Decode Status Register into Human-Readable Flags

Code

#include <stdio.h>
#include <stdint.h>
const char *flags[8] = {
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"
};
void decode_status(uint8_t reg) {
    int i=0;
    while (i<8){
        if((reg >> i)&1){
            printf("%s\n",flags[i]);
        }
        i++;
    }
}

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