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/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 :: 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# :: 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 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

Visual C++ :: Index Position In Array

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?

C :: How To Stop Passing Char Array Index As Pointer

Dec 23, 2013

I am trying to write a light weight printf style function.

I have got this far:

Code:

void println(const char *txData){
LOG(__PRETTY_FUNCTION__);
UARTPuts (LPC_UART0, txData);
}
void miniPrint(const char *format, ...)
{
unsigned int index = 0;
va_list argptr;
va_start(argptr, format);

[Code]....

I understand why I think. When I am passing the reference to the array possion it is outputting everything up to the next /0. So my question is how do I stop it?

I dont have much choice as to how the output wants it:

Code: void UARTPuts(LPC_UART_TypeDef *UARTx, const void *str)

Thats library code, so I dont want to change it. I.e I have to pass an address into println.

C :: Write A Function That Finds Integer In Array And Returns Its Corresponding Index

Mar 20, 2013

I have an assignment which requires me to do the following:

Required to write a function that finds an integer in an array and returns its corresponding index. The function must be called findNumber. It must have FOUR parameters:

- The first parameter is the array to be searched
- The second parameter is the integer to be found within the array
- The third parameter is the size of the array
- The fourth parameter is an integer that indicates whether the array is sorted. A value of 1 means the array is sorted; a value of zero means the array is not sorted.

Since a function can only return one value(To return the position of a required integer in an array in this instance) I have tried to make use of pointers to try and return a value stating whether the array is sorted or not.This is my code : (It compiles perfectly but it does not produce any outputs)

Code:

#include <stdio.h>
#define SIZE 10
size_t findNumber(int *sort, const int array[],int key,size_t size);
int main(void){
int a[SIZE];
size_t x;
