💡 C++ Masterclass – Pointers & Memory Management

Welcome to one of the most important lectures in C++ — Pointers and Memory! 🧠
In this video, we’ll go deep into how memory actually works in your computer, how pointers store addresses, and how to manage memory effectively using new, delete, and smart pointers.

This lecture will help you understand how your C++ program interacts with memory, which is crucial for writing efficient and bug-free code.

🔑 What You’ll Learn in This Lecture:

✔ What memory is and how variables are stored in RAM
✔ What pointers are & how they store addresses
✔ Pointer declaration, dereferencing, and pointer-to-pointer
✔ Pointer arithmetic (++, --, +, -)
✔ How arrays and pointers are related
✔ Understanding references (int &ref)
✔ Difference between NULL and nullptr
✔ Dynamic memory allocation using new and delete
✔ Common memory leaks and how to prevent them
✔ Introduction to Smart Pointers (unique_ptr, shared_ptr, weak_ptr)

🧠 Self-Practice Problems:

1️⃣ Print the value and address of a variable using a pointer
2️⃣ Use a pointer to change a variable’s value
3️⃣ Demonstrate pointer arithmetic on an array
4️⃣ Write a function using pointers to modify values
5️⃣ Create a dynamic array using new and compute its sum
6️⃣ Swap two numbers using pointers
7️⃣ Return max & min of array using pointers
8️⃣ Compare NULL and nullptr with examples
9️⃣ Dynamically allocate a 2D array and print its values
🔟 Demonstrate a memory leak and fix it using delete

🧩 Perfect For:

Students who want to truly understand memory, not just memorize syntax!
This lecture combines visual explanations, code execution, and dry runs to help you master pointers easily.
