C++ Notification System for Integration with Other Programs

Overview

This is a C++ Notification System designed to be integrated into any C++ program. It provides real-time notifications via console messages, log files, or emails. This system can be useful for applications like banking, rentals, and other C++ projects that require alert mechanisms.

Main Features

1. Supports multiple notification methods – Console, log files, and emails (future scope).
2. Easily integrates with any C++ project – Simple function calls enable seamless notifications.
3. Modular design – The system is structured to allow extensions and modifications.

C++ Notification System Code

1. Notification System Implementation

#include <iostream>
#include <fstream>
#include <ctime>
#include <string>

using namespace std;

// Types of notifications
enum NotificationType { CONSOLE, LOGFILE };

// Function for getting current timestamp
string getTimestamp() {
    time_t now = time(0);
    char buffer[80];
    strftime(buffer, sizeof(buffer), "%Y-%m-%d %H:%M:%S", localtime(&now));
    return string(buffer);
}

// Notification System Class
class NotificationSystem {
public:
    static void sendNotification(const string& message, NotificationType type = CONSOLE) {
        string timestampedMessage = "[" + getTimestamp() + "] " + message;

        switch (type) {
            case CONSOLE:
                cout << timestampedMessage << endl;
                break;
            case LOGFILE:
                logToFile(timestampedMessage);
                break;
        }
    }

private:
    static void logToFile(const string& message) {
        ofstream logFile("notifications.log", ios::app);
        if (logFile.is_open()) {
            logFile << message << endl;
            logFile.close();
        } else {
            cerr << "Error: Unable to open log file!" << endl;
        }
    }
};

// Example usage (can be called from another program)
int main() {
    NotificationSystem::sendNotification("New user registered.", CONSOLE);
    NotificationSystem::sendNotification("Transaction failed. Logging error...", LOGFILE);
    return 0;
}

2. Integrating the Notification System into Another C++ Program

To use this notification system in an existing C++ program, follow these steps:

Step 1: Include the Header File

Add the following line to the existing program to include the Notification System:

#include "NotificationSystem.h"

Step 2: Call the sendNotification Function

Invoke the function in the program wherever notifications are required. Example:

NotificationSystem::sendNotification("New transaction detected: $500 withdrawn.", LOGFILE);

Conclusion

This C++ Notification System allows seamless integration with other programs, providing essential notifications through multiple channels. It is lightweight, modular, and can be extended to support additional features like email alerts.
