ADCChannel Constructor Validation

#include <iostream>
using namespace std;

// Write your ADCChannel class here
class ADCChannel{
    int channel,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;
}
