indexed bubble sort funktion

allesammen,

Jeg skal aendre nedenstaaende prgram og lave en indexed bubble sort funktion.
Det skal aendres ved hjaelp af foelgende data:

void indexedbubblesort (float valuearray [], int indexarray[], int n)
valuearray - indeholder input til array
index- indeholder indices til value array
int n- indeholder antal elementer i arrays

Er der en der kan se hvordan de kan aendres og opfylde ovenstaaende betingelser?
Paa forhaand tak!

#include "iostream.h"
#include "time.h"
#include "stdlib.h"
#include "stdio.h"

// function prototypes
void bubbleSort(float valuearray[], int n) ;

void main()
{
// randomize by time
srand( (unsigned)time( NULL ) );

// vars used
int i, n = 10;
float *array;

// alloc vars
array = new float[n];

// test alloc
if( array == 0 )
{
cout << "alloc failed" << endl;
return;
}

// generate number between 0.0 and 100.0
for( i = 0; i<n; i++ )
{
array = (rand()%1000)*0.1f;
}

// cout unsorted
cout << "Unsorted numbers:" << endl<< endl;
for( i = 0; i<n; i++ )
{
cout << array << " ";
}
//function call
bubbleSort(array, n);

// cout sorted
cout <<endl<<endl<< "Sorted numbers:" <<endl<<endl;
for( i = 0; i<n; i++ )
{
cout << array << " ";
}

cout << endl;
}

void bubbleSort(float valuearray[], int n)
{
bool exchanges;
do {
exchanges = false; // assume no exchanges
for (int i=0; i<n-1; i++)
{
if (valuearray > valuearray[i+1])
{
float temp = valuearray;
valuearray = valuearray[i+1];
valuearray[i+1] = temp;
exchanges = true; // after exchange, must look again
}
}
} while (exchanges);
}
