Which one of these for loops will iterate through each character in a std::string faster?

Code:

for (unsigned i = 0u; i < str.length(); ++i)

Code:

for (unsigned i = 0u, end = str.length(); i < end; ++i)

Hello,
I've put together the following javascript that can be dragged and dropped to the favorites/bookmarks bar in Chrome (or any browser) and then when you click on it, it opens the links in the variable object:

Code:

javascript:(function(){ 
var obj={"link1":"http://google.com", "link2":"http://yahoo.com"};
for(key in obj){
var val=obj[key];
window.open(decodeURIComponent(val));

This is a formula I am writing in Crystal Reports and vb is the closest thing to it so hopefully someone can figure this out.

I am dealing with a long string that looks like 0.0055;0;0;0;0. It looks like an array but doesn;t act like on. For example, I only need the first value but if I ask for myArray[1], I get "0", myArray[2] yields ".", etc. So I created this for loop to get what I want:

Code:

Hi all,

I have a trivial stored procedure that needs to reorder data by changing displayorder field value.

Code:

CREATE PROCEDURE SVC.REORDER_DIVISIONS_ALPHA
(
 IN code VARCHAR(12),
 IN year INTEGER
)
LANGUAGE SQL P1:
BEGIN
	DECLARE counter INTEGER;
	SET counter = 1;
	FOR divisions AS 
	   SELECT ID FROM SVC.DIVISIONS SV 
           WHERE   SV.LYEAR = year AND CODE

Hello, I am using a for loop to iterate through an array and need to assign each iteration to a new variable, such as

Code:

arr = ['bread', 'milk', 'cheese']
for i in arr:
    print i

but instead of printing i, I want the for lopp to assign each iteration to a unique variable, so that when the for loop completes

Code:

var1 = 'bread' 
var2 = 'milk'
var3 = 'cheese'

Hey ! I am a Semi-pro/Amateur kind of Java Programmer. A student. I use BlueJ to write Java Programs. I was writing a Java Program to display the prime factors of a number entered. However the compiler was constantly showing error of missing return statement. Why ? and can u tell me how to cure it ?

Code:

public class Prime_Factorizer
{
public static void main(int a)
{
final int l = a ;
System.out.println("Prime

Please someone explain me

Code:

#!/bin/bash

ARRAY=("example program" "for test only" "Lets try");

ELEMENTS=${#ARRAY[@]};

echo $ELEMENTS;

for((i=0;i<$ELEMENTS;i++));do

done

I know what i will get by executing this. got this from a website.
But I dont understand...

I'm trying to create an "For Each...Next" setup where I can go through every row on a table. I need to check a specific column, and depending on that value I have a count running. It seems to work but it keeps raising a "Error 424: Object required" box.

Any Ideas? Btw this code is being executed on a form that displays statistics.

Code:

For Each dr In Tables.FCG10.rows
    Select Case dr.[field]

Develop a program which computes the current value of the vector {x}
based on the following forward iteration:

{x}(n+1) = [K] {x}(n)+ {z}, n = 0,1,2,3,4.

In other words, the next vector {x} is equal to the product of [K] and
the current vector {x} + constant vector {z}.

Perform the matrix multiplication by using the function:

void matrix_mult(dou ble a[3][3], double *b, double *c, int...

I have the following code, which is going through a FOR loop to run an INSERT statement with a nested SELECT statement. The issue is that I am trying to use the interator in the SQL statement, but the number never changes, even though the process is running through the proper number of times. What am I missing? Why is the number not appearing to be changing?

Code:

 Sub SetLEAs()
    Dim MyCnt As Integer
    Dim i As Integer
