C++ :: Fixing Array Index Out Of Bounds?

Dec 7, 2014

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

C# :: Getting Index Was Outside The Bounds Of The Array Error

Sep 20, 2014

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.

C :: Fixing Size Of Array As Opposed To Using A Pointer

Oct 15, 2014

If I have an array and all I have is an upper limit on how big the array can get, and if the number of elements that get added can be considerably smaller than this limit, is it always the right choice to declare a pointer and just reallocate extra memory whenever the array grows? For instance, instead of declaring int a[max] I can declare a pointer int *a and than just realloc when I add elements.

C++ :: Out Of Bounds Access (Array / Singleton)

Feb 3, 2014

#include <iostream>
int main() {
int bit = 1;
int init = 0xf ^ (1 << bit);
char* c = new char(2);
sprintf(c, "%x", init);
std::string initVal = std::string("4'h") + c;
std::cout << initVal << std::endl;
}

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.

C/C++ :: Take Values From One Array And Searches For Their Index Position In Another Array

Dec 9, 2014

My program takes the values from one array and searches for their index position in another array (linear search algorithm). This is an example of the issue im having(its not part of the actual code below)

a[]={1,2,3,4,5,6}
Arr[]={1,2,2,3,4,5}

If it finds 1 in arr, it returns 0, which is fine but if it finds 2 in arr it return 1 and 1 instead of 1 and 2.

for (int q=0; q=size2;q++) {
int rs=secfunc(array1;size1;array2[q])
if(rs>=0) {
cout<<rs << "";

C :: Array Out Of Index

Apr 17, 2014

I was trying to debug a code which was behaving in an abnormal way

Code:

#define NOOFELEMENTS 32
unsigned char array[NOOFELEMENTS];
unsigned char array1[23];
init() {
for(i=0;i<=32;i++)
{
array[NOOFELEMENTS] = 0
}
}

I could trace the above one of the mistakes where the array initialization is crossing the array limits and writing into array[32] which is not available. My question does it overwrite into array1 as it is declared below array or it can write into any other location.

C :: Calloc For Array Of Array With Negative Index

Oct 14, 2014

I have an array of array with negative index. It is an array which has real dimensions [dim_y + 40][dim_x + 40] but the user uses the array like it has dimensions [dim_y][dim_x].

So i see the array's rows lets say from -20 to dim_y + 20 but a user sees only from 0 to dim_y.

First i had global and already defined the dimensions dim_x, dim_y, so i had this:

Code:

int map_boundaries[dim_y + 40][dim_x + 40];
int (*map)[dim_x+40] = (int(*)[dim_x+40])&map_boundaries[20][20]; In fact, 'map' points to 'map_boundaries' , map[0][0] is map_boundaries[20][20].

I did what is posted in the second post here: Negative array indexing - Everything2.com

I want 'map' to be global. Until now i had defined the dim_y and dim_x so that worked fine.Now i just need to read from a user the dim_x and dim_y.

Until now i have global

Code: int **map_boundaries;

and then in main i use calloc:

Code:

map_boundaries = (int **)calloc(dim_y + 40,sizeof(int*));
for(i = 0; i < dim_y + 40; i++){
map_boundaries[i] = (int *)calloc(dim_x + 40,sizeof(int));}

but i dont know how to declare this line now:

Code: int (*map)[dim_x+40] = (int(*)[dim_x+40])&map_boundaries[20][20];

C++ :: Fixing Circular Dependencies With Pointers

Dec 18, 2012

I've been making a project that requires different files to have access to objects declared in other files such that circular dependencies are created. I've done some research and discovered that pointers and forward declarations should be able to fix this.

Example:

File 1 declares variable x, must edit x and y

File 2 must edit x and y, declares variable y

I know this isn't the best example, as you could probably declare x and y in the same file, but please suffice it to say that I'm unable to do that in my project.

C# :: Array Index Management

Oct 27, 2014

I am suppose to make a value to attach to a array and then have it stop on the last one with an error if it were to go past (done more or less).

