Need to modify my quicksort to descending order!!!

[pichi20]

Hey, I'd appreciate if someone would help me modify this code so the descending order can be displayed on the screen , here it is....

#include <iostream>   // ostream
#include <vector>

#define SIZE 10

using namespace std;


int partition(vector<long unsigned int> & a, int start, int end) {
  unsigned int pivot = a[start];
  unsigned int from_left = start+1;
  unsigned int from_right = end;
  unsigned int tmp;

while (from_left != from_right) {
    if (a[from_left]  <= pivot) from_left++;
    else {
      while (( from_left != from_right)  && (pivot < a[from_right])) from_right--;
      
      tmp =  a[from_right];
      a[from_right] = a[from_left];
      a[from_left] = tmp;
    }
  }
  
  if (a[from_left]>pivot) from_left--;
  a[start] = a[from_left];
  a[from_left] = pivot;

  return (from_left);
}




void quickSort(vector <long unsigned int> & a, int p, int r) {
  if (p < r) {
    int q = partition(a, p, r);
    quickSort(a, p, q - 1);
    quickSort(a, q + 1, r);
  }
}

int main() {  
	int a[SIZE] = {23,43,54,56,77,43,24,97,34,10};

	vector <long unsigned int> V (a,a+SIZE);


  quickSort(V, 0, SIZE-1);

  for( long unsigned int i = 0; i < SIZE; i++){
	  cout<<V[i]<<endl;
 
 
  }
 return 0;
}

change the for loop inside main to this :
for( long unsigned int i = SIZE-1; i > 0; i--)

thank uu, sorry for not being that specific. That's what i tried but the professor didn't accept that because he wants the function to do it
