData[i] = (char*)malloc(sizeof(char)*iMapWidth); //do something } // do something for (int i=0; i<iMapHeight; i++) free(ppMapData[i]); free(ppMapData); It lo...
So in C#, I can treat a string[] as an IEnumerable<string>. Is there a Java equivalent? ...
This code throws up the compile error given in the title, can anyone tell me what to change? #include <iostream> using namespace std; int main(){ int myArray[10][10][10]; for (int i = 0; i <= 9; ++i){ for (int t = 0; t <=9; ++t){ for (int x = 0; x <= 9; ++x){ for (int y = 0; y <= ...
