Decode Status Register into Human-Readable Flags

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

const char *arr[8] = {"Power On", "Error", "Tx Ready", "Rx Ready", "Overheat", "Undervoltage", "Timeout", "Reserved"};
void decode_status(uint8_t status_reg) {
    int pos = 0;
    while(status_reg > 0)
    {
        if(status_reg & 1)
        {
            printf("%s\n", arr[pos]);
        }
        pos++;
        status_reg >>= 1;
    }
}

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