Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    const char *MEANING[8] = {
        "Power On",
        "Error",
        "Tx Ready",
        "Rx Ready",
        "Overheat",
        "Undervoltage",
        "Timeout",
        "Reserved"
    };
    for (int16_t i = 0; i < 8; i++) {
        if ((1 << i) & status_reg) {
            printf("%s\n", MEANING[i]);
        }
    }
}

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