C :: Function That Merge Content Of Two Sorted Arrays Of Double Type Values
Nov 4, 2013I need to write a function that will merge the content of two sorted arrays of type double values. The function should not assume that both its input parameter arrays are the same length.
Here is my program so far - I know there is alot of errors and mistakes:
Code:
#include<stdio.h>
void merge(int firstArray[],int secondArray[],int size) {
int mergedArray[size],i=0,j=0,k=0;
while(i<size||j<size) {
if(i==size) {

C :: Getting Seg Fault At Read Function

But the problem is i get a seg fault at the read function.
C :: Segmentation Fault In Call To Recursive Function
Apr 12, 2014Task: To create a recursive function to sort elements in an array of integers.
The function must start the sorting from the first element, and the recursion calls must go on until the last element in the array is sorted. In each step of recursion, the function must work only with the subset of array elements that have not been sorted yet.
Problem: I am getting a 'Segmentation fault: 11' in the recursive call to the function (please, see the code below).
Environment: Mac, OS X = Mavericks
Code:
////////////////////////////////////////////////////////////////////////////////
////////// Recursively sorting an array of ints.
////////// Arguments: array, array size, index from where to start sorting.
void sort_incr_array_int_recursive(int a[], int size, int i){
int tmp, idx_small, small = a[i];
// Locating the smaller element in the array section.

C :: Segmentation Fault On 2nd Call Of Specific Function
Sep 21, 2014I`ve almost finished the program I am working at ( not commercial, it`s for me ). And I still can`t get what is wrong. I get segmentation fault on 2nd call of specific function. I have 2 lists of strings. One for directories, one for files. A function to walk a directory recursively, and to add to front in both lists respectively for files and for dirs. Then do something on these files. Here is my code for the functions I am using and will explain where I am failing.
DList.cpp Code: DList* createList(const char* message) {
DList* dl = (DList*)malloc(sizeof(DList));
dl->head = dl->tail = NULL;
printf("List created at %p; message:[%s]
", dl, message);
if ( dl != NULL ) return dl;
else return NULL;
[code]....
What fails? Well after the first press of p/P, it lists and prints the dir/filse. On second press it gives me a segphault. Really no idea what I got messed up. I`ve listed all the functions I am using ....
C++ :: Segmentation Fault - Memory Error When Looping Over Function?
Mar 24, 2014It is been several days that I am stucked with the segmentation error and I do not know anymore what to do I try to do a loop over my function but it is working only for my first iteration. Here the code:
#include <iostream>
#include <cstdio>
#include <cstdlib>
[Code].....
I would like to iterate over solvep (since h is changing at each iteration..I usually add other fct but now I try to debug why the loop is not working.).The first iteration is working fine but not the other iterations.
C :: Function That Sorts Dictionary List Alphabetically - Segmentation Fault (core Dumped)
Oct 9, 2013Write a function that sorts a dictionary list alphabetically. Here's my code:
Code:
#include <stdio.h>
#include <stdbool.h>
struct entry
{
char word[15];
char definition[50];
[Code] ....
It's compiling ok, and displays the first call to the printf function from main. However, after this I get the 'Segmentation fault (core dumped)' at the terminal, presumably from the call to the dictionarySort function.
I had a little look around and found it is something to do with non-existent or not available memory addressing, I think? Even so, I can't figure out what is causing the issue in my code.

C :: Merge Two Arrays Without Need To Iterate

C :: Subarrays For Merge Sort
May 15, 2013Code:
/* Mergesort: Use merge() to sort an array of size n */
#include <stdio.h>
#include <stdlib.h>
void mergesort(int key[], int n) {
int j, k, m, *w;
for (m = 1; m < n; m *= 2)
[Code] .....
Question : Modify mergesort() so that it can be used with an array of any size, not just with a size that is a power of two. Recall that any positive integer can be expressed as a sum of powers of two. For example,
27 = 16 + 8 + 2 + 1
Consider the array as a collection of subarrays of sizes that are powers of two. Sort the subarrays and then use merge() to produce the final sorted array.
I tried so many algorithms and all failed!! What i dont know is how to create subarrays ?

