PWM Register Access Control

#include <iostream>
class PWMDriver {
private:
    int ccr_reg;  // Encapsulated register

public:
    PWMDriver() : ccr_reg(0) {}

    // Safe setter with saturation logic
    void setCCR(int val) {
        if (val > 100) {
            ccr_reg = 100;
        } else if (val < 0) {
            ccr_reg = 0;
        } else {
            ccr_reg = val;
        }
    }

    // Getter for read-only access
    int getCCR() const {
        return ccr_reg;
    }
};

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

    PWMDriver driver;

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

        driver.setCCR(val);

        std::cout << "CCR: " << driver.getCCR() << std::endl;
    }

    return 0;
}
