Winsock Server Client Example

Good morning, As I work in the uni, they have sent us to do a program with a server and a client. But for this we have been told that first we have to make an example of server and client work. They have given us the example like this, with these 2 codes.

Server: link

Client: link

What I have done has been to open a project and I have put each code (the one of the client and the server) in a file: server.cpp and client.cpp

And after fixing a problem with the headers I got stuck with these 2 errors:

Severity Code Description Project File Line Suppression State Error LNK2005 _main already defined in client.obj BAAER2 D: \ DDocuments \ BAAER2 \ BAAER2 \ BAAER2 \ server.obj 1

and

Severity Code Description Project File Line Suppression State Error LNK1169 one or more multiply defined symbols found BAAER2 D: \ DDocuments \ BAAER2 \ BAAER2 \ Debug \ BAAER2.exe 1

The first one I think it has is that I have 2 files with main but I'm not sure how to fix it.

PS: The teacher said that you had to add or pass as argument localhost (127.0.0.1), with right click properties ... but I do not remember much more, do you also know this?

Create two different projects, one called, client and the other server. Put each of the sources in one of these different projects. Both projects must link the ws_32.lib library that provides the winsock2 methods.

Then you compile the projects and run the server first.

Finally, you run the client from the command line like this: (you must find where the compiler left the .exe file)

C:\Path\al\cliente> cliente.exe 127.0.0.1

With that it should work.
