ADC Config Flags

#include <iostream>
#include <cstdint>
using namespace std;

enum class AdcConfig : uint8_t{
    ChannelEnable = 1,
    InterruptEnable = 2,
    DMAEnable = 4
};

// Implement void printConfig(uint8_t cfg)
void printConfig(uint8_t cfg){
    if(cfg & 1) cout <<"ChannelEnable ";
    if(cfg & 2) cout <<"InterruptEnable ";
    if(cfg & 4) cout <<"DMAEnable";
    if(!(cfg & 7)) cout << "None";
}
int main() {
    int ch, intr, dma;
    cin >> ch >> intr >> dma;

    uint8_t cfg = 0;
    if (ch)   cfg |= static_cast<uint8_t>(AdcConfig::ChannelEnable);
    if (intr) cfg |= static_cast<uint8_t>(AdcConfig::InterruptEnable);
    if (dma)  cfg |= static_cast<uint8_t>(AdcConfig::DMAEnable);

    printConfig(cfg);
    return 0;
