Hi i Am A Newbie In This Website So Please Go Easy on Me. I Have Baisc Knowledge of C++
And I Do Projects on A Daily Basis, But I Have Never Tried Anything Related To Networking .So I am Asking How Can I Make A Chat Program With 2 PC And Assigned IP For Them . :idea:
Paradon For My Bad English :)
Since, your c++ knowledge is basic and the program that you are trying to build is very complex, you should only do simpler programs instead of it.
However i am giving you the source code of a program that uses PC to PC Communication via RS232 port. Chat with only 3-wire connection.
This program is tested with Turbo C++ editor Version 3.0.

}Compile it using Turbo c++ compiler v3.0
Best of luck!
Hey The Code You Have Given is Written In C Not In C++
And one More thing Please Explain Some Main Points of The Code
Anyway Thanks
This program is written in C++ not C.
Do compile it with TURBO C++ compiler v3.0
This program is written in C++ not C.
At a glance, I'd call that code C, and bet that it compiles just fine as C. It would also compile as C++, but if you're using a strict C-compatible subset of C++, quibbling over the code being C++ is kind of stupid.
Do compile it with TURBO C++ compiler v3.0
This is a different problem entirely. As an example posted in 2011, code using a compiler and techniques from 1991 can only be described as a waste of everyone's time.
