问题 How can I pass a multidimensional array from one activity to another? 回答1: You can create a Serializable class which wraps the two-dimensional array, and pass it using Intent.putExtra(String name, Serializable value) 来源: https://stackoverflow.com/questions/4024015/passing-a-multidimensional-array-from-one-activity-to-another

Pull Specific Data From Multidimensional PHP Array

雨燕双飞 提交于 2019-12-25 15:52:31
问题 I'm trying to pull just the 'message' data from each of these arrays contained within this multidimensional array, but can't figure out how to get deep enough in the array to pull it. The page I'm using is returning the data this way, so there is no way I can edit it to be returned differently. Array ( [0] => stdClass Object ( [revision_cache] => stdClass Object ( [revision] => 14 [email] => email@email.com [changed_dirs] => Array ( ) [account_id] => 133673 [message] => Deleted unneeded help

问题 this code should create an array in main and then print it but every time I run it I just get an array of all 0s #include <stdio.h> #include <stdlib.h> void print(float **A, int w, int h){ int i, j; A = (float*) malloc(w*h*sizeof(float)); for (i=0;i<h;i++){ A[i] = (float*) malloc(w*sizeof(float)); } for (i=0; i<h; i++){ for(j=0; j<w; j++){ printf("%f ", A[i][j]); } printf("\n"); } } int main(void) { int i; int x_dimension=3; int y_dimension=2; float arr [3][2]={}; arr[0][0]=16.2; print(arr,x

convert sub-arrays with only one value to a string

问题 I have a multidimensional array, the sub-arrays consist of further values, I would like for all sub-arrays that only have one value to be converted into a string. How can I successfully scan through a multidimensional array to get the result? Below is a small section of the array as it is now. [1] => Array ( [name] => Array ( [0] => Person's name ) [organisation] => Array ( [0] => This is their organisation [1] => aka something else ) [address] => Array ( [0] => The street name [1] => The

Fastest way to copy several 2-dimensional arrays into one 1-dimensional array (in C)

点点圈 提交于 2019-12-25 12:12:54
问题 I want to copy several 2-dimensional subarrays of 3-dimensional arrays (e.g. array1[n][rows][cols], ..., array4[n][rows][cols]), which are dynamically allocated (but with fixed length), into a 1-dimensional array (e.g. array[4*rows*cols]), which is statically allocated, in C. As there will be many rows and columns (e.g. 10000 rows and 500 columns), I was wondering which of the following three possibilities will be the fastest: for(i=0;i<rows;i++){ for(j=0;j<cols;j++){ array[i*cols+j]=array1[2

Template class constructor issues - designing a container for multidim arrays

▼魔方 西西 提交于 2019-12-25 11:56:36
问题 I'm trying to create my own container for an array of any dimension for numerical computing. I would like to do this using templates so that I could overload the subscript operator [] so that it works like normal arrays and vectors e.g. access entries like a[10][10][10] etc. I am having trouble getting the constructor to work when trying to create containers to hold multidimensional arrays. Please help! #include <iostream> #include <iterator> #include <algorithm> #include <vector> using
