Decode Status Register into Human-Readable Flags

Code

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

const char *data[] = { "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 < sizeof(status_reg)*8; i++)
    {
       if(status_reg & (1<<i))
       {
            printf("%s\n", data[i]);
       }
    }
}

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