Decode Status Register into Human-Readable Flags

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

void decode_status(uint8_t status_reg) {
   //13= 0000 1101
   int mask=1;
   for(int i=0;i<8;i++)
   {
        if(status_reg&mask<<i) // 0000 1101 & 0000 0001= 0000 0001
        {
        switch(i)
        {
            case 0:printf("Power On\n");break;
            case 1:printf("Error\n");break;
            case 2:printf("Tx Ready\n");break;
            case 3:printf("Rx Ready\n");break;
            case 4:printf("Overheat\n");break;
            case 5:printf("Undervoltage\n");break;
            case 6:printf("Timeout\n");break;
            case 7:printf("Reserved\n");break;
            default:break;
        }
        mask=1;
        }
   }
}

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