Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t reg) {
    // Your logic here
    switch(0)
    {
        case 0 : if(reg & 1)
                printf("Power On\n");
        case 1 : if((reg >> 1) & 1)
                printf("Error\n");
        case 2 : if((reg >> 2) & 1)
                printf("Tx Ready\n");
        case 3 : if((reg >> 3) & 1)
                printf("Rx Ready\n");
        case 4 : if((reg >> 4) & 1)
                printf("Overheat\n");
        case 5 : if((reg >> 5) & 1)
                printf("Undervoltage\n");
        case 6 : if((reg >> 6) & 1)
                printf("Timeout\n");
        case 7 : if((reg >> 7) & 1)
                printf("Reserved\n");
    }
}

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