ADCChannel Constructor Validation

#include <iostream>
using namespace std;

class ADCChannel{
    private:
        int channel;
        int resolution;
    
    public:
        ADCChannel(int ch, int res){
            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(){
            cout << "CH=" << channel << " RES=" << resolution;

        }
};


int main() {
    int ch, res;
    cin >> ch >> res;

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

    return 0;
