Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
   for(int i=0; i<8; i++){
    if((status_reg&(1<<i))!=0){
    if(i==0){
    printf("%s\n","Power On");
    }
    else if(i==1){
        printf("%s\n","Error");
    }
     else if(i==2){
        printf("%s\n","Tx Ready");
    }
     else if(i==3){
        printf("%s\n","Rx Ready");
    }
     else if(i==4){
        printf("%s\n","Overheat");
    }
     else if(i==5){
        printf("%s\n","Undervoltage");
    }
     else if(i==6){
        printf("%s\n","Timeout");
    }
    else {
        printf("%s\n","Reserved");
    }
   }
}
}

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