🚀 In Part 11 of the Mastering Programming Using C series, we move from theory to real-world examples of functions in action. This hands-on session reinforces your understanding of how functions work in C through practical, beginner-friendly exercises.

✅ What you’ll learn in this video:
✔️ Writing and calling user-defined functions
✔️ Passing parameters (by value)
✔️ Returning values from functions
✔️ Reusable logic with multiple functions
✔️ Examples:
  🔹 Sum of two numbers
  🔹 Finding factorial
  🔹 Checking prime numbers
  🔹 Swapping values using functions
✔️ Best practices for structuring and organizing function-based programs

💡 Why This Matters:
🔹 Strengthens your function fundamentals through real coding
🔹 Builds logical thinking with reusable code blocks
🔹 Prepares you for solving interview problems and building mini projects
🔹 Reinforces the concept of modular programming
