问题 I have a 2d array (a chess board, but this is irrelevant to the problem) and I want to fill it using a function. The one I've written works fine, but after launching the program the console crashes. Any idea where the problem is? Thank you. #include <stdio.h> #include <stdlib.h> void fill(int board[8][8]); int main() { int board[8][8]; fill(board); return 0; } void fill(int board[8][8]) { int a,b; for (a = 1; a <= 8; a++) { for (b = 1; b<= 8; b++) { if ((a==1) || (a==8)) board[a][b] = 7; if (

问题 Given a 5 x 5 Grid comprising of tiles numbered from 1 to 25 and a set of 5 start-end point pairs. For each pair,find a path from the start point to the end point. The paths should meet the below conditions: a) Only Horizontal and Vertical moves allowed. b) No two paths should overlap. c) Paths should cover the entire grid Input consist of 5 lines. Each line contains two space-separated integers,Starting and Ending point. Output: Print 5 lines. Each line consisting of space-separated integers

问题 I'm writing a code which must return a long array from C to java using JNI. But the method (*env)->FindClass returns NULL whatever I tried. Here is my code : // Returns a 2D long array from C to Java JNIEXPORT jobjectArray JNICALL Java_awax_tools_AcquisitionWrapper_startAcquisition (JNIEnv *env, jobject obj) { // (...) Acquisition code // The 2D long array to return long** primitive2DArray = data; // Get the long array class jclass longArrayClass = (*env)->FindClass(env, "[java/lang/Long"); /

问题 I'm trying to write a program for an assignment. The requirements are to create Pascal's Triangle recursively and then print a given line. However, after compiling my program, I get several ArrayIndexOutOfBoundsExceptions. Here is the stack trace: java.lang.ArrayIndexOutOfBoundsException: 10 at pasTriangle.populateT(pasTriangle.java:79) at pasTriangle.populateT(pasTriangle.java:86) at pasTriangle.populateT(pasTriangle.java:86) at pasTriangle.populateT(pasTriangle.java:86) at pasTriangle

问题 Saw similiar (not the same, though) quesion yesterday and I realized I do not know it either. Lets say there we have a 2 dimensional " int[,] " array with elements like this: 1,2,3,4,5 5,4,3,2,1 And I want to reverse elements order in both dimensions rows: 5,4,3,2,1 1,2,3,4,5 Or just in one: 5,4,3,2,1 5,4,3,2,1 Only way I could think of is doing that manually in for statement. Any other idea? 回答1: You can try to use Array.Reverse for each line of array. Update: If you can use array of arrays

问题 $objPHPExcel->getActiveSheet()->fromArray($dataArray,null,"A2") I've the above line of code. The problem is, I am not good at iterating and I want all the cell values to be set as STRING so as to avoid automated modifications of texts leading zeros. P.S. In Addition, code for setting as STRING for selective columns will be appreciated. Thanks! 回答1: When you set cell values individually, you have the option of setting the datatype explicitly, but when you use the fromArray() method, you don't

问题 I am trying to create json with php from two mysql tables: - Category(unique) - Subcategories or Rights(multiple in same category) But I can't list multiple subcategories under one category. Instead, for every subcategory new set of results is made that contains category data also. This is php code: $sql = "SELECT a.id as rid,a.name as rname,a.img as rimg,a.price,b.id as cid,b.name as cname FROM rights a INNER JOIN categories b ON a.category=b.id"; $result = $mysqli->query($sql); if ($result-

问题 If my array is A(i,j) can I use Array.Clear to zero all of the elements for i=2, for example. It does not work as I expected. 回答1: Take a look at this example. If I want to initialize all the elements for the second row (index = 1) I specify the starting position in the array ordered by row ascending, column ascending and the number of records to clear as the number of columns in your array. Dim arr(,) As Integer = {{1, 2, 3}, {4, 5, 6}} Array.Clear(arr, 1 * 3, 3) Clearing the entire array
