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 *arr[8]={"Power On","Error","Tx Ready","Rx Ready","Overheat","Undervoltage"
    ,"Timeout","Reserved"};
     for (uint8_t index = 0; index < 8; index++) {
        // Your bit-checking logic is perfect.
        if ((status_reg >> index) & 1) {
            printf("%s\n", arr[index]);
        }
    }
}

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