Hello! I'm working on a project that's going to print out to a bitmap(more specifically a RAW, but that's not important to the question), but I'm working in a 2-D array in-program. I want to be able to draw a line from point (a,b) to point (x,y) for any arbitrary values of a,b,x, and y. I don't need anything fancy like anti-aliasing; a...
I've got a Car class and a Track class. The Car class constructor takes a road parameter which is supposed to be a 32x32 boolean array. Then I've got a Track class which creates a Car class and is supposed to pass the 32x32 array to it's constructor. Note that I've simplified the code somewhat by removing irrelevant bits and pieces. ...
I am struggling through objects in perl, and am trying to create a 2d array and store it in a hash field of my object. I understand that to create a 2d array I need an array of references to arrays, but when I try to do it I get this error: Type of arg 1 to push must be array (not hash element) The constructor works fine, and set_seqs wo...
I've got 2 2D arrays, one int and one String, and I want them to appear one next to the other since they have the same number of rows. Is there a way to do this? I've thought about concatenating but that requires that they be the same type of array, so in that case, is there a way I could make my int array a String array? ...
So I'm starting my magic square hw, where I ask the user to enter a odd integer, and it will create a magic square off that. I have to use pointers and arrays as that is all I have learned so far. Not asking how to do the magic square, but what is causing a segmentation fault, im probably not doing pointers to 2d arrays correctly #inclu...
I read that Python does not actually support 2D arrays but rather an array of an array. I understand the array of an array thing but what does it mean by supporting 2D arrays? In C a 2D array is simply converted to a 1D array by doing some fancy math (Seen here). Are there languages that implement actual 2D arrays? Thanks for the hel...
here is the code I have written in java I think it is right. I am just not sure what to set result to? I want to return the element associated with the specific row column public int getElement(int row,int col){ int result = 0; if(((row>=1) && (row <=rowArray.length))&&((col>=1) && (col <=colArray.length))){ result = ??...

Hi I'm having some problem with 2D dynamic array. int main() { double **M; int M_dimension; int i; M_dimension = 10; M = new double *[M_dimension]; for (i=0;i<M_dimension;i++) { M[i] = new double[M_dimension]; } M[0][0] = 1.0; ... } Program works but I'd like to initialize 2D array using such a fun...
I have a 2D array which I want to send to a php page with $.ajax. This is the code which creates the array: for (var i = 0; i<rowlen; i++) { if (breakcheck) { break; } for (var j = 0; j<=columnlen; j++) { ...
I have already written a program that sorts a 2D array in increasing values. Here is my input and output. Input: Array2D[0][0] = 99 Array2D[0][1] = 10 Array2D[0][2] = 97 Array2D[0][3] = 10 Array2D[0][4] = 14 Array2D[1][0] = 73 Array2D[1][1] = 53 Array2D[1][2] = 81 Array2D[1][3] = 22 Array2D[1][4] = 88 Output: Array2D[0][0]...

I am writing a C program which has to use a 2D array to store previously processed data for later using. The size of this 2D array 33x33; matrix[33][33]. I define it as a global parameter, so it will be initialized for only one time. Dose this definition cost a lot of time when program is running? Because I found my program turn to be ...
If I have a 2d array such as smallArray = [[1,0],[0,1]] and I have a larger 2d array such as largeArray = [[0,0,0,0],[0,0,0,0],[0,0,0,0],[0,0,0,0]] What would be the most efficient way to "tile" the smaller array in the bigger one so that the bigger array would end up looking like largeArray = [[1,0,1,0],[0,1,0,1],[1,0,1,0],[0,1,0...
This is in C. I have two 2D arrays, ArrayA and ArrayB, that sample the same space. B samples a different attribute than ArrayA less frequently than ArrayA, so it is smaller than A. Just to try to define some variables: ArrayA: SizeAX by SizeAY, indexed by indexA for a position posAX, posAY ArrayB: SizeBX by SizeAY, indexed by indexB...
