Decode Status Register into Human-Readable Flags

Code

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


void decode_status(uint8_t status_reg) {

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

    // Your logic here
    for (int i = 0; i < 8; i++) {
        if ((status_reg & 1) == 1) {
            printf("%s\n", str[i]);
        }
        status_reg = status_reg >> 1;
    }
}

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