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
    uint8_t *a = arr;
    uint8_t pass = false;
    uint8_t tmp = 0;
    while(pass == false)
    {
        a = arr;
        bool bit_test = 1;
        while(a <= (arr+n-2))
        {
            if((*a < *(a+1)) & (*a != *(a+1)))
            {
                tmp = *a;
                *a  = *(a+1);
                *(a+1) = tmp;
                bit_test = false;
            }
            a++;
        }

        pass = bit_test;
        
    }
}

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;
}
