Decode Status Register into Human-Readable Flags

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

#define BIT(n) ((uint8_t)(1u << (n)))

const char *flags[8] = {
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"
};
void decode_status(uint8_t status_reg) {
    // Your logic here
    for (int i = 0; i < 8; ++i) {
    if (status_reg & BIT(i)) {
        printf("%s\n", flags[i]);
    }
    }
}

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