C++ :: Merge Sort - Top Down Versus Bottom Up
Apr 28, 2014I tried to keep the coding style as similar as possible. I tested these with 4 million (4x1024x1024) 64 bit unsigned integers, Visual Studio 2005, 64 bit mode, Win XP X64, Intel 2600K 3.4ghz cpu. The average time for top down = 3.7 seconds, bottom up = 3.5 seconds.

C :: Implement Merge-Sort Algorithm?
Jul 24, 2013I'm trying to implement the Merge-Sort algorithm. I only had the pseudocode for it and have some problems coding this into C.
I have only covered pointers recently and I tried using them, which did not work. I started with the code for the merge algorithm and only used a 10 element array, which was already divided into two sorted subarrays:
Code:
#include <stdio.h>#include <stdlib.h>
int main() {
int a[5]={1,5,6,10,13}, b[5]={4,8,9,10,14},c[10], *i,*j,k;
[Code].....
This is the result that I get:
Code: 1 4 5 6 8 9 10 10 13 0
So I think the problem occurs because in the second to last loop i is incremented again, but the end of the array is already reached, and the compiler has no element a[6] to compare with *j in the last run of the loop. Is there generally a better way to implement Merge?

C++ :: Merge Two Sorted Files Failing
Oct 7, 2013I have to merge two sorted files. Algotrithm that i'm using is below, but it reads not all the numbers in the files, and stops, even the files contain the same number of elements. What is wrong, I can't understand.
ifstream f1("E:desc1.txt");
ifstream f2("E:desc2.txt");
ofstream f("E:desc.txt");
cout <<endl<< "Nuerele sortate: " <<endl;
int n1, n2;
f1 >> n1;
f2 >> n2;

desc1.txt is:
99 97 95 93 91 89
and desc2.txt is:

C++ :: Merge And Sort List Of Strings?

File 1:
red, apple
green, truck
blue, car
yellow, ball
orange, candy
File 2:
gold, necklace
green, tree
yellow, sticker

red, bag
I am looking for the following output:

C/C++ :: Merge-Sort With X And Y Coord From File
Apr 17, 2014So I have a file with 2 float numbers like this
0.041631 0.176643
0.364602 0.091331
0.092298 0.487217
0.526750 0.454433
0.233178 0.831292
0.931731 0.568060
0.556094 0.050832
0.767051 0.018915
0.252360 0.298197
0.875981 0.531557
I would like to place the first column in one array and second in another. I am using the merge sort and merge algorithm from my book to sort the first column (x-coord) in descending order and the second column (y-coord) in ascending order. The output would look like this.
(where, x, y)
6: 0.931731 0.018915
10: 0.875981 0.050832
8: 0.767051 0.091331
7: 0.556094 0.176643
4: 0.526750 0.298197
2: 0.364602 0.454433
9: 0.252360 0.487217
5: 0.233178 0.531557
3: 0.092298 0.568060
1: 0.041631 0.831292
I am ignoring the where(line number) for now. The error I get is: cannot convert 'points_struct*' to 'int*' for argument '1' to 'int mergesort(int*, int, int)'.
So my question is how to get my points_struct arrays to work with the algorithm I have from book. Here is what I have so far.

C Sharp :: How To Merge Assembly Info In C#
Mar 15, 2013I have a solution with multiple projects. Each have an assemblyinfo.cs. file Each of these files have a section that is particular for each project like
[assembly: AssemblyTitle("Activity Manager")]
[assembly: AssemblyDescription("Activity Manager for .Net 3.5 Framework")]
I also have a global assemblyinfo.cs file which has items that are the same for all projects like
[assembly: AssemblyCompany("MyCompany")]
[assembly: AssemblyCopyright("2010 MyCompany Ltd")]
[assembly: AssemblyVersion("11.1.1.18824")]
[assembly: AssemblyFileVersion("11.1.1.18824")]
Is there a way of combining the 2 or including the global section in the assemblyinfo.cs for each project.
In C++ I can do a #include but that doesn't work in c#.
