Decode Status Register into Human-Readable Flags

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

void decode_status(uint8_t status_reg) {
    unsigned char i;
    char *a[] = {"Power On","Error","Tx Ready","Rx Ready","Overheat","Undervoltage","Timeout","Reserved"};
    for(i = 0;i<=7;i++){
        if(status_reg & 0x01){
            printf("%s\n",a[i]);
        }
        status_reg = status_reg>>1;
    }
}

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