When I use new[] to create an array of my classes: int count = 10; A *arr = new A[count]; I see that it calls a default constructor of A count times. As a result arr has count initialized objects of type A. But if I use the same thing to construct an int array: int *arr2 = new int[count]; it is not initialized. All values are somet...
What I'm trying to accomplish with this code is to output the array alphabet as a series of list items into an existing unordered list in the actual markup. I've got the array into list items, but I can't figure out how to tell it to append itself to an existing unordered list <ul id="itemList"></ul>. var itemsExist = true; var indexNu...

Hello! Very simple question - how might I iterate through a NSMutableArray and do things for each item? Much like the for loop in other langs: foreach(array){ dosomething(); } Thanks! Christian Stewart ...
Say I have a bash array (e.g. the array of all parameters) and want to delete all parameters matching a certain pattern or alternatively copy all remaining elements to a new array. Alternatively, the other way round, keep elements matching a pattern. An example for illustration: x=(preffoo bar foo prefbaz baz prefbar) and I want to d...
I want to be able to know the level of an array as it is being built. The code loops through a bunch of directories to create a massive multi-dimensional array. As the array is being created, I want to know how deep in the array I am. 1 2 3 4 --------------------- Root A A2 A3 A4 ...
I have an nested array that's a mix of words and numbers. It looks like this conceptually. I need to process only numbered indexes such as 15 and 28. I guess this means that I can't use a foreach loop (or is there a way I could). How would you do this? myarray = ( someindex = ( field1 = field2 = ); 15 = ( fie...
I have an array that I made that consists of first names. I have a search function that searches through the elements of the array and it works fine. However, for multiple elements of an array, I cannot find out how to print how many results were returned. For example, if "John" in my example is found, which it is, I do not know how to s...
I have a a handful of dynamically generated inputs. Some have IDs, some do not.I also have an array of IDs. I need to loop through the array of IDs and input the next available ID into the next input without a value. I have tried $.each(event_array, function(intIndex, objValue){ $('.event-data').find('.event-id').each(function(i){ ...

I want to extract each item on each page and assign it it's corresponding category number i.e. category-1_ITEM - CAT-1 ...
What is an elegant way to take a javascript array, order by the frequency of the values, and then filter for uniques? So, ["apples", "oranges", "oranges", "oranges", "bananas", "bananas", "oranges"] becomes ["oranges, "bananas", "apples"] ...
C++: Using and returning character arrays from functions, return type or reference? I'm trying to create a null terminated string outside of a function, then run a function which will assign some data to it. For example, char abc [80] is created in main. input() is then run, which will return user input to abc. I figure the two obviou...
More of a syntax curiosity than a problem to solve... I have two arrays of equal length, and want to iterate over them both at once - for example, to output both their values at a certain index. @budget = [ 100, 150, 25, 105 ] @actual = [ 120, 100, 50, 100 ] I know that I can use each_index and index into the arrays like so: @budget...
Is there an equivalent for ruby's array[n..m] in Javascript ? For example: >> a = ['a','b','c','d','e','f','g'] >> a[0..2] => ['a','b','c'] Thanks ...
I have a function similar to this: void foo(obj ary[], int arysize) { for (int i = 0; i < arysize; i++) ary[i] = obj(i, "abc"); } And I call it like this: obj array[5]; foo(array, 5); It's supposed to populate the array with my objects. However, when it returns, the objects are garbage. It works with value types like i...
