Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    uint8_t res;
    for(uint8_t i =0;i<8;i++)
    {
        res = status_reg & ((0x01)<<i);
        if(res!=0)
        {
            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");
                        break;
            }
        }
    }
}

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