Real-Time Traffic Control System with Traffic Lights in C++

#include <iostream>     // Include the input-output stream library
#include <thread>        // Include the thread library for controlling time intervals
#include <chrono>        // Include the chrono library for time manipulation
using namespace std;

// Function to simulate the traffic light control system
void trafficLightControl(int redDuration, int yellowDuration, int greenDuration) {
    while (true) {  // Infinite loop to simulate continuous traffic light cycles
        // Simulate Red Light
        cout << "RED LIGHT - Stop" << endl;
        this_thread::sleep_for(chrono::seconds(redDuration));  // Wait for the specified red light duration

        // Simulate Yellow Light
        cout << "YELLOW LIGHT - Prepare to stop or go" << endl;
        this_thread::sleep_for(chrono::seconds(yellowDuration));  // Wait for the specified yellow light duration

        // Simulate Green Light
        cout << "GREEN LIGHT - Go" << endl;
        this_thread::sleep_for(chrono::seconds(greenDuration));  // Wait for the specified green light duration
    }
}

    int redDuration, yellowDuration, greenDuration;

    // Ask the user to enter the duration for each light color
    cout << "Enter the duration for RED light in seconds: ";
    cin >> redDuration;

    cout << "Enter the duration for YELLOW light in seconds: ";
    cin >> yellowDuration;

    cout << "Enter the duration for GREEN light in seconds: ";
    cin >> greenDuration;

    // Start the traffic light control system with the specified durations
    trafficLightControl(redDuration, yellowDuration, greenDuration);

    return 0;
}

 Output

Enter the duration for RED light in seconds: 5
Enter the duration for YELLOW light in seconds: 2
Enter the duration for GREEN light in seconds: 3
RED LIGHT - Stop
(Yellow light cycle after 5 seconds)
YELLOW LIGHT - Prepare to stop or go
(Green light cycle after 2 seconds)
GREEN LIGHT - Go
(Red light cycle after 3 seconds)
