PWM Register Access Control

#include <iostream>

class PWMDriver {
private:
    // TODO: This member is exposed. Encapsulate it.
    // TODO: Ensure valid range [0, 100].
    int ccr_reg;
public:

    PWMDriver() : ccr_reg(0) {}

    void set_ccr_reg(int value)
    {
        if ( value > 100) ccr_reg = 100;
        else if ( value < 0) ccr_reg = 0;
        else ccr_reg = value;
    }

    int get_ccr_reg() const
    {
        return ccr_reg;
    }
    
    // TODO: Add getter if necessary for printing
};

int main() {
    int N;
    if (!(std::cin >> N)) return 0;

    PWMDriver driver;

    for (int i = 0; i < N; ++i) {
        int val;
        std::cin >> val;

        // TODO: Refactor this access to use a safe setter method
        driver.set_ccr_reg(val);

        // Output current state
        std::cout << "CCR: " << driver.get_ccr_reg() << std::endl;
    }

    return 0;
