Design and implement the class myArray that solves the array index out of bound problem, and also allows the user to begin the array index starting at any integer, positive or negative. Every object of type myArray is an array of type int. During execution, when accessing an array component, if the index is out of bounds, the program must terminate with an appropriate error message. Consider the following statements:
myArray<int> list(5); // Line 1
myArray<int> myList(2,13); //Line 2
myArray<int> yourList(-5,9); // Line 3
The statement in Line 1 declares list to be an array of 5 components, the component type is int, and the componentst are : list[0], list[1]…list[4]; the statement in Line 2 declares mylist to be an array of 11 components, the component type is int, and the components are: mylist[2],…mylist[12].
This is what I have so far:
#ifndef H_myArray
#define H_myArray
#include <iostream>
using namespace std;
template <class myArray>
class myArray
{
public:
private:
return 0;
};
#endif
I'm getting "Index was outside the bounds of the array." computerInput.pher[i, 0] = computerInput.availperi[a]; on line 198 but I'm not sure what I need to do in order to correct it. My array seems fine to me and I do see that "i" is showing 0 when debugging and won't change. Either I'm missing something or wrote my array wrong.

Above code is compiling as I expect it to be.
Problem is when I run it, it prompts me the following message:
Out-of-bounds access (ARRAY_VS_SINGLETON). Passing "c" to function "operator +(HSTString const &, char const *)" which uses it as an array. This might corrupt or misinterpret adjacent memory locations.
So I'm making setTimeout and setInterval functions.
I have this remember function (that is part of Timing class) which takes a function pointer and a void pointer, which are remembered in that object.
Another (timing) function of that object is called in every loop of the program and when specific time passes that function calls the remembered function whit the remembered void pointer as argument.
The problem is that the functions that need to be called require unknown multiple parameters, so what I need to do is make a new class that will store the needed arguments. I make the function that needs to be called and that storage object and pass pointers to them to my remember function, when the remembered function is called it stores the data from storage object in new variables and dose it's thing.

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?
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(); ?

#include <iostream>

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?
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. :(
I have put aside C++ for a while. And I am back to it.
I forgot how to return a 2 dimensional arrays from a method?

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:

int ***p;
**p = new int[x];
std::cout << "Allocating array.

I have initialized a multidimensional array eg char fruit[5][10]...Then I would need to read in 3 words with spaces in between from user and store in fruit[5][10] e.g "pear apple orange"
The thing is that after typing orange, when I press Enter it still prompts me to enter more characters. How can I end the scanning of characters after orange ?
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] = {

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++ )

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);

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?
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;

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 ?
I am currently trying to write a program, which i able to print a multidimensional array using classes. My problem is, it prints random values, and not the value from the user input.

From the example given below, I would like to Generate a matrix who stores a generated array for each iteration. I have an understanding of inputting single elements to a matrix but how can I input an array to a matrix. let's say I would like to input and array of 4 elements that should be stored as a single row of the generated matrix and do this for an infinite while{true} loop.

How can I Passe some part of multi-Dimensional Array to a Function; for example only two dimension of three dimension of a an array with 3 dimension. This is because my function is defined for working with 2 dimension arrays.

View 3 Replies View RelatedI 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.
