What information is missing?

1-Introduction to Copying Objects:

• Overview of object copying in C++.
• Clear definitions and distinctions between deep copying and shallow copying.
• Shallow Copying:

2-Define shallow copying.

• Describe how a shallow copy duplicates the object's top-level structure but not the elements contained in deeper levels (e.g., pointers).
• Provide a simple example of shallow copying.
• Discuss potential issues with shallow copying, such as double-free errors and unintended side effects.

3-Deep Copying:

• Define deep copying.
• Explain how a deep copy duplicates not only the object's top-level structure but also the elements contained in deeper levels (e.g., pointers).
• Provide a simple example of deep copying.
• Highlight the advantages of deep copying, such as avoiding issues related to shared ownership of dynamically allocated memory.

4-Implementing Deep Copy and Shallow Copy in C++:

• Show how to implement a shallow copy using the default copy constructor and assignment operator.
• Demonstrate how to implement a deep copy by defining a custom copy constructor and assignment operator.
• Include code snippets and detailed explanations.

5-Use Cases and Best Practices:

• Discuss scenarios where shallow copying might be sufficient or desirable.
• Explain situations where deep copying is necessary.
• Offer best practices for deciding between shallow and deep copying.

6-Conclusion