Decode Status Register into Human-Readable Flags

Code

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

const char *bit2flag[] = {
    "Power On",
    "Error",
        "Tx Ready",
    "Rx Ready",
        "Overheat",
    "Undervoltage",
        "Timeout",
    "Reserved",
};
void decode_status(uint8_t status_reg) {
    // Your logic here
    for(int i = 0 ; i < 8 ; i++){
        if( (status_reg >> i) & 1){
            printf("%s\n",bit2flag[i]);
        }
    }
}

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