I would like to know the simplest and most effective way to open and write data to a socket in the C programming language for network programming.

When you are closing the client using ctrl + c , OS will stop the client process and close all the sockets opened by it.
The steps involved in establishing a TCP socket on the server side are as follows: Create a socket with the socket() function; Bind the socket to an address using the bind() function; Listen for connections with the listen() function; Accept a connection with the accept() function system call.
You're right, using sockets in C has a difficult syntax. Later languages like Java and Python make it a snap by comparison. The best tutorial I've found for doing socket programming in C is Beej's Guide to Network Programming. I recommend you start at the beginning to get a good overview, but if you just need to get some code working now, you can skip ahead to the section titled Client-Server Background.
Good luck!

You don't mention what platform you are on, but a copy of Unix Network Programming by Stevens would be a good addition to your bookshelf. Most operating systems implement Berkley Sockets using socket, bind, connect, etc.
