Decode Status Register into Human-Readable Flags

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

void decode_status(uint8_t status_reg) {
    // Your logic here

    char* arr[8] = {"Power On","Error","Tx Ready","Rx Ready","Overheat","Undervoltage",
    "Timeout","Reserved"};
    for(int i=0 ; i<8 ; i++)
    {
        if(status_reg & (1<<i))
        {
            printf(arr[i]);
            printf("\n");
        }
    }
}

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