• How do I use multiple arguments from an array to construct an execl() call in C?

  - by chucknelson

  I have a string array in C named args[] - now how can I use this list of arguments to construct a proper call to execl()? So if the array contains: {"/bin/ls","ls","-a","-l"} ...how can I eventually construct an execl() call that is: execl("/bin/ls","ls","-a","-l",NULL); I must be thinking about this wrong, as I can't find anything online, just talk about defining functions that can take a variable number of arguments.

• How to convert List<int> to string[]?

  - by George Edison

  I need an easy way to convert a List<int> to a string array. I have: var the_list = new List<int>(); the_list.Add(1); the_list.Add(2); the_list.Add(3); string[] the_array = new string[the_list.Count]; for(var i = 0 ; i < the_array.Count; ++i) the_array[i] = the_list[i].ToString(); ...which looks to be very ugly to me. Is there an easier way? Note: I'm looking for an easier way - not necessarily a faster way.

• Rand(); with exclusion to and already randomly generated number..?

  - by Stefan

  Hey, I have a function which calls a users associated users from a table. The function then uses the rand(); function to chose from the array 5 randomly selected userID's however!... In the case where a user doesnt have many associated users but above the min (if below the 5 it just returns the array as it is) then it gives bad results due to repeat rand numbers... How can overcome this or exclude a previously selected rand number from the next rand(); function call. Here is the section of code doing the work. Bare in mind this must be highly efficient as this script is used everywhere. $size = sizeof($users)-1; $nusers[0] = $users[rand(0,$size)]; $nusers[1] = $users[rand(0,$size)]; $nusers[2] = $users[rand(0,$size)]; $nusers[3] = $users[rand(0,$size)]; $nusers[4] = $users[rand(0,$size)]; return $nusers; Thanks in advance!

• Why can't I create an array with size determined by a global variable?

  - by ashish yadav

  Why does the array a not get initialized by global variable size? #include<stdio.h> int size=5; int main() { int a[size]={1,2,3,4,5}; printf("%d",a[0]); return 0; } The compilation error is shown as "variable-sized object may not be initialized". According to me the array should get initialized by size.

• foreach with an array of stdclass objects

  - by Jared Steffen

  So, what I want to do is quite simple in my mind. I have an array that consists solely of four objects. I want to create a loop that will echo an attribute of each object in the array. The only success I've had, however, is echoing every object and every property of the objects. I've never dealt with objects so this is probably the TRUE root of the problem. There's been a few revisions but the only thing I've really excelled at is creating error codes. Here is what I have: $categories = get_categories(array('child_of' => '8')); foreach ($categories as $cat) { echo $cat->name; };

• PHP: $_POST array to XML file and display results.

  - by user633264

  I'm creating a "Madlibs" page where visitors can create funny story things online. The original files are in XML format with the blanks enclosed in XML tags (Such as blablabla <PluralNoun></PluralNoun> blablabla <Verb></Verb> ). The form data is created using XSL and the results are saved using a $_POST array. How do I post the $_POST array between the matching XML tags and then display the result to the page? I'm sure it uses a "foreach" statement, but I'm just not familiar enough with PHP to figure out what functions to use. Any help would be great. Thanks, E

• Java - problems iterating through an ArrayList

  - by cc0

  Ok so I have an ArrayList (arrBok), which is full of book objects (the code is in Norwegian, so pay no attention to that please). I want to make a public method which iterates through all the objects in the arraylist. When I execute the code, it just seems to run in an infinite loop, not producing any return values. Here is the relevant (I hope, because there are a couple of other classes involved) part of the code; public String listAll() { itr = arrBok.iterator(); while (itr.hasNext()) { i++; } return "lol"; } This code does nothing useful, but I just want to see if it can iterate through it successfully. What I have tried so far; Tested if the bokArr (arraylist) is empty, which it's not. It has 4 objects inside of it. Return the toString() method of the itr, with the following result; java.util.AbstractList$Itr@173a10f // <-- not sure if this would be relevant to anything return itr.next().toString(); <-- // which seems to return the first object in the array, does that make sense?

• How to simplify my code... 2D NSArray in Objective C...?

  self.myArray = [NSArray arrayWithObjects: [NSArray arrayWithObjects: [self d], [self generateMySecretObject],nil], [NSArray arrayWithObjects: [self generateMySecretObject], [self generateMySecretObject],nil],nil]; for (int k=0; k<[self.myArray count]; k++) { for(int s = 0; s<[[self.myArray objectAtIndex:k] count]; s++){ [[[self.myArray objectAtIndex:k] objectAtIndex:s] setAttribute:[self generateSecertAttribute]]; } } As you can see this is a simple 2*2 array, but it takes me lots of code to assign the NSArray in very first place, because I found that the NSArray can't assign the size at very beginning. Also, I want to set attribute one by one. I can't think of if my array change to 10*10. How long it could be. So, I hope you guys can give me some suggestions on shorten the code, and more readable. thz

  I just saw the following code among the successful submissions at codechef. http://www.codechef.com/viewplaintext/1595846 I used to think that float max(int n,int arr[n][n]) {....} is not allowed in C++ (as 'n' is a variable). My CodeBlocks (on windows) with MinGW [gcc 4.4] gives compile time error. that "error: array bound is not an integer constant. Then how can be such a solution be accepted by CodeChef's judge. Is there any special flag that allows us to do that in C++??? EDIT: A link showing status as AC (accepted) : http://www.codechef.com/viewsolution/1595846
