Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    char* reg_names [8] = {"Power On",
                         "Error",
                         "Tx Ready",
                         "Rx Ready",
                         "Overheat",
                         "Undervoltage",
                         "Timeout",
                         "Reserved"};

    for(int i=0;i<8;i++){
        if(status_reg >> i & 1U){
            printf("%s\n",reg_names[i]);
        }
    }
}

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