Write a program in C to sort element of array in descending order

#include <stdio.h>

void swap(int *a, int *b) {
    int temp = *a;
    *a = *b;
    *b = temp;
}

void bubbleSort(int arr[], int n) {
    int i, j;
    for (i = 0; i < n-1; i++) {
        for (j = 0; j < n-i-1; j++) {
            if (arr[j] < arr[j+1]) {
                swap(&arr[j], &arr[j+1]);
            }
        }
    }
}

int main() {
    int arr[] = {64, 34, 25, 12, 22, 11, 90};
    int n = sizeof(arr)/sizeof(arr[0]);
    bubbleSort(arr, n);
    printf("Sorted array in descending order: \n");
    for (int i=0; i < n; i++)
        printf("%d ", arr[i]);
    return 0;
}
