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 i =0;
        for(i =0; i<=7; i++)
        {
            if((status_reg>>i)&1)
            {
               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;
               }
            }
        }
       
    }

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