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",      // flags[0] → bit 0
        "Error",         // flags[1] → bit 1
        "Tx Ready",      // flags[2] → bit 2
        "Rx Ready",      // flags[3] → bit 3
        "Overheat",      // flags[4] → bit 4
        "Undervoltage",  // flags[5] → bit 5
        "Timeout",       // flags[6] → bit 6
        "Reserved"       // flags[7] → bit 7
    };
    
    for (int 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;
}
