C++ :: Sort Ascending Random Numbers - Vectors
Oct 21, 2013
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.

I am trying to write a program which will sort an array of numbers into ascending order, here is my code
#include<iostream>
#include<cmath>
using namespace std;
int main(){
int array[]={1, 5, 17, 3, 75, 4, 4, 23, 5, 12, 34, 34, 805, 345, 435, 234, 6, 47, 4, 9, 0, 56, 32, 78};
[Code] .....
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.

I can't compile this code as I am at work and the computers are security protected, So i''l have to wait until i get home to test this, but I am pretty sure I am wrong. The problem is I have to create two vectors with 10 elements and input random numbers into it, then pick one of the elements of the second vector at random and append it to an element from the first vector at random. This has to be done 10 times and the I am assuming i have to print the 10 results. This is what I have:
#include <cstdlib>
#include <ctime>
#include <iostream>
using namespace std;
int main() {
vector<int> random (10);
[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 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)

I have a vector which contains vectors containing 7 integers each. I'd like to sort these vectors based on the value of the first integer (int IOT), in ascending order. I know this type of question can be found everywhere, but I'm lost as to why this doesn't compile.
#include <fstream>
#include <iostream>
#include <vector>
#include <string>
#include <algorithm>
#include <stdio.h>
#include <math.h>
#include <windows.h>

int IOT; // Incoming Order Time

I am having trouble sorting out a list of names in c. I have code for sorting the names, but when I go to print them out they still are in the same order as they were at the beginning so something isnt right. So the function that I need is the sort_data function.
Code:
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#define MAX_STRING_LEN 25
void insert_data(char **strings, const char* filename, int size);
void allocate(char ***strings, int size);
[Code] ....
The list that I am reading in is as follows:
matt
susan
mark
david
aden
phil
erik
john
caden
mycah
So I need to get this list in alphabetical order, but when I run my code and print out this list after I run the sort function, they are still in this order.

We've only covered up to Functions and how to use reference variables inside the function parameter.
One of the hw problem that was assigned was to write a void function that takes three parameters( num1, num2, num3) by reference and sorts their values into ascending order, so that num1 has the lowest, num2 the middle value, and num3 the highest value. For example, if user enters: 14, -4, 8, then the output should look like this:
-4
8
14
I've completed the program with a bunch of if/ else if statements but I was wondering if there was a more efficient way to sort the numbers. Bear in mind, we've only covered materials up to functions so I can't use any other new techniques that we haven't cover yet. Here is my code:
// This program will take three int parameters by reference and sorts their value into ascending order
//so that num1 has the lowest value, num2 has the middle value, and num3 has the highest value
#include <iostream>
using namespace std;
// declare function with reference parameter that with sort numbers
void sortNum(int &, int &, int &);
int main ()
{

I have to put these numbers in ascending and descending order . The interesting point of the function is that sortMe does 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. I'm not sure why the function is working, even though I called it in main.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void sortMe(int array[], int sortedIndexes[], int size, char mode);
char option;
const int SIZE = 5;

I am trying to print the prime numbers, so i put the numbers into the vector and then erase the non prime numbers. if i comment the break statement i get runtime error saying out of bound, but if i don't comment it out it prints the primes but it also prints the multiples of 3.
void Eratos( int length, vector< int > &v ) {
int i;
for (i=0; i<length; ++i) {
v.push_back(i);
