Decode Status Register into Human-Readable Flags

Code

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

void print(uint8_t bit_pos)
{
    switch(bit_pos)
    {
        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;
    }
}
void decode_status(uint8_t status_reg) {
    // Your logic here
  
    for(uint8_t i=0;i<8;i++)
    {
       if((status_reg>>i)&1)
       {
        print(i);
       }
    }
}

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