Mar 6, 2015suppose you we given a file containing sorted numbers
ie
1
2
4

Jun 11, 2014I have a .txt file which I want to read from and then write a new text file, this time with sorted lines. It is easy to sort one value, but what about sorting entire lines based on one value?
I want to sort the lines based on the FIRST value.
Example text file contents:
values;data
5.01 100
2.9 342
2.69 43534
10.1 43
6.8 45324
Output: Text file containing
2.69 43534
2.9 342
5.01 100
6.8 45324
10.1 43
It's easy to do this if there was only 1 number on each line, but I do I sort all the lines based on the first number in each line?

C++ :: Output Data From Two Sorted Arrays Into One File?
Apr 7, 2013I am trying to output data from two sorted arrays into one file(which should also be sorted). The program works for most of the data, but after it reaches a certain record begins outputting garbage. I'm sure part of the problem is that I don't know what to include in my while loop that outputs to the file.
#include <iostream>
#include <fstream>

C :: Won't Print Numbers Sorted When Use Print Function
Nov 17, 2013I am making a program where the user enters numbers into an array and then a number,x. The array is sorted, then x is inserted into the appropriate place. I wrote my selection sort
Code:
void Sort(int ary[], int size)
{
int temp;
int smallest;
int current;
int move;
}

put it wont print the numbers sorted when I use my print function, just the unsorted numbers.
C++ :: Read Stream Of Numbers From A File And Writes Only Positive Numbers To Second File
Mar 27, 2013Write a program which reads a stream of numbers from a file, and writes only the positive numbers to a second file. The user should be prompted to enter the names of both the input file and output file in main(), and then main() will open both files. Another function named process() must then be called to read all the numbers from the input file and write the positive numbers to the output file. Note that you must pass the open stream variables for each file as arguments to the process() function, and that you need to (always) double check that the files opened successfully before using them.
This is what I have so far but its not working out!
#include <iostream>
#include <fstream>
#include <stdlib.h>
using namespace std;
int process(ifstream &inf, ofstream &outf);

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:
100 98 96 94 92 90
and I'm getting this:
100 99 98 97 96 95 94 93 92
C++ :: Parallel Scan Of Sorted Sequences?
Feb 4, 2015I need to take an unknown amount of sorted files and then output any number that is in at least half of them... I know I need to read in the files to a vector and then iterate through them all at the same time looking at the lowest number first and so on. But I am stuck at the point of taking an unknown amount of files and putting them in a container.
This is what I have so far but the vector isn't working and I think I should be putting each file into its own vector.

C :: Sorted List - Why Value Of Void Pointer Change
Feb 16, 2014I have a the following in a header file.
Code:
struct SortedList{
void * data;
struct SortedList * next;
struct SortedList * previous;
int (*compareFunc)(void *, void *);
void (*destructor)(void *);
[Code] ....
In a .c file, I implemented the SLCreate function.
Code:
SortedListPtr SLCreate(CompareFuncT cf, DestructFuncT df){
struct SortedList item;
item.data = NULL;
item.next = (struct SortedList *) malloc(sizeof(struct SortedList));
[Code] ....
In main.c, I try to do the following:
Code:
SortedListPtr list = SLCreate(&compareInts, &destroy);
A bunch other code that does not alter list or it's contents at all.
struct SortedList item = (*list);
void * data = item.data;
if (data != NULL) {
printf(Why did data become not null???
"); }
How come my variable data became not null anymore when I haven't altered it at all....

C/C++ :: Adding Linked List In Sorted Order
Sep 22, 2014I am currently trying to add to a linked list in sorted order but I have reached an impasse. I can get it to add in sorted order if it belongs in the beginning or second in the list. If i were to type in 9 then 4 i would get 49, but if i type in 5 it changes it to 559. I'm just at a loss and need some sort of direction.
#include "singly_linked_list.h"

C++ :: How To Pass Array To Function And Return It As Sorted Vector
Sep 17, 2014How to pass my array to the function and return it as a sorted vector. I'm kind of lost with the functions part.
Problem: Write a program that performs a sorting routine as discussed in class. Create an array of 10 integers (e.g., 63, 42, 27, 111, 55, 14, 66, 9, 75, 87). Pass this array to a separate function that sorts the integers and returns a vector containing the sorted integers. Use either the SELECTIONSORT algorithm or the INSERTIONSORT.
Code so far:
#include <iostream>
#include <string>
#include <vector>
#include <cmath>
#include <cstdlib>

C Sharp :: Error Concerning Sorted List Not Being Accessible Due To Its Protection Level
Oct 7, 2012For school we have to create a blackjack game using windows form. I had to store the images of each card into a sorted list so i created a class called cardList and created a constructor which contained the the sorted list called cards. So it looks kinda like this:
public class cardList : Form1
{
SortedList cards = new SortedList();
public cardList()
[Code]....
There's probably a few other errors, I'm still trying to figure this whole c# thing out. why the error tells me (on the line that contains c.cards.GetByIndex(cardNumber);) that cards is inaccessible due the its protection level.

C++ :: Pointers And Arrays - Program To Display Sorted List And Average Of Scores With Appropriate Headings
Apr 22, 2014I am writing a class that dynamically allocates an array that holds a user-defined number of test scores (test scores go from 0 to 10 both included). Once all the test scores are entered and validated (values only between 0 and 10, both included), the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates theaverage of all the scores.The main program should display the sorted list of scores and the average of the scores with appropriate headings.
