Decode Status Register into Human-Readable Flags

Code

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

const char *flag_names[8] = {
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"
};

void decode_status(uint8_t status_reg) {
    // Your logic here
    /*
    if (status_reg & (1 << 0)) printf("Power On
");
    if (status_reg & (1 << 1)) printf("Error
");
    if (status_reg & (1 << 2)) printf("Tx Ready
");
    if (status_reg & (1 << 3)) printf("Rx Ready
");
    if (status_reg & (1 << 4)) printf("Overheat
");
    if (status_reg & (1 << 5)) printf("Undervoltage
");
    if (status_reg & (1 << 6)) printf("Timeout
");
    if (status_reg & (1 << 7)) printf("Reserved
");
    */
    for (int i = 0; i < 8; i++) {
        if ((status_reg & (1 << i))) {
            printf("%s\n", flag_names[i]);
        }
    }

}

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