# 🌐 Computer Networks Laboratory (CS39003) 🌐
Welcome to the **Computer Networks Laboratory** repository! This repository houses all the practical exercises, assignments, and projects completed as part of the Computer Networks course (**CS30003**).
## 🌟 Introduction
This repository contains the code and documentation for the laboratory sessions of the **Computer Networks** course. Each lab session focuses on different aspects of computer networking, including network protocols, simulations, and hands-on experiments.
## 💻 Lab Sessions
The lab sessions are organized into separate folders. Each folder contains:
- **Lab Instructions**: Detailed instructions for the lab session.
- **Source Code**: The code written during the lab session.
- **Documentation**: Additional documentation and notes.
Feel free to explore the repository and get hands-on experience with computer networks. **Happy Networking!**

## Week 1 : Lab Session 1 : Overview of C Programming
| **S.No.** | **Problem Statement** | **Solution File** |
|-----------|----------------------------------|-------------------------------|
| **1.1** | WAP to swap 2 numbers both by call by value and call by address. | [Solution](./Lab-Codes/1.1.c)|
| **1.2** | WAP to declare a structure having data members & display its content. | [Solution](./Lab-Codes/1.2.c)|
| **1.3** | WAP to accept array of employee in structure & print them in sorted way. | [Solution](./Lab-Codes/1.3.c)|
| **1.4** | WAP to accept 10 numbers using dynamic array & find sum & average of numbers. | [Solution](./Lab-Codes/1.4.c)|
| **1.5** | WAP to enter a statement from console and write it to a file and read its content from the same file. | [Solution](./Lab-Codes/1.5.c)|
## Lab Session 2 : Basics of Socket Programming
| **S.No.** | **Problem Statement** | **Solution File** |
|-----------|----------------------------------|-------------------------------|
| **2.1** | Write a simple datagram program to establish client server communication. | [server](./Lab-Codes/2.1s.c) [client](./Lab-Codes/2.1c.c)|
| **2.2** | Write a sender and receiver program in C by passing the IP address and the port number of each other through the command line arguments using connection less socket. Both of them will exchange messages with each other continuously. If any one of them will receive the “exit” message from the other end then both of them will close the connection. (Assume both the client and server are running with in the same host) ~ given in Lesson Plan | [Receiver](./Lab-Codes/2.2r.c)
[Sender](./Lab-Codes/2.2s.c)|
## Lab Session 3 : Connection Oriented Socket Programming
| **S.No.** | **Problem Statement** | **Solution File** |
|-----------|----------------------------------|-------------------------------|
| **3.1** | WAP to add two numbers & show their sum in client server model. | [server](./Lab-Codes/3.1s.c) [client](./Lab-Codes/3.1c.c)|
| **3.2** | WAP to swap two numbers in TCP | [server](./Lab-Codes/3.2s.c) [client](./Lab-Codes/3.2c.c)|
| **3.3** | WAP in TCP for a number sent by the client to the server and check whether it is an Armstrong number or not. | [server](./Lab-Codes/3.3s.c) [client](./Lab-Codes/3.3c.c)|
| **3.4** | WAP in TCP for an array of integer sent by the client to the server and return maximum, minimum, sum and average of all the numbers. | [server](./Lab-Codes/3.4s.c) [client](./Lab-Codes/3.4c.c)|

## ⚙️ Installation
To set up the environment for the lab exercises, follow these steps:
1. Clone the repository:
```sh
git clone https://github.com/abhinav9444/CN-Lab.git
2. Navigate to the Lab-Codes directory:
Copy code from different Laboratory session and execute them on your local machine for implementation.
```sh
cd .\CN-Lab\Lab-Codes\
```
3. Compile the sender and receiver programs using gcc:
```sh
gcc sender.c -o sender
gcc receiver.c -o receiver
```
4. First, run the receiver program:
```
.\receiver.exe
```
5. Open another command prompt (cmd) or PowerShell and run the sender program:
```
.\sender.exe
```
