C :: Subset Combinations - Select All Numbers Right Or No Numbers Right
Dec 22, 2013
I need a list generated of all possible subset combinations for the set 1,2,3,4,5,6,7,8,9,10,12. Select six. Numbers cannot repeat.
Example subset: 1,2,3,4,5,6 (six selected, no repeats).
Example of what I dont need: 1,1,2,2,3,3,4,4,5,5,12,12 or 1,1,1,1,1,6.
I will also need the opposites removed, meaning...if I have 1,3,5,7,9,11 then I need 2,4,6,8,10,12 eliminated from the final list.
This is for a game, where you must select all numbers right or no numbers right.

The code below will generate combinations of numbers from 1 to 25 in an 15 numbers array. The only filter I've applied is that the sum of all the numbers in the vectors divided by 15 needs to be between 13 and 14.
I would like to count how many consecutive numbers there are in one combination, so that later i can apply another filter.. for example:
1 3 4 5 6 8 10 13 14 16 17 18 19 20 25
3 + 4 = 1
4 + 5 = 1
5 + 6 = 1
13 + 14 = 1
16 + 17 = 1
17 + 18 = 1
18 + 19 = 1
19 + 20 = 1
_____________
Count = 8, in this case..
I think it's not very difficult to do, but i just can't see how to do it.
#include <iostream>
#include <vector>
#include <numeric>

The 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 ) {

User enters sentence "The Smiths have two daughters, three sons, two cats and one dog." (The numbers may change depending on what the user chooses to enter. He told us the range would be from zero to nine.) and we have to convert the written numbers within the sentence into actual decimal numbers and print out the new sentence. Ex. The Smiths have 2 daughters, 3 sons...etc.
I have written the following bit of code which reads the string and finds all the "written numbers" but I am not sure how to proceed from there. I am stuck on how to print out the new sentence with the converted numbers as my professor mentioned something about creating the new string using dynamic memory allocation.
Code:
#include <stdio.h>#include <string.h>
int main () {
char A[100];
int length = 0;
int i;

Find all the prime numbers between a given pair of numbers. Numbers should be read in from an input file called "numbers.txt" and find all the prime numbers between them. Store the prime numbers in an array, then sort the array from greatest to least. Display the array before and after the sort.
I'm stuck on how to put the prime numbers into an array.
The input file has the numbers 1 & 100.
Here's what I have so far.
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ifstream fin;
fin.open("numbers.txt");

I'm working on this program that I have to design a class Numbers that can be used to translate whole numbers to the English description of the number.
Now this is what I got so far:
#include <iostream>
#include <string>
using namespace std;
class Numbers {
private:
int number;
static string ones[];
static string tens[];
[Code] ....
The program seems to work. However its not giving me the right number description,
Example:
Please enter the amount you would like translated into words: 5
six dollars
please enter another number: 10
eleven dollars
please enter another number: 20
thirty dollars
please enter another number: 30
forty dollars
please enter another number: 100
two hundred dollars
please enter another number: 150
two hundred sixty dollars
please enter another number: 500
six hundred dollars
please enter another number: 1000
two thousand dollars
please enter another number:

I wrote a program which sends a starting and ending range to other processes and the processes calculate the prime numbers in that range and return the count of prime numbers to the head process, process 0.

Write 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);

i have trouble with comparing two of the biggest numbers out of four numbers. Im working on an assigment with a dice game where i need to tell the computer the following;
"if the biggest number out of dice_three and dice_four is the same number as the biggest of dice_two and dice_one, then loop1=true"
this is how i have been writing it so far ;
if
(MAXA(dice_three,dice_four) == MAX(dice_two,dice_one)){
lopp 1=true;
}
(as seen) i am using:
#define MAX(dice_one,dice_two) ( (dice_one) > (dice_two) ? (dice_one) : (dice_two) )
#define MAXA(dice_three,dice_four) ( (dice_three) > (dice_four) ? (dice_three) : (dice_four) )
to calculate which one is the biggest number out of the two pares. The code i have been writing so far seem to have the wrong syntax.

A program is a set of all subsets of this part of the show. Users can enter a number., For example, if n = 2 the output looks like this:
{}
{1}
{2}
{1,2}
or for n=3 we have:
{}
{1}
{2}
{3}
{1,2}
{1,3}
{2,3}
{1,2,3}
meantime this program should be solved with tow way. recursive function and Non-recursive.Can also be used in solving the problem of bitwise operations.

A few days ago I got a "bright idea" to see if I could match a string, with an arbitrary length from 1 to 12, to its formulated sequence by using an algorithm to find all possible combinations of the integer combinations from 0 to 9 at each length (1 to 12).
Example: Desired numerical combinations from integers 1 to 3:
At Length 1:
1, 2, 3
At Length 2:
11, 12, 13, 21, 22, 23, 31, 32, 33
At Length 3:
111, 112, 113, 121, 122, 123, 131, 132, 133, 211, 212, 213, 221, 222, 223, 231, 232, 233, 311, 312, 313, 321, 322, 323, 331, 332, 333
And so on until the nth length (in my case a length of 12).
First off, I would like to say that this is not as easy as I thought. I clearly underestimated the problem seeing as I've spent hours attempting to write a working algorithm, but feel like I've made no progress.
Here are a few of my attempts:
Attempt 1:
#include <iostream>
#include <algorithm>
#include <math.h>
#include <string>
[Code]....
I can't exactly explain this one. It works if the length is 2 or less; however, the order of the output is horrendous.
Attempt 3: I tried using recursion, but only found myself getting more and more lost the further I tried developing my function. Cannot find my work for this attempt.
I would really like to figure this out on my own, but I am very stuck as you can see. I also lack time that I can spend working on this since im a full time student.

I need to create a function that outputs all possible binary combinations. I'm really stumped on this. I have to do it with nested loops, and am not sure how to go about it. Below is what I tried so far.
The output should look like this:
00000000
00000001
00000010
00000011
00000100
...
11111110
11111111
Code:
void outputBinary(){
int a[2][2][2][2][2][2][2][2];
for (int i = 0; i < 2; i++){
for (int j = 0; j < 2; j++){

How to find all possible combinations of coordinates on a 2d grid with a given sum. The sum is not fixed!
E.g. N=nxm=25 thats our grid.
The sum=distance between points on a grid.
For two points distance=|(x1-x2)+(y1-y2)| point A(X1,Y1) B(X1,Y1)
My interest is to know how to find the combinations of coordinates with a given sum, it doesn't matter how many points are there.
If i enter the sum e.g sum=7 and the program has to show all possible combinations which gives the sum of 7 the number of point does not play in row they might be two or maybe more.
