Regarding a simple TCP based echo server using Sockets API?

You shouldn't call accept within the loop on the server. Move the accept before the for loop on the server and it should work how you expect.

Your code is doing precisely what you asked it to do. You told it to accept a connection, receive some data from that connection, send that data back to the connection, then accept another connection. That's what it's doing.

I suspect you want to move the accept call outside the for loop.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
