Decode Status Register into Human-Readable Flags

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

void decode_status(uint8_t status_reg) {
    
   const char *flagnames[] = {
        "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(int i = 0 ; i < 8 ; i++){
    if((status_reg >> i) & 1){
        printf("%s\n", flagnames[i]);
    }
   }
}

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