Decode Status Register into Human-Readable Flags

Code

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

uint8_t is_bit_set(uint8_t reg,uint8_t pos){
    if(reg&(1<<pos)){
        return 1;
    }
    return 0;
}

const char * flag[]={
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"
};

void decode_status(uint8_t status_reg) {
    // Your logic here
    for(uint8_t i=0;i<8;i++){
        if(is_bit_set(status_reg, i)){
            printf("%s\n", *(flag+i));
        }
    }
}

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