Decode Status Register into Human-Readable Flags

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    char str[8][15]={"Power On",
                    "Error",
                    "Tx Ready",
                    "Rx Ready",
                    "Overheat",
                    "Undervoltage",
                    "Timeout",
                    "Reserved"};
    uint8_t arr[7]={0};
    uint8_t i = 0;
    uint8_t du = 0;
    while(status_reg / 2 != 0)
    {
        du = status_reg % 2;
        status_reg = status_reg / 2 ;
        arr[i] = du ;
        i++;
    }
    arr[i++] = 1;

    for(uint8_t j = 0 ; j < 8; j++)
    {
        if(arr[j] == 1)
        {
            printf("%s\n",str[j]);
        }
    }
}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    decode_status(reg);