Problem is I am suppose to use a int to hold the value of the array and then add 1 each time but my question is, if you were to add another number to increase your current array slot, what would that look like as I image that going array[0] + 1 isn't going to make it array[1].

C :: Fixing Command Prompt File Input

Oct 21, 2014

Im writing program for a rail fence cipher that should run from the command prompt and take in two .txt files, one containing the key for how many rails there should be (between 1 and 25) and the other containing the message to be encrypted. Both of those txt files should be entered from the command prompt, taken in with the program's arguments, not asking the user for input I think I have the logistics of how to get the program to encrypt it worked out, but every time I try to run the program it keeps on crashing.

The program should run when I enter this:./railcipher samplekey.txt samplemessage.txt

I'm pretty sure my issue lies within my first few lines of code, with the main(), or with the FILE*, but I dont know what I would need to change it to for it to work properly.

Code:
#include<stdio.h>
#include<string.h>
#include <stdlib.h>
int main(int argc, char **argv[])

C :: Fixing User Input Errors In A For Loop

Mar 6, 2015

So I have to write a step in my program that reads in up to 8 variables. Simple, but if the User submits an invalid value, I have to give an error message and ask him to re-enter the value until he enters a valid number. Here's my while loop that works perfectly:

Code:

while (true) {
printf("
Enter the mark given by Judge 1: ");
scanf("%f", &m1);
if ((m1 >= 0.0) && (m1 <= 10.0)) {
break;
}

[code]...

I'm not sure what to write in the else statement to make the programme understand that it has to repeat the exact same step but without adding 1 to index. Is this possible or do I have to suck it up and just use while loops instead? I'm very new to programming.

C :: How To Concatenate Array Index For Same Elements For Specified Range

Apr 22, 2013

Actually i found some mistakes in my post. So here is the modified version. I want to concatenate the indexes of elements of array that has the same value for specific range.In my case the range is 4

Code:

int element[8]={2,2,0,3,3,0,1,2};
col=4;
int rr;
int qq=0;
for (rr=0; rr<col;rr++){
join_tmp[qq]=rr;
while ((element[rr]== element[rr+1]) ) {
join_tmp[qq]= concatenate(rr+1, join_tmp[qq]);
printf("%d
",join_tmp[qq]);
rr++;
}
qq++;
}

Code:

//FUNCTION TO CONCATENATE INTEGER VALUES OF SAME GROUP IN A COLUMN
unsigned concatenate(unsigned x, unsigned y) {
unsigned pow = 10;
while(y >= pow)
pow *= 10;
return x * pow + y;
}

Code: I want input like
10
2
3
Instead i get
10
2
34

how can i fix it so it will only iterate to the specific range?

C :: Order Values Of Int Array Only Between Two Index Numbers

Mar 16, 2013

I have 2 arrays, one of doubles and other of integers, the doubles have the result of division of two numbers and the array with the ints have numbers that will refer to another array, but it is not important for this problem.

An example:
doubles array: (12,44;12,44;7,22; 12,44)
ints array: ( 4 , 2 , 3 , 1 )

now using my quicksort function i will organize the array of doubles from the higher to the lower, and the ints array will follow the order of the doubles array, the result is :

doubles array: (12,44;12,44;12,44; 7,22)
ints array: ( 4 , 2 , 1 , 1 )

Well, when i have values in the doubles array that are equal, i need to check the ints array and order the ints values, but only the ints that in the doubles array are equals, the final result will be:

doubles array: (12,44;12,44;12,44; 7,22)
ints array: ( 1 , 2 , 4 , 1 )

How i can order the ints array only between an interval that is given by the interval of numbers that are equals in the doubles array?

C++ :: No Check To Determine Whether The Array Index Is Out Of Bound?

Jun 9, 2013

This is an assignment question In C++, there is no check to determine whether the array
index is out of bounds.Design a class myArray that solves the out-of-bound array index problem and allows the user to begin the array index starting at any integer, positive or negative. Every object of type myArray should be an array of type int.

Part 1 processes only int arrays. Redesign the class myArray using class templates so that the class can be used in any application that requires arrays to process data.

I don't understand the second part. should i just change the array from int to char or something?
