#include 
#include    // for sleep_for
#include    // for seconds
using namespace std;

class LED {
private:
    string color;
    bool state; // true = ON, false = OFF

public:
    LED(string c) {
        color = c;
        state = false; // initially OFF
    }

    void on() {
        state = true;
        cout << color << " LED is ON" << endl;
    }

    void off() {
        state = false;
        cout << color << " LED is OFF" << endl;
    }

    void blink(int times, int delaySec) {
        for (int i = 0; i < times; i++) {
            on();
            this_thread::sleep_for(chrono::seconds(delaySec));
            off();
            this_thread::sleep_for(chrono::seconds(delaySec));
        }
    }
};

int main() {
    LED led1("Red");

    cout << "Blinking LED..." << endl;
    led1.blink(5, 1); // blink 5 times with 1-second delay

    return 0;
