C# :: Sort Array Of Random Numbers By Passing It To Method
Jun 28, 2012
I am trying to sort an array of random numbers by passing it to a method Sort(), sort the array, and then pass the entire array back to the calling program. Each time I run this though, the array doesn't seem to sort. I'm not sure if the problem lies with my sorting algorithm or if it has something to do with calling the function.
Code:
static void HighAverage(int[] a) {
for (int i = 0; i < a.Length; i++) {
if ((i + 1) % 10 == 0 && i != 0)
[Code].....

i'm trying to fill an array with random numbers and then sort them via bubblesort. it seems to work so far. the problem is, that i seem to get the same numbers for the same input. somehow the randomness isn't working.
Code:
#include <stdio.h>
#include <stdlib.h>
int main() {
int a, b, c, d, e, f;
}

I'm trying to sort random numbers in ascending order and I was wondering how I should go about that.
Here's what I currently have.
#include <iostream>
#include <vector>
#include <cstdlib>
using namespace std;
[Code].....
I'm trying to put our algorithm between the ////'s. We're only allowed to use for loops also. What I currently have is the minimum number finder and the use of temp to find the values. However, it doesn't seem to be working.

Why my sort is not working. Also, I want to keep the same random numbers for the continuation of the program, I don't want new randomized values when I display the table.

I have to create a program that accepts 10 numbers from user, and then I display a list of the numbers, the smallest one and the higher number. I have problems with displaying the smallest and higher number, I tried to Array.Sort and Array.Reverse, but I don't know what I'm doing wrong, this is my code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace SmallAndLargeGUI
[Code] ...
Also I tried to set
if (x == 10)
numberTextBox.Enabled = false;
to block the textbox when the user has entered 10 numbers, but didn't work either...

I'm passing an array into this function and it's taking the item at index 0 and replacing the rest of the array with it.
Code:
void generic_sort (void *arg, size_t num, size_t size, int (*cmpfnc) (const void *, const void *)) {
for (int i = 1; i < (int)num; ++i) {
int j = i;
char *tmp_address = malloc (sizeof (arg));
tmp_address = (char *)arg + j * size;

My programme is trying to create a random array of 100 ints between 0 and 250, sort them and print them.
Here is my code:

I have an Array of [3] [3] and by default the numbers will be in following format, which is not visible -
1 2 3
4 5 6
7 8 9
I need to get the numbers from User, example -
0 4 0
9 1 0
5 0 7
if a User fills random numbers like above, then my program needs to fill the '0's with the missing numbers from 1 to 9 in an ascending order as below -
2 4 3
9 1 6
5 8 7
This is my problem and i need a logic for this in C++.

I am making a custom linked list (for fun!) and want to implement a sort method that sorts the stored data using the stored types > and < operators (will require the type to have these operators overloaded)
What is the best way to do this? I guess the first thing one might jump to would be to compare the current node with the the node to its "right" see if one is greater than the other. Then keep iterating through the list until you don't swap any more nodes. However I am thinking there is probably a more efficient way to do this. Here is my code so far:
#ifndef LIST_HPP
#define LIST_HPP
#include <string>
[Code].....
Surely there is a way to sort with only one iteration through the list?

So we're having an assignment for school where you code a Roulette game which simulates you playing and you can choose how many times you "play" to check how many times you'd win (if that makes any sense, im german :P)
Anyways, the problem is how do i store all the random generated numbers in an array while NOT doing this (it's just a snip):
Code:
void randomzahl(void){
int i;
int zahl5[5];
int zahl10[10];
int zahl100[100];
int zahl1000[1000];
int zahl10000[10000];
if(runden == 5)

i have a programming problem and i am unsure of what the final part is.the question is:
Write a program that fills an array with 10 random numbers between 1 and 20, displays the 10 numbers, and finds the sum of the 10 numbers. Call the getData, displayData, and getSum functions from the main function. Output the sum from the main program by calling the getSum function within a printf statement.
i am just really unsure of what this is--getData, displayData, and getSum functions from the main function. Output the sum from the main program by calling the getSum function within a printf statement.what i have got so far is;
Code:
#include <stdio.h>
#include <stdlib.h>
#define ARY_SIZE 10
int main() {
int randomNumbers[ARY_SIZE], sum = 0, i;

Below is my code for a program that is suppose to generate and display six unique random numbers (between 1 and 54). The issue seems to be in my check for duplicates. I know what I am doing wrong but can't seem to find a way to fix it. I think it is getting stuck in an endless loop because the way I have written it looks like it checks the first value against itself which will of course look like a duplicate everytime.
Code:
#include<iostream>
#include<ctime>
using namespace std;
//function prototype

This compiles fine but when I run the .exe for the first time an error message comes up saying program has stopped working. If I run the program again without recompiling it seems to work as expected.

My C programming class wants us to write a program to read integers into an array, sort the numbers and print out the occurrence of each number. I've tried everything that I can think of but the core dump is still occurring.
void countValues ( FILE *inf, int list[], int size ); /* Function prototypes. */
void printFrequencies( const int list[], int size );
int main (void) {
int status = EXIT_SUCCESS; /* defaulting status to success. */
FILE *inf = fopen( "numbers.txt", "r" ); /* input data file */

I am a very fresh c programme user, and need to fscanf data to arrays. Somehow it just doesn't gets recorded, wonder what is wrong with my code?
When I printf the array it always ends up with random numbers. Below is my programme which is just designed to read a doc and print it back out, as well as the text doc it is designed to read.

Example radix sort function to sort an array of 64 bit unsigned integers. To allow for variable bin sizes, the array is scanned one time to create a matrix of 8 histograms of 256 counts each, corresponding to the number of instances of each possible 8 bit value in the 8 bytes of each integer, and the histograms are then converted into indices by summing the histograms counts. Then a radix sort is performed using the matrix of indices, post incrementing each index as it is used.
Code:
typedef unsigned long long UI64;
typedef unsigned long long *PUI64;
PUI64 RadixSort(PUI64 pData, PUI64 pTemp, size_t count) {
size_t mIndex[8][256] = {0};
/* index matrix */
PUI64 pDst, pSrc, pTmp;
size_t i,j,m,n;
UI64 u;

I was running some Monte carlo simulations and I was having some trouble passing my Normal-Random-Generating object as a parameter to the simulator.
I created a class called BoxMull which used the Box-Muller algo to generate Normal randoms and I based the Box-Muller algo on random numbers generated by the Mersenne-twister engine.
I am getting an error while compiling.
