Decode Status Register into Human-Readable Flags

Code

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

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

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