Decode Status Register into Human-Readable Flags

Code

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

const char *arr[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 & (1 << i)) {
            printf("%s\n", arr[i]);
        }
    }
}

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