C++ :: Multidimensional Array - Moving Whole Int Array Row As A Single Unit?

Feb 27, 2013

I have a multidimensional array that runs parallel with a string array

Lincoln 120 300 400
Parks 100 500 250
Shakespeare 0 30 50
Ghandi 250 100 40
Ashe 300 50 175
Rodriguez 87 118 320
Curie 284 0 112

I need to sort this and I know how to do it. But I need to sort it again with the highest value in the first row and keep all information in that row paired with the name . So

Lincoln 120 300 400
Parks 100 500 250

Parks 100 500 250
Lincoln 120 300 400

I need so swap this whole rows. I'm using dynamic array. So my question is Do I have to do a bunch of temps to move them? Or is there a way to move the whole int array row as a single unit?

C++ :: Tic Tac Toe Game With Multidimensional Array

Jan 13, 2015

Problems :

1) Is there any way so that i can use "X" and "O" char instead of 9 and 0 int.?? I also tried to use enum but was only able to print out -1 for 'X' and 0 for 'O'...

2) if player - 1 choose field 2 . and player - 2 chooses field 2 .. how can i show error and ask for another input ?

3) is there any short coding trick for int check_result(); ?

Code:
#include <iostream>
#include <string>
#include <cstdlib>
using namespace std;

Jul 31, 2014

What is the correct method of declaring pointer to multidimensional array

Code:
int array[3][4];
int *p = array;

The above code works but it shows warning. Is it an invalid way of using the pointer? the array is an address then why am i getting warning?

C++ :: Passing A Multidimensional Array

Sep 25, 2013

I'm trying to pass a two-dimensional array to a function. The function is defined as: long foobar(char foo[][CONST]); I have to create that array dynamically. Currently I do that this way: char* bar = new char[count * CONST];

But when I'm trying to pass the array I get a type conversion error. I tried a lot of different ways to pass the pointer and/or to allocate the memory, but apparently I didn't find the right way or combination of definition, allocation, casting and calling.I cannot change the definition of the function, which (IMHO) is pretty stupid. :(

C++ :: Dynamically Allocating Multidimensional Array?

Nov 24, 2013

Working on this one from the Jumping into c++ book. The book asks that I create a multidimensional array at run time based on user input and fill it with a multiplication table

My code compiles fine but throws an uninitiated error for p when I try and run it.

Code:
void multiDimentionalMultiplication(int x, int y, int z){
int ***p;
**p = new int[x];
std::cout << "Allocating array.

C :: Using A Pointer To Parse Multidimensional Array

Feb 27, 2015

I have a 3-dimensional matrix(3,3,3) and want to write it to a file. I have the code for parsing it in a compatible for matlab format. But at this point i want to use a pointer to do the same thing.

Code:

#include <stdio.h>
#include <stdlib.h>
int main() {
const int dimx = 3, dimy = 3;
int i, j;
unsigned char a[3][3][3] = {

[Code]...

If it is a 1-dimensional array i can understand the logic.

Code:

int val[7] = { 11, 22, 33, 44, 55, 66, 77 } ;
int *p;
p = val[0];
for ( int i = 0 ; i <= 6 ; i++ )

C++ :: Initializing Multidimensional String Array?

Nov 15, 2014

In one of my programs I have a 3x3 array of string that I use to display the outcome to rock, paper, scissors, and another 1x3 used for a number guessing game. I have the arrays declared in the header file as follows:

//Games.h
std::string rpsOutcome[3][3];
std::string hiLoOutcome[3];

and then initialized them in the cpp file:

//Games.cpp
string rpsOutcome[3][3] {
//row 1
{ "Both of you picked rock, you tied. Try again",
"You picked rock, the computer picked paper, you lose",

[code]....

From what I've read, Im pretty sure thats how your supposed to initialize multidimensional arrays (using the nested braces), but when I build the project, I get the following error:

C++ :: Output Multidimensional Array Using For Loops

Feb 12, 2013

In the code that I am working on I am generating random numbers and assigning them a 2d array. But when I output the array in a separate nest of for loops the values are incorrect, but if I output the array in the same nest of for loops the values are correct

int spot[4][4];
int range[] = {1,16,31,46,61}, held[4];
void Generate() {
for (int y =0; y<=4; y++) {
for ( int x =0; x<=4; x++) {
spot[x][y] = (range[x] + rand() % 15);

C++ :: Parsing Multidimensional Vector Into Array

Nov 30, 2013

For a rather complex and strange reason that I won't explain right now, I need to have this going on in my program.

class FVF{
private:
vector<vector<float>> data; //Contains fvf data for Direct3D stuff
public:

[Code].....

The FVF allows this Model3D class to also be compatible with file handling methods I've got, but here's the problem. D3D buffers require an array to feed them the information, and I know that for a single dimension of vector I can use vec.data(), how to do this for multiple dimensions.

