Decode Status Register into Human-Readable Flags

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

const char *array[8] = {
    "Power On\n",
    "Error\n",
    "Tx Ready\n",
    "Rx Ready\n",
    "Overheat\n",
    "Undervoltage\n",
    "Timeout\n",
    "Reserved\n"
};

void decode_status(uint8_t status_reg)
{
    for (int i = 0; i < 8; i++)
    {
        if (status_reg & (1U << i))
        {
            printf("%s", array[i]);
        }
    }
}

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

    decode_status(reg);

    return 0;
}
