Online Shopping System

Our project is an online shopping system which utilizes the abilities of C++ language while abiding by the rules and regulations of OOP. The project is a console application which primarily consists of two pieces of code:

1. The networking layer.
2. The management layer.

Dependencies

The project has used the windows api of threading and socket programming - Winsock2 library. Therefore, the project can only be compiled to windows machines that support this library. Also, make sure to link the object file with winsock modules.

The networking layer also uses the local host 127.0.0.1 ip as default. You can change it in the Server.h

Networking layer

The networking layer consists of those classes and functions which are responsible for establishing a connection between a client and the remote sever.

Technology

The networking is carried out with the help of Winsock (2.2) programming - windows APIs of socket programming.

Classes

The Server - which uses the Thread class - and Client class.

Usage

The networking layer is independent of the management layer; it can used in any C++ program. You can download the following files and use them in your own project.

• Server: Server.h - Server.cpp and Thread.h - Thread.cpp
• Client: Client.h - Client.cpp

You may utilize the networking functions like:

Server:

#include "Server.h"

void worker(Thread& server)
{
    // code to deal with client
    server.Rec(buffer);     // receive a msg from client
    server.Send(msg);       // send a msg to client
    server.endServer();     // close the server
}

int main()
{
    Server server(worker);
    if (server.start())
        server.run();

    return 0;
}

Client:

#include "Client.h"

int main()
{
    Client client;
    if (client.start())
    {
        // code to deal with server
        client.Rec(buffer);     // receive a msg from server
        client.Send(msg);       // send a msg to server
    }
        
    return 0;
}

Working

Management layer

This layer uses the networking layer to implement a networked shopping app.
