Sort an Array in Descending Order

Code

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

void bubble_sort_desc(uint8_t *a, uint8_t n) 
{
    char flag=1;
    for(int i=1;i<n && flag;i++)
    {
        flag=0;
        for(int j=0;j<n-i;j++) //if the array is already sorted, flag will be zero and it will not enter inner loop for next iteration.
        {
            if(a[j]<a[j+1])
            {
                int temp=a[j];
                a[j]=a[j+1];
                a[j+1]=temp;
                flag=1;
            }
        }
    }
}

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;
}
