ADCChannel Constructor Validation

#include <iostream>
using namespace std;

// Write your ADCChannel class here
class ADCChannel{
    private:
    int channel;
    int resolution;

    public:
    ADCChannel(int ch, int res) noexcept
    {
        if ( ch < 0)
        {
            channel = 0;
        }
        else if ( ch > 15)
        {
            channel = 15;
        }
        else
        {
            channel = ch;
        }

        if ( res == 8 || res == 10 || res == 12 )
        {
            resolution = res;
        }
        else
        {
            resolution = 12;
        }
    }

    void print() const noexcept
    {
        cout << "CH=" << channel << " RES=" << resolution << endl;
    }
};
int main() {
    int ch, res;
    cin >> ch >> res;

    ADCChannel adc(ch, res);
    adc.print();

    return 0;
}
