PWM Constructor Modes

#include <iostream>
using namespace std;

// Write your PWMController class here
class PWMController{
    int frequency;
    int duty;
    bool enabled;
    public:
    PWMController(int freq) : frequency(freq),duty(0),enabled(false){}
    PWMController(int freq,int dutyCycle) : frequency(freq),enabled(true){
        duty=dutyCycle<0 ? 0 : dutyCycle>100 ? 100 : dutyCycle;
    }
    void setDuty(int d){
        duty=d<0 ? 0 : d>100 ? 100 : d;
    }
    void disable(){
        enabled=false;
    }
    void print(){
        printf("F=%d D=%d EN=%d",frequency,duty,enabled);
    }
};
int main() {
    int mode;
    cin >> mode;

    PWMController pwm(0); // temporary placeholder

    if (mode == 1) {
        int f;
        cin >> f;
        pwm = PWMController(f);
    }
    else {
        int f, d;
        cin >> f >> d;
        pwm = PWMController(f, d);
    }

    int x;
    cin >> x;

    if (x == -1)
        pwm.disable();
    else
        pwm.setDuty(x);

    pwm.print();
    return 0;
}
