Whats The Most Efficient Way To Instantiate Worker Variables
Should I instantiate my worker variables inside or outside my for loop E.g. a) bool b = default(bool); for (int i = 0; i < MyCollection.Length; i++) { b = false; foreach(object myObject in myObjectCollection) { if (object.Property == MyCollection[i].Property) { b = true; break; } } if (b) {...
Replace string characters from array.
I have a string (of undertermined length) that I want to copy a lot of times replacing one character at a time from an array (of undertermined length) of characters. So say I have this string: 'aa' And this array: ['a', 'b', 'c', 'd'] after some magic for-looping stuff there would be an array like: ['aa', 'ab', 'ac', 'ad', 'ba', 'bb'...
Is there a hidden iteration counter in this for loop?
If you have a for loop such as: For Each s As String In stringList ..do stuff.. Next is there some sort of (hidden) iterator or do I have to add an external integer to keep count: Dim i As Integer For Each s As String In stringList ..do stuff.. i += 1 Next ...
Is there any way to do n-level nested loops in Java?
In other words, can I do something like for() { for { for { } } } Except N times? In other words, when the method creating the loops is called, it is given some parameter N, and the method would then create N of these loops nested one in another? Of course, the idea is that there should be an "easy" or "the usua...

In XSLT how do I access elements from the outer loop from within nested loops?

Don't monkey with the loop index
One of Steve McConnell's checklist items (pdf) is that you should not monkey with the loop index. This makes intuitive sense and is a practice I've always followed except maybe as I learned how to program back in the day. In a recent code review I found this awkward loop and immediately flagged it as suspect. for ( int i=0 ...
Is there a way to access an iteration-counter in Java's for-each loop?
Is there a way in Java's for-each loop for(String s : stringArray) { doSomethingWith(s); } to find out how often the loop has already been processed? Aside from using using the old and well-known for(int i=0;i<boundary;i++)-loop, is the construct int i = 0; for(String s : stringArray) { doSomethingWith(s); i++; } the only wa...
Replace Nested For Loops... or not
I have a script that loops through a series of four (or less) characters strings. For example: aaaa aaab aaac aaad If have been able to implement it with nested for loops like so: chars = string.digits + string.uppercase + string.lowercase for a in chars: print '%s' % a for b in chars: print '%s%s' % (a, b) ...

How to calculate the number of operations that occur during the execution of a for loop?

Does the termination condition of a 'for loop' refresh in VC++ 6?
for (int i = 0 ; i < stlVector.size() ; i++) { if (i == 10) { stlVector.erase(stlVector.begin() + 5 ) } } Does the termination condition part "stlVector.size()" take "stlVector.erase(...)" into consideration? In other word does stlVector.size() refresh for every loop iteration? I can't test it right now, so i post...
