Decode Status Register into Human-Readable Flags

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

static inline uint8_t check_bit(uint8_t reg, uint8_t b)
{
    return reg & (1U << b);
}

void decode_status(uint8_t status_reg)
{
    // Your logic here
    for (uint8_t i = 0; i < 8; i++)
    {

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

        if (check_bit(status_reg, i))
        {
            printf("%s\n", status_str[i]);
        }
    }
}

int main()
{
    uint8_t reg;
    scanf("%hhu", &reg);
    decode_status(reg);
    return 0;
}