I think the best Idea I've got so far is to set the vector within the Model3D class as a pointer, then I can union it with a float pointer... Once I can guarantee the information is correct and complete, manually transfer the contents of the vectors into the float pointer.. (The union is to reduce memory needed instead of having the data repeated in vectors and arrays)

how I could just pass these as arrays?

C++ :: Loop Unrolling Multidimensional Array?

Nov 16, 2013

I am trying to unroll the inner i and j loops within this multi-dimensional array which spits out a block image. Unfortunately, the image does not match the color of the original image probably because filter->get(i,j) gets altered in a way that I don't want it to.

double
applyFilter(struct Filter *filter, cs1300bmp *input, cs1300bmp *output) {
long long cycStart, cycStop;
cycStart = rdtscll();
output -> width = input -> width;
output -> height = input -> height;

C++ :: Passing Multidimensional Array To A Function

Apr 10, 2012

After passing the address of the first element (&array[0][0]) of a multidimensional integer array to a function with a "const int*" parameter, parameter seems to be pointing to the wrong values, which are not the actual elements of the passed array.

First, why does this happen ?

Second, how can I fix this without changing the parameter type into a multidimensional int array ?

C/C++ :: Print Single Linked List Backward With Functions / Classes - Error Message Regarding Header Files

Oct 11, 2014

I'm trying to print a single linked list backward with functions/classes. I have created the main file and 3 header files. But I'm getting an error on one of the header files, linkedListIterator after adding #include "linkedListType.h". It says that "linkedLlistType.h" is calling itself. And when I try to run it, I get an error of "too many header files." I have tried changing the headers many times, but nothing seems to work.

.cpp file:

/*(Printing a single linked list backward) Include the functions reversePrint and recursiveReversePrint, as discussed in this chapter, in the class linkedListType. Also, write a program function to print a (single) linked list backward. (Use either the class unorderedLinkedList or the class orderedLinkedList to test your function.)*/

C# :: Parsing Save File Into Multidimensional Array

Mar 26, 2015

I have this file that I would like to read into a multidimenstional array in c#: file. If I take the first set of lines as a first example, I would like the print_r to look something like this:

Array (
[SiiNunit] => Array (
[0] => Array (
[nameless.2BB8.4FB8] => Array
[0] => Array (
[bank] = _nameless.2917.43B0
[player] = _nameless.2813.6928
[companies] = 312

C/C++ :: Read Strings From File And Place Into Multidimensional Array

Mar 1, 2014

I am having problems figuring out how to place a list of strings from a text file into a multidimensional array that is something like words[NUM_WORDS][MAX_LEN]. I already run through the file once and count the number of words in it. I have tried a number of loops using fscanf and fgets, but I'm not sure if I am using them right -- this is my first time using them. The text file is a list of words in a dictionary, so the wordCount is about 45340.

Here is my code:

#include <stdio.h>
#include <string.h>
#define MAX_LEN 46
int main(){
int wordCount = 0;
FILE *inputFile, *outputFile;

[Code] ....

Like I said, the wordCount portion works. I added the printf statements at the end to see if anything was being saved, but it just prints two new blank lines. New to file reading and writing.

C/C++ :: Read BMP Image Data Into Multidimensional Array Of Structures

Apr 8, 2014

I am trying to read the information from a .bmp file into my program while dynamically allocating memory for all of it. So I defined the structures for the headers and for a pixel, and then I have to read each pixel into a multi-dimensional array of pixels. I am completely new to structures, and definitely new to pointers combined with structures. I will have to use a filter with the information later, but right now I just want to read everything in correctly. The array of pixels will be two-dimensional -- the width by the height of the image, I guess.

Here's my code:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int main(int argc, char *argv[]) {
FILE *inFile, *outFile;
typedef struct

Visual C++ :: Multidimensional Array Having 3 Rows And 8 Columns - Bubble And Selection Sort

Feb 19, 2014

You will write a program that uses a multidimensional array having 3 rows and 8 columns and sorts each of the rows using both a bubble sort and a selection sort.

You must declare the array inside of main. You will have a for loop containing the calls to bubbleSort and selectionSort. You need to pass into function bubbleSort and selectionSort the following: 1) each column of the multidimensional array, 2) the size of the column, and 3) a particular row number of the multidimensional array to be used for printing out the "pass" shown on the following pages.

I keep getting an error that the identifier for bubbleSort and selectionSort is not found. (Error C3861)

Also, I feel like I'm missing something in int main() to get it to sort properly.

Code:
# include <iostream>
using namespace std;
int main() {
const int SIZE1 = 3;
const int SIZE2 = 8;
int arr [SIZE1][SIZE2] = { { 105, 102, 107, 103, 106, 100, 104, 101 },
