orphism.
- Creating classes and objects: Learn how to define classes and create objects (instances) from those classes to represent real-world entities.
- Encapsulation, inheritance, and polymorphism: Dive deeper into OOP concepts and discover how encapsulation helps in data hiding, inheritance facilitates code reuse, and polymorphism allows objects of different classes to be treated interchangeably.
8. Pointers and Memory Management:
- Understanding pointers and memory addresses: Explore the concept of pointers, which hold memory addresses, and understand how they can be used for more advanced memory manipulation.
- Dynamic memory allocation using new and delete operators: Learn how to dynamically allocate memory at runtime using the new operator and release it using the delete operator to manage memory efficiently.
- Memory management and avoiding memory leaks: Discover best practices for proper memory management, including avoiding memory leaks and dealing with dangling pointers.
