If there were such a thing I would imagine the syntax to be something along the lines of while(Integer item : group<Integer>; item > 5) { //do something } Just wondering if there was something like this or a way to imitate this? ...
How do you Make A Repeat-Until Loop in C++? As opposed to a standard While or For loop. I need to check the condition at the end of each iteration, rather than at the beginning. ...
Hi guys, I'm making a demo workflow that is a while loop with a sequence of a single delay, that delays for 5 seconds. I've made the while loop use a Declarative Rule Condition where I set it to 1 == 1. All fine, but the loop only ever loops once, and then my workflow sais "Error Occurred". Any idea what's going on? For the record, th...
In this code sample, is there any way to continue on the outer loop from the catch block? while { // outer loop while { // inner loop try { throw; } catch { // how do I continue on the outer loop from here? continue; } } } ...
I found this piece of code on Wikipedia. #include <stdio.h> int main(void) { int c; while (c = getchar(), c != EOF && c != 'x') { switch (c) { case '\n': case '\r': printf ("Newline\n"); break; default: printf ("%c",c); } } return 0; } I'm curious about expression ...
Assume i have the following code, there are three for loop to do something. Would it run fast if i change the most outer for loop to while loop? thanks~~ int length = 200; int test = 0; int[] input = new int[10]; for(int i = 1; i <= length; i++) { for (int j = 0; j <=length - i; j++) { for (int k = 0; k < length - 1...
Hi! Im sure there is a better way to do this, but I am quite the newbie so I did it the only way I could figure it out. The thing is, I have a script that updates a textfile with the newest posts from an RSS feed (I got some help from you guys to figure it out). But I want this script to be automated, so I made this: import time import...
Here's what I got- $awards_sql_1 = mysql_query('SELECT * FROM categories WHERE section_id = 1') or die(mysql_error()); $awards_rows_1 = mysql_num_rows($awards_sql_1); $awards_sql_2 = mysql_query('SELECT * FROM categories WHERE section_id = 2') or die(mysql_error()); $awards_sql_3 = mysql_query('SELECT * FROM categories WHERE section...
Here's what I've got so far- $awards_sql_1 = mysql_query('SELECT * FROM categories WHERE section_id = 1') or die(mysql_error()); $awards_sql_2 = mysql_query('SELECT * FROM categories WHERE section_id = 2') or die(mysql_error()); $awards_sql_3 = mysql_query('SELECT * FROM categories WHERE section_id = 3') or die(mysql_error()); $awards_s...
Okay, so I followed the advice on this question: http://stackoverflow.com/questions/1214176/stumped-in-the-middle-of-a-php-loop But now, I'm having even more problems than before. Here's what I have so far: $sql = "SELECT section_name, category_name, result_level, url, winner FROM 2009_RKR_bestof INNER JOIN categories ON 2009_RKR_best...
I'm creating a tree-structure of categories with parentid's which can be called from children in such a way: ID | Name | ParentID 1 1 0 2 2 1 3 3 2 4 4 1 Resulting in this: 1 = 1 2 = 1 -> 2 3 = 1 -> 2 -> 3 4 = 1 -> 4 which means 3 is a child of 2, which is a child of 1. when trying to get this idea ...
Realizing that loops are usually not ideal in R, sometimes they are necessary. When writing large loops, doesn't for (i in 1:large_number) waste memory, since a vector of size large_number must be created? Would this make while loops the best choice for large, necessary loops? ...
What is the maximum number of executions in a while loop in VB.net that it will allow? Meaning, it is checking for a variable to equal some value, but that value never comes? How many times will it execute the code before it quits? Is there some way to set the maximum number of executions without terminating it programmatically? Thanks ...
I have a script that uses a simple while loop to display a progress bar but it doesn't seem to be working as I expected: count = 1 maxrecords = len(international) p = ProgressBar("Blue") t = time while count < maxrecords: print 'Processing %d of %d' % (count, maxrecords) percent = float(count) / float(maxrecords) * 100 p.ren...
When looking through some code that was handled by another employee, I see a lot of code written in: do{ ... }while(false); What advantage (if any) does this provide? Here is more of a skeleton that is happening in the code: try{ do{ // Set some variables for(...) { if(...) break; // ...
I'm new to C programming, I come from a Java background. I was wondering why in the following code, in the while loop I have to type my input ten times and then all ten inputs are displayed. I'm trying to type something once and have it displayed right after. Then continue typing my other inputs. #include <stdio.h> #include <stdlib.h> ...
Sorry, I'm new to Java, so this question might be unclear. I have been recently dealing with enclosing a try and catch statement in a while loop, because I wanted to make sure that getting input was enclosed from the rest of the program. I have come across a problem where using an exclamation mark in front of a variable in the while con...
