# TCP Group Chat Application
A multi-threaded TCP socket-based chat server and client implementation using POSIX threads and socket APIs in C, supporting concurrent users with real-time message broadcasting through a centralized server in a command-line interface.
## Features
- Multi-client messaging support (up to 10 concurrent connections)
- Real-time message broadcasting through TCP sockets
- Thread-per-client architecture
- Named user identification
- Clean disconnection handling
- IPv4 network communication
## Technical Implementation
- POSIX TCP/IPv4 sockets for reliable network communication
- pthread library for handling concurrent connections
- Server-client architecture with centralized message broadcasting
- 1024 byte message buffer size
- Local network communication (default port: 2000)
- Dynamic memory allocation for client handling
- Thread detachment for automatic resource cleanup
## Requirements
- GCC compiler
- POSIX-compliant system (Linux/Unix)
- pthread library
## Building the Application
1. Ensure all required files are present:
- `socket_server.c`
- `socket_client.c`
- `socket_util.c`
- `socket_util.h`
- `Makefile`
2. Compile:
```bash
make
```
3. To remove the executables and object files after use:
```bash
make clean
```
## Usage
### Start the Server
```bash
./socket_server.exe
```
### Connect as a Client
```bash
./sockt_client.exe
```
1. Enter your name when prompted
2. Type messages and press Enter to send
3. View incoming messages from other users automatically
4. Type 'exit' to disconnect
## Notes
- Server must be running before clients can connect
- Messages follow format: "username: message"
- Server displays all chat activity
