Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    int bit;
    for(int i=1;i<=8;i++)
    {
        if(status_reg<(1<<i))
        {
            bit = i;
            break;
        }
    }
    for(int j=0;j<bit;j++)
    {
        if(status_reg & (1<<j))
        {
            switch(j)
            {
                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;
            }
        }
    }

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