C++ :: 250000 Numbers - List Of Subsets
Mar 7, 2014Given up to 250000 numbers i have to produce a list of subsets(first of one element, then of two etc). Is there an easy way using a bitset<250000> ?

C++ :: Divide Set Of Numbers Into Two Subsets Where Difference Between Sums Of Subset Is Minimal
Feb 28, 2013The problem is that you have a set of numbers and you need to divide that set into two subsets where the difference between the sums of the subset is minimal.
Example: a set of numbers {1,5,9,3,8}, now the solution is two subsets, one subset with elements {9,3} and the other {8,5,1} the sum of the first one is 13 and the sum of the second is 13 so the difference between the sums is 0. The result shows the difference between the sums.
Another example: a set of numbers where the difference between the subsets cannot be zero, {9 51 308 107 27 91 62 176 28 6}, the minimal difference between the two subsets is 2.
I want to know how the function finds the two subsets, it works great because I've tested it for up to 300 inputs which sum adds up to 100,000.
Code:
#include <iostream>
#include <stdio.h>
#include <math.h>
#include <stdlib.h>
#include <limits.h>
using namespace std;
int BalancedPartition ( int a[] , int n ) {

C :: Find All Subsets With Sum Of X
Oct 20, 2013I am working on a homework lab in which we have to find all the subsets equal to a given sum from an array of numbers.For example, an array of 7 numbers (1, 3, 4, 6, 7, 10, 25) with a sum of 25 would be (1, 3, 4, 7) and (25)...We are supposed to use dynamic programming to solve this.Now using the code below that we went over in class (Sedgewick's subsetSum), I understand how to this finds the first subset that adds up to the sum given. What's stumping me is how to find multiple subsets.
Code:
main(){
// Get input sequence
int n; // Size of input set
int m; // Target value
int *S; // Input set
int *C; // Cost table
int i,j,potentialSum,leftover;
}
[code]....
In class the teacher said it would be mainly just modifying the code we went over in class.

C++ :: Output Numbers From A Set Of List Not Used
Mar 25, 2014This is one part of my program, I need a loop that checks through the input(specifically the agent numbers) and then outputs the agent numbers that aren't in the input, from 1 to 20(because there should only be 20 agent).
My input is :
1 3 250.00
2 0 0
15 1 1000.00
3 4 300.00
12 2 500.00
1 2 300.00
3 4 115.00
21 3 400.00
-1 4 250.00
15 1 200.00
9 5 -150.00
18 2 140.00
13 2 550.00
the first numbers are the agent numbers so 1 , 2 ,15 are agent numbers and out output for agents who didnt participate are : 2 , 5 , 6 , 7, 8, 9, 10 , 11 , 14 , 16 , 17 ,19 20
this is the code ive wrote but its not working.
void not_part() {
ins.open(in_file);
int i=0;
int sum=0;
cout<<"AGENTS WHO DID NOT PARTICIPATE IN THE CAMPAIGN"<<endl;
cout<<fixed<<showpoint;

C++ :: Storing A List Of Numbers In Integer?
Dec 6, 2014I am writing trying to store a list of numbers into an integer as bits. So far I have this:

integer = integer<<2
integer = integer | n;
convert(integer));
I want it to store the integers as bits so that I am move them over and store them farther down the row as more numbers are added, but instead each new number is being added to the previous and I'm just getting a larger integer. Is this even a feasible way to store integers within an integer?
C++ :: Take Numbers And Add One By One As Integers In Linked List
Aug 21, 2013Let's say that in a txt file named hot.txt, I have this:
12,23,32
And with ifstream I want to take those number, adding one by one as integers in a linked list.
ifstream myList;
char* p= new char;
cin>>p;
myList.open(p);
if(myList.is_open()) {
char* x =new char;
[Code] ....
I know this part is quite wrong :
myList.get(x,256,','); // dafaq
int num=atoi(x);
list->addOrdered(num);
What I wanted to do is to stop before each comma and take that character and store it in the linked list and continue until the end of the file, but I couldnt.

C++ :: Program To Extract Special Code From A List Of Numbers
Nov 1, 2013I am a beginner and I ALWAYS have the toughest time doing I/O files. It's extremely frustrating. It "seems" it should be so simple. The program should find a code from a list of numbers. These numbers are from 0 - 9, and after each number is a space in the file. Your job is to extract a special code containing only 10 of those numbers. For the number to be part of the code, it should be divisible by 2. After extracting 10 numbers divisible by 2 for the code, write those 10 numbers to the file to form the expected code.
Input file is ("question.txt")
Output should be ("code.txt")
Should this contain a "for loop" or If/else ?
Here's what I did . .
/
// int numbers, total, counter;
ifstream inFile;
inFile.open ("question.txt");
outFile.open ("code.txt");

C++ :: Read List Of Numbers From A File And Then Print Out In Reverse Order
Apr 6, 20131. Construct a class diagram that can be used to represent food items. A type of food can be classified as basic or prepared. Basic food items can be further classified as meat, fruit, veg or Grain. The services provide by the class should be the ability to enter data for new food, to change data for food and to display existing data about food.
using this class definition write a main program to include a simple menu that offers the following choices:
1. Add food
2. Modify Food
3. Delete Food
4. Exit this menu
2. Read a list of numbers from a file and then print them out in reverse order. State whether the list is palindromic or not.

C++ :: Convert List Of Binary Numbers From A File Into Decimal And Print To Screen
Sep 23, 2014I am trying to make a program that will convert a list of binary numbers from a file into decimal and print the decimal to the screen. I have no problem doing the conversion, the problem comes up when our teacher wants the input file in a format as such:
3
10110101
11111111
10101010
The first number is supposed to tell the program how many different 8bit strings it is going to have to convert, and then the following lines are those binary numbers.
I am not very experienced with file inputs, and I know how to open files and read lines in.. The problem is, how to say "ok the first line says 3, so now I have to convert the next 3 lines" . I am assuming it is just a simple loop that I am missing....

B. The sum of all the numbers in the file.
C. The average of all the numbers in the file.
D. The largest number in the file.
E. The smallest number in the file.

C++ :: Why Does HP / Microsoft STL List Use Same Structure For List Head And Node
Apr 23, 2013From HP / Microsoft (Visual Studio C++) <list>:
Code:
struct _Node
{ // list node
_Genptr _Next; // successor node, or first element if head
_Genptr _Prev; // predecessor node, or last element if head
_Ty _Myval; // the stored value, unused if head
};
The stored value is wasted space for the list head. Is there any advantage to implementing list using the same structure for a list head and node?
C :: Linked List / Adding Element To Beginning Of List
Dec 31, 2014Code:
// Write a function called insertEntry() to insert a new entry into a linked list.
Have the procedure take as arguments a pointer to the list entry to be inserted (of type struct entry as defined in this chapter), and a pointer to an element in the list after which the new entry is to be inserted.
// The function dveloped in exercise 2 only inserts an element after an existing element in the list, thereby prenting you from inserting a new entry at the front of the list.
(Hint: Think about setting up a special structure to point to the beginning of the list.)
#include <stdio.h
struct entry1 {
int value;
struct entry1 *next;
};
[code]...
This is a working version of the exercise, but I don't think I'm doing what's asked. I was able to add an element to the beginning of the list using an if statement, not creating a special structure that points to the beginning of the list. How would I go about creating a special structure that points to the beginning of the list to add a new element at the beginning of the list?
