Welcome to Week 5! 🎉 This week, we’ll explore functions in C++, essential tools for writing clean and efficient programs. By the end, you'll learn how to define and use functions, leverage built-in functions. Let’s get started! 🚀

---

• 🌱 Learn how to define functions in C++, understand their purpose, and how they make programming more organized and reusable.
• 💡 Discover how to:
  • Define functions in C++.
  • Call functions and pass data to them.
  • Retrieve information from functions (return values).
• 🚀 Explore built-in functions in C++ that are critical for efficiency:
  • Built-in functions save significant effort by providing ready-made solutions.
  • They enhance code speed and brevity, allowing you to focus on more complex problems.
