Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
   const char* flags[] = {
        "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 (uint8_t i = 0; i < 8; i++)
    {
        if (status_reg & (1 << i))
        {
            printf("%s\n", flags[i]);
        }
    }
}

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