Find Minimum and Maximum in an Array

Code

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

void find_min_max(uint8_t *arr, uint8_t n, uint8_t *min, uint8_t *max) {
    // Your logic here
    uint8_t *a = arr;
    uint8_t _min = 0;
    uint8_t _max = 0;
    int index_max = -1;
    int index_min = -1;

    while(a <= (arr+n-1))
    {
        if(index_min == -1)
            _min = *a;

        if(index_max == -1)
            _max = *a;

        uint8_t *b = arr ; 
        bool test_min = 1;
        bool test_max = 1;

        while(b <= (arr+n-1))
        {
            test_max &= (_max >= *b)? 1:0;
            test_min &= (_min <= *b)? 1:0;
            b+=1;
        }

        if(test_max & (index_max == -1))
            index_max = a - arr; 

        if(test_min & (index_min == -1))
            index_min = a - arr;

        a+=1;
    }

    *min = *(arr+index_min);
    *max = *(arr+index_max);
}

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

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

    uint8_t min_val, max_val;
    find_min_max(arr, n, &min_val, &max_val);

    printf("%hhu %hhu", min_val, max_val);
    return 0;
