TCP Echo Client using Sockets

In this TCP Echo Client programming video, we will code a Client which is capable of interfacing with the TCP Echo server created in the previous video. The Client program will connect to the Echo server and send it a user inputted string. The Server will echo back the same string to the Client. The Client now display the same to the user. Please watch this video pair very carefully, as they form the building blocks of most TCP based Client / Server programming.
