[C++] Code to let people connect to computer

[I-Am-No-Fool]

well, I am not very good at C++ and I need help making a code that will let people connect to the program and the computer running the program via the port 4007. I have the first bit of code which only uncludes writing and clearing the screen.

#include <conio.h>
#include <iostream>
using namespace std;

int main()
{
    cout << "Welcome to the Server launcher\n"; 
    cout << "\nHit any key to continue\n";
    getch();
    cout << "\nLoading... Please Wait... ";
    long int i;
    for(i = 0; i < 100000000; i++);
    cout << "Done!\n\n";
    cout << "Hit any key to continue\n";
    getch();
    return 0;
}

So after the getch in red I'm hoping to put a connection code.

Thanks
Rob

Take a look at ENet, it's what I have been using for a bit some months ago when I needed connections.

It's really neat when you got it working xD

[I-Am-No-Fool]

Thanks for that :D

EDIT: one problem, The client is already coded up in java so I cant use the enet client code which I'm sure is needed

[FragFrog]

That depends hugely on what you wish to do, and how. I somewhat fail to see why you would want to put a resource hogging for loop in there as well (since it's a server - so you're the only one that sees it - so you want to keep yourself busy?), but that is another matter I deem.

In my experience Daevius makes a very valid point, though possibly unintentionally: "when you got it working". This is unfortunately a somewhat typical sentiment when C++ is concerned. Do you really want to write this in C++? Creating a socket listener in JAVA is as easy as saying socket = new ServerSocket(port); socket.accept(); - a much more friendly language for the new developer

Seriously, did you even tried Google?
Just one thing, if your not good at C++, try to learn.

[zarut]

or just use C# its still easier :/ http://www.java2s.com/Code/CSharp/Ne...eTcpServer.htm
anyway even the client is coded in java it should not matter since you code the server act just like normal server so it should work in each language / socket aslong it takes connections from right port

[Daevius]

or just use C# its still easier :/ http://www.java2s.com/Code/CSharp/Ne...eTcpServer.htm

How is C# easier if you know C++ and no C#? This code looks almost identical to C++ code, just some syntax changes...please clarify how C# would be "easier" here?

intellisense and the error shit you can see real time helps alot which makes it easier to code

What an incredible argument you have there, I'm amazed o_O

So easier for people who find trouble debugging code?

I'll buy that. Though debugging is a key part to the process of learning programming. That's what makes us learn to do things the right way, the first time. Of course everyone makes mistakes, but by training yourself time-after-time to write good code, you start to resent people who live by the C# bells & whistles.

By learning how to debug and write code more proficiently, you start to solve more and more problems beforehand just knowing their going to come up. That makes the programmer more sharp and proficient while coding.

Just doing it in C# because it's easier is fine and dandy, the program works, right? Well I personally would rather live in a cross-compatible environment. I write code and learn to debug. I even turn off error messages in PHP and figure out the errors the hard way.. Then when I'm all done I'll see how many warning messages I failed to prevent. It's like a fun little game for me.

And you know what, I hardly ever code an error anymore.

We're human, I feel we should take advantage of it.

And I know Daevius can write debugged code in C++ in the same amount of time you code it in C#. Especially if the rules state to start with a blank desktop. Then notepad++ will open waaayyy faster than visual C#. Lol idk.. just rambling now

or just use C# its still easier :/ http://www.java2s.com/Code/CSharp/Ne...eTcpServer.htm

Code samples / tutorials like that is what makes people incapable of programming in C++.

That's just like.. really.... really bad.
