I want to write a function that can accept any arbitrary array of doubles and return the index of the first element that is out of order or -1 if the elements are in order. Why my for loop exists immediately after an element is found to be out of order. What is wrong with my code and why?
Code:
int out_of_order(double stuff[], int size)
{
int i;
//run through entire array

I have to write a function called sortMe that sorts the elements of an array in numerical order from highest to lowest values (descending order) or vice versa (ascending order).
The assignment asks to: NOT re-arrange elements in the array; instead, it uses a second array, an array of indexes for the elements in the original array and then sortMe sorts the second array based on the values in the original array. A sorted version of the original array can then be produced with these sorted indexes.
Header of the function sortMe must be as shown below:
void sortMe(int array[],int sortedIndexes [], int size, char mode)
When mode is 'a', the function sorts the array in the ascending order, and when mode is 'd', the function sorts it in the descending order.
Declare and initialize the array array.
Declare the array sortedIndexes but do not initialize it. You are going to play with the array sortedIndexes in the function sortMe.
EXAMPLE:
int array[5]={3, 5,-1,10,0};
int sortedIndexes[5];
sortMe(array,sortedIndexes, 5, 'a');
After the function call, the elements of the array sortedIndexes should be: 2,4,0,1,3.
notice that the function does not e-arrange the elements in the array.
Code:
#include <iostream>
using namespace std;
void sortMe(int[], int, char);
void main() {
int arr[6] = { 14, -5, 5, 0, 22, -99 };

how to use the other array.
The program should store a character array in reverse order then display the reversed array. I have also included in the code that will display the actual characters into the array as it loops through. So I know the characters are being stored, but why doesn't it display the entire string when I call it?
Code:
#include<stdio.h>
int main(){
char str[50];
char rev[50];
printf("Enter Desired Text: ");
scanf ("%[^

Is it just my compiler?
So I been working on this c++ project and I need to be able to take three seperate strings and send them to function to put them in alphabetical order through a-z and use the swap function to return them in order. I been searching for problems like this but I haven't fame across any. I can copy my code onto here as well as a more detailed description of what I'm needing to do onto here if needed.

I am getting the hang of it pretty well. I created a program that asks the user to input arrays. Now, I need to calculate the average of the inputted arrays, and I need to place them in order from low to high.

I want to write a programm that will reverse the order of the numbers in an array (e.g. as an input 1,2,3.5,4 and as an output i want 4,3.5,2,1) . But i have to problems:
1) I do not know how to properly change the type of a numbers inside an array from int to float or double, changing int to float in front of the a[10], does not change anything instead the code does not want to compile then.
2) I also want to make an array of a number of elements typed by a user with use of a "do" loop and how to put this parameter in the code.
Here is my code:
Code:
// ConsoleApplication3.cpp : Defines the entry point for the console application.//
#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[]) {
int a[10], i, n;
int pom;
do {
printf("number of elements in an array a: n = ");

Implement a recursive function named void printBack(DoublyLinkedNode<T>* node) for the class DoublyLinkedCircularList which will print out the elements in the list from back to front. The function is initially called with the first node in the list. You may not make use of the previous(prev) links
This is my solution where I got 2 out of a possible 3 marks:
template<class T>
void DoublyLinkedCircularList<T> :: printBack(DoublyLinkedNode<T>* node) {
if(node->next == NULL) //Correct- 1 mark
return 0;
else
printBack(node->next); //Correct - 1 mark
cout << current-> element << " ";
}
I am trying to develop a function which prints a binary tree using post-order traversal (left, right, root) but I am experiencing some troubles. The code is compiled but when I run the program it crashes right before printing the post-order traversal.

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?
So I try to sort an array with qsort and then save the new order, so this means if I have a list like:
4 3 7 2
[0] [1] [2] [3],
after sorting it becomes:
2 3 4 7
[3] [1] [0] [2] <== this is what I want to have!
Code:
void qsort_my(int *a, int l, int r, int *array_order) {
int j;
if( l < r ) {
j = split( a, l, r, array_order);
qsort_my( a, l, j-1, array_order);
qsort_my( a, j+1, r, array_order);

But my problem is that the list gets sorted, but the indexes do strange stuff. When I run with this list:
4 8 14 1 2 1 22 12 2 14
Pos: 0 1 2 3 4 5 6 7 8 9
I get:
1 1 2 2 4 8 12 14 14 22
Pos: 1 0 1 0 0 5 7 6 5 6
And with some printfs I noticed, the first two calls of split it is fine but then strange things start to happen, what I do wrong?
I am trying to read information in from a file, each line of which contains a name in the form 'last, first middle'. I can successfully open the file and read it into an array that is roughly 2500 string in size. The problem comes when I try to sort the array into alphabetical order. I am using a sorting algorithm that we were instructed to use, found in our book. It is shown in the code. I would add the file that needs to be opened, but it is a few thousand lines long.
The error I am getting is:
Unhandled exception at 0x00A28628 in PeopleSearch.exe: 0xC0000005: Access violation reading location 0x00CC400C.
and I know it has to do with the sorting algorithm from using break points and running the program with that section commented out. I am stumped to why it is giving this error, as it seems that it is trying to access the array outside of the bounds of the array, but it shouldn't be
Here is my code:
#include<iostream>
#include<string>
#include<fstream>
using namespace std;
int main() {
string NameArray[2500], filename; //declare array and file to open

I need fastest method to reverse order of bytes in my char array.
For example i have:
unsigned char buf[8];
// consider data stored in buf is 88 77 66 55 44 33 22 11
// how to reverse it to: 11 22 33 44 55 66 77 88
// currently i can do it by equal assignment , i make another buf like:
unsigned char buf_ok[8];
[Code] ....
// This does reverse the bytes as i want but its very slow , i am looking for fast method ..
understand the details of what this function actually do?
View 7 Replies View RelatedI am writing a function called swap that sorts the elements of an array in order from highest to lowest values where they descend and ascend. A particular thing about this function is that swap does NOT re-arrange elements in the array so it just uses a second array of indexes for the elements in the original array and then swap sorts the second array based on the values in the original array. A sorted version of the original array can then be produced with these sorted indexes. You can declare and initialize the original array without any user input.
For example, int arr[10] = {1, 5, 22, 14, 6, -5, 7, 9, 12, 15 };
Header of the function swap must be as shown below: void swap(int array[],int swapedIndexes [], int size, char mode) When mode is 'a', the function sorts the array in the ascending order, and when mode is 'd', the function sorts it in the descending order. int swappedIndexes[5];swap(array,swappedInde… 5, 'a');
So far I have this code that randomly generates arrays of 10 elements and I found the max and min, but I am confused on what to do about the swapping part? Also, how to make the numbers ascend or descend in numerical order?? Here is what i have done so far:
#include<ctime>
#include <iostream>
using namespace std;
int min(int [],int);
void max(int [],int , int &);
void main()
{ srand(time(0));

I have a pre-declared array which sorts strings to it's alphabetic order and want to change it so it reads from stdin.
char *array[] = {"aaa", "ccc", "bbb", "ddd"}
I tried doing something like this:
for (i = 0; i < length; i++)
scanf("%s", &array[i]);
I just can't bring it to work. Another thing is, the input is a a bunch of strings separated by commas and ends with a period. Since I have to make a working C model which gets translated to assembly language later on I can't use functions like strtok.
//Build a program that uses a single-dimension array to store 10 names input by a user.

I'm trying to use a priority queue sorting in reverse order to take a vector or 2d array. The problem is that I want to sort by the vector/array cell value but keep the reference to the vector/array index of the value. I don't know quite howto keep them both related so when I pop. I can find the corresponding cell.
