Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    for (uint8_t i=0; i<8; 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;
}
