NEVER MIND- IT WAS MY OWN DUMB MISTAKE, CONFUSED THE VARIABLES I have the following while loop: while (((pi.getFunds() - rmiPrice) > 0) && (rmi.getInventory() > 0)) { } pi.getFunds() is a double that represents how much money a fictional object (pi) has, rmiPrice is a double that represents a price of a product (rmi) that pi wants ...
The purpose of this question is to find the best way to print data out of PHP multidimensional arrays. How can you complete the following procedure below? I have the following arrays array1['id']['title'] and array2['id']['tags'][] The arrays have been generated by the function pg_fetch_array. This allows you refer to each value ...
I'm using a While loop that loops a certain number of cycles (1-576) based on a value entered by a user. It's activated by the user clicking a "Start" button, But I would like it to be able to be canceled using, preferably, the "Escape" key. However, when the loop is going I can't get the program to recognize any keypresses. Private Su...
How can you use the following sample data either with a foreach or while -loop? I get the following sample data by running $answers = pg_fetch_all ( $result );. Sample data [0]=> array(3) { ["answer"]=> string(7) "This is the answer" ["username"]=> string(5) "roope" ["was_sent_at_time"]=> string(26) "2009-...
I've heard this quite a few times. Are JavaScript loops really faster when counting backward? If so, why? I've seen a few test suite examples showing that reversed loops are quicker, but I cant find any explanation as to why! I'm assuming it's because the loop no longer has to evaluate a property each time it checks to see if it's finis...
Looks like while( condition ) { //do stuff } is completely equivalent to for( ; condition; ) { //do stuff } Is there any reason to use the latter instead of the former? ...
I'm using a simple loop to echo back some numbers <?php $inc = 0.25; $start = 0.25; $stop = 5.00; ?> <?php while($start != ($stop + $inc)){ ?> <option><?php echo $start ?></option> <?php $start = $start + $inc; ?> <?php } ?> However 5.00 appears as 5 and 4.50 appears as 4.5 How would i get this script to display 5.00, 4.00, 3.00, 3...
I found similar questions asked here but there weren't answers to my satisfaction. So rephrasing the question again- I have a task that needs to be done on a periodic basis (say 1 minute intervals). What is advantage of using Timertask & Timer to do this as opposed to creating a new thread that has a infinite loop with sleep? Code snip...
I'm confused. I'm trying to loop though 2 files looking at the first token in every line of the first file and comparing it to the third token of every line of the second file. Here is the logical structure in the form of a nested while loop: BufferedReader reader1 = new BufferedReader(new InputStreamReader(new FileInputStream(fromFile1...

I want to have a while loop do something like the following, but is this possible in c++? If so, how does the syntax go? do { //some code while( expression to be evaluated ); // some more code } I would want the loop to be exited as soon as the while statement decides the expression is no longer true( i.e. if expression i...
Suppose I have a while loop like: $sql = mysql_query("SELECT * FROM tablename"); while($row = mysql_fetch_array($sql)){ $id = $row["id"]; $sql_2 = mysql_query("SELECT * FROM secondtable WHERE id != $id "); while($ro = mysql_fetch_array($sql_2)){ $id2 = $ro["id2"]; echo $id2; } } then if first query return 5 results i....
Quick question, again, I'm sure this is ridiculously simple but I don't see what I'm doing wrong! while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { echo "<a href=\"http://mysite.com/{$row['row1']}/{$row['row2']} \">{$row['row3']} </a>"; } This produces all my links to be stacked up one after the other. I want to order them in...
x = y // 2 # For some y > 1 while x > 1: if y % x == 0: # Remainder print(y, 'has factor', x) break # Skip else x -= 1 else: # Normal exit print(y, 'is prime') This is an example for understanding while loop in a book I'm reading, I don't quite understand why a floor division and then y % x? Can someone please...
With MSSQL, I can mix in case, if...then, and while constructs in my SQL code. Is anything similar available for SQLite? I have not seen anything on "mixing procedurally" with SQLite, anywhere. Thanks. ...
I am writing a function to do "while" to count the numbers of alphabetic and digits in a text file. I would like to seperate it to 2 functions of 2 "while". But it error after I create the first function. What's wrong of it? #include "stdafx.h" #include "stdlib.h" #include "ctype.h" void countDig (FILE* input, char num,...
I have a script which runs in a 'while' cycle. I need to determine for how long the script was running for and if it is over 10 seconds terminate it. The code I wrote returns weird decimal values (one second it might be '5.342...' and other it might be '903.322...'). Can someone tell me how can I achieve that? $timer = microtime(false);...
