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* flag_names[] = {
        "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
    };
    
    // Check each bit from LSB to MSB
    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;
}
