ADCChannel Constructor Validation

#include <iostream>
using namespace std;

// Write your ADCChannel class here
class ADCChannel {
private:
    int channel = 0, resolution = 12;
public:
    ADCChannel(int ch, int res){
        if(ch > 15) channel = 15;
        else if(ch < 0) channel = 0;
        else channel = ch;
        
        if((res == 8) || (res == 10) || (res == 12))
            resolution = res;
    }

    void print(){
        cout << "CH=" << channel << " RES=" << resolution;
    }

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

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

    return 0;
}
