Overview

This project includes two C programs—a TCP server and client—that exchange text and return its reversal over a network connection.

Compilation

Compile on any Linux system (e.g., Jason/Volta) or WSL:

gcc server.c -o server
gcc client.c -o client

Usage

Open two terminals (or MobaXterm splits/tabs):

1. Start the server on port 5000:

   ./server 5000

   Expected output:

   Server listening on port 5000
   

2. Run the client against the server:

   ./client 127.0.0.1 5000

Interactive Mode

• Enter your message (e.g. Hello World) and press Enter.
• Press Ctrl+D to signal end-of-input.
• The client displays the reversed text and exits:

  dlroW olleH
  Connection closed
  

Non‑interactive Mode

Send data via a shell pipe:

echo "Hello World" | ./client 127.0.0.1 5000

Prints reversed text immediately.

Example

Server terminal:

$ ./server 5000
Server listening on port 5000
Client connected
Client disconnected

Client terminal:

$ echo "Hello World" | ./client 127.0.0.1 5000
dlroW olleH
Connection closed

Notes

• Uses standard glibc—no external libraries needed.
• Ensure your port (e.g., 5000) is free.
• To connect across hosts, replace 127.0.0.1 with the server’s IP address.
