# Git & GitHub Basics

## Introduction

- **Git** was created by *Linus Torvalds* in 2005.

- It is a free, open-source, distributed version control system used to track changes in source code and other files during software development.

- **GitHub** is a cloud-based hosting service for Git repositories, enabling collaboration and version control.

## Commands

### Navigation (cd and dir)

- cd <path> → Change directory (go to folder).

- cd .. → Move one directory back.

- cd \\ → Goes to root directory (Windows).

- cd . → Refers to the current directory.

- dir (Windows) / ls (Linux) → List files and directories.

## CLI vs GUI

**CLI (Command Line Interface):**

- Text-based interaction.

- Requires commands like cd, dir, ls.

- Lightweight and faster once mastered.

**GUI (Graphical User Interface):**

- Visual interaction using windows, icons, buttons.

- Easier for beginners.

- Heavier on resources compared to CLI.

## Developer & User Experience

- Developer Experience:** Tools and workflows that make development smooth, efficient, and error-free.

- User Experience (UX):** How end-users interact with applications, focusing on simplicity, usability, and satisfaction.

Task 4: Fibonacci Program

# Fibonacci sequence

def fib(n):

  if n <= 1:

  return n

  else:

  return fib(n-1) + fib(n-2)

n = int(input("Enter number of terms: "))

if n < 0:

  print("Enter a positive number")

else:

  for i in range(n):

  print(fib(i), end=" ")
