问题 I'm iterating through the GridView rows and cells to get the values and store them in a 2D array . This is my code: for (int i = 0; i < GridView2.Rows.Count; i++) { for (int j = 0; j < (GridView2.Rows[i].Cells.Count - 3); j++) { // using the labels of the template fields..... Label values = (Label)GridView2.Rows[i].Cells[j].FindControl("Label" + j); GridValues[i,j] = values.Text; // gridvalues is my 2d array. } } What I need now is to make the same values I got from the above loop to be added

问题 The four programs below input a 2 D array and then print it out. The first one prints out garbage values and also gives out a few warnings (Which I did not understand). The 2nd one works correctly , also it kinda makes sense as I believed that a 2 D array is stored linearly in memory. The 3rd one works correctly , but I have no idea why it works. The 4th one works as well. So it would be of great help if someone could explain how each of the methods work , cheers I'm afraid my understanding

问题 I have two arrays which I want to join together. I want to preserve the indexes. First Array (start times) array(2) { [0]=> array(2) { ["ID"]=> string(2) "15" ["start_time"]=> string(19) "2012-06-24 08:00:00" } [1]=> array(2) { ["ID"]=> string(2) "28" ["start_time"]=> string(19) "2012-07-26 18:00:00" } } Second Array (end times) array(2) { [0]=> array(2) { ["ID"]=> string(2) "15" ["end_time"]=> string(19) "2012-06-24 17:00:59" } [1]=> array(2) { ["ID"]=> string(2) "28" ["end_time"]=> string

问题 In using Dev C++, I a m trying to insert a smaller 2D array object into a larger 2D array object. While attempting to achieve that, I came into compilers errors which I do not know how to solve. I attempt to insert the smaller Object by making it returning the array's name. Then I attempt to change the values inside the large array with the values of the smaller array. There two line of code that I have problems with: int result = smallerArray.extractPiece(); largerArray.extractArray(result);

问题 I have a list of line items to an order, but the feed we receive divides multiple quantities of a single item into separate line items. I need to combine and/or certain elements if the sku is the same and only return one line item for each sku. I need to sum tax, shipping and shipping tax for each item. [Sku]=> 47069 [QTY]=> 1 [Price]=> 5.9900 [Tax]=> 0.4200 [Shipping]=> 2.5800 [ShippingTax]=> 0.1800 [Sku]=> 241573 [QTY]=> 1 [Price]=> 6.4900 [Tax]=> 0.4700 [Shipping]=> 0.9300 [ShippingTax]=>

问题 This is my array i want to check one index value to remain other index value and if product_id value same then sum of total_qty. i am stuck in this situation.i need help.Thank you in advance. Array ( [0] => Array ( [iProduct_id] => 1 [fTotal_qty] => 200 ) [1] => Array ( [iProduct_id] => 2 [fTotal_qty] => 400 ) [2] => Array ( [iProduct_id] => 6 [fTotal_qty] => 500 ) [3] => Array ( [iProduct_id] => 4 [fTotal_qty] => 300 ) [4] => Array ( [iProduct_id] => 5 [fTotal_qty] => 200 ) [5] => Array (

问题 The method below loops through a given int[] , storing both the frequencies of the numbers found in the array along with each different appearing number into a HashMap . After looping, the HashMap would look something like this (num=frequency): {0=4, 656=1, 1=1, 2=2, 3=2, 4=3, 8=1, 56=1, 75=1, 12=3, 13=1, 61=1} Following this, the method creates a char[][] , representing designated x & y coords for the size and frequency of each integer. The x axis represents the size of the number, and the y

问题 I have the following data: Array ( [0] => Array ( [filename] => def [filesize] => 4096 [filemtime] => 1264683091 [is_dir] => 1 [is_file] => ) [1] => Array ( [filename] => abc [filesize] => 4096 [filemtime] => 1264683091 [is_dir] => 1 [is_file] => ) [2] => Array ( [filename] => rabbit [filesize] => 4096 [filemtime] => 1264683060 [is_dir] => 0 [is_file] => ) [3] => Array ( [filename] => owl [filesize] => 4096 [filemtime] => 1264683022 [is_dir] => 0 [is_file] => ) ) and I would like to sort it

问题 In this post, I'm using the term slice to refer to a subarray B_i of an n -dimensional array A such that size(B_i, d) is 1, for some dimension d . A consists of size(A, d) such slices, concatenated along dimension d . For example, if ndims(A) is 6 and d is 3, then the expressions of the form A(:, :, i, :, :, :) for i in 1:size(A, d) represent all the slices (along dimension d ) that make up A . The problem with an expression like A(:, :, i, :, :, :) is that it cannot be generalized
