Sort an Array in Descending Order

Code

#include <stdio.h>
#include <stdint.h>

void bubble_sort_desc(uint8_t *arr, uint8_t n) {
    // Your logic here
    for (int i = n - 1; i > 0; i--){
        for (int j = n -1; j > 0; j--){
            uint8_t *a = arr +n - j;
            uint8_t *b = arr + n -j - 1;
            if ( *a > *b){
                uint8_t temp = *b;
                *b = *a;
                *a = temp;
            }
        }
    }
}

int main() {
    uint8_t n;
    scanf("%hhu", &n);
    uint8_t arr[100];

    for (uint8_t i = 0; i < n; i++) {
        scanf("%hhu", &arr[i]);
    }

    bubble_sort_desc(arr, n);

    for (uint8_t i = 0; i < n; i++) {
        printf("%hhu", arr[i]);
        if(i < n-1){
            printf(" ");
        }
    }

    return 0;
}
