Find Top 3 Largest Values in an Array

Code

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

void find_top_3(uint8_t *arr, uint8_t n) {
    for(int i = 0; i < n; i++){
        for(int j = i + 1; j < n; j++){
            if(*(arr + j) > *(arr + i)) {
                uint8_t temp = *(arr+i);
                *(arr + i) = *(arr + j);
                *(arr + j) = temp;
            }
        }
    }
    int k = 3;
    if(n < 3) k = n;
    // int k = 3 % n;
    for(int i = 0; i < k; i++){
        printf("%d ", *(arr + i));
    }

}

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

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

    find_top_3(arr, n);
    return 0;
}
