Decode Status Register into Human-Readable Flags

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

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

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