Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    const char *flag[]={"Power On","Error","Tx Ready","Rx Ready","Overheat","Undervoltage","Timeout","Reserved"};
    unsigned int i=0;
    for(i=0;i<8;i++){
        if(status_reg & (1<<i)){
          printf("%s",flag[i]);
          printf("\n");
        }
    }
}

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