Decode Status Register into Human-Readable Flags

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


void decode_status(uint8_t status_reg) {
    // Your logic here
    static const char *flag_names[8] = {
        "Power On",      // bit 0
        "Error",         // bit 1
        "Tx Ready",      // bit 2
        "Rx Ready",      // bit 3
        "Overheat",      // bit 4
        "Undervoltage",  // bit 5
        "Timeout",       // bit 6
        "Reserved"       // bit 7
    };

    for(size_t bit = 0; bit < 8; bit++)
    {
        if(status_reg & (1U << bit))
        {
            printf("%s\n",flag_names[bit]);
        }
    }
}

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