improve(docs): Basics -> Arrays

[PoetaKodu]

Overview

Make the lesson structure fit the following (note the actual names of the course lessons are in bold):

Arrays

• 1. Introduction
  • Motivation: why do we want to use them.
  • Arrays in C++: types of arrays in the language
• 2. Dynamic arrays
  • Lesson structure
    • creating a vector
    • accessing elements
    • adding elements
    • removing elements
    • reading size
    • displaying elements
  • 💡 Examples
  • 💢 Common problems
  • 📚 Exercises
• 3. Fixed-size arrays
  • Lesson structure
    • creating an array
    • accessing elements
    • note about not being able to add or remove elements
    • filling the content
    • reading size, mention that it is always the same
    • displaying elements
  • 💡 Examples
  • 💢 Common problems
  • 📚 Exercises
• 4. Using algorithms - show examples that require minimal knowledge of the language but allow the reader to play with vectors and arrays
  • max value with std::ranges::max()
  • min value with std::ranges::min()
  • reverse with std::ranges::reverse()
  • sorting with std::ranges::sort()
  • ensure the lesson properly shows both std::array and std::vector examples
• 5. C-style arrays
  • explain why we don't want to use C-style arrays
  • describe when and how to use safer alternatives instead
  • provide basic examples of C-style array usage
• 📚 Exercises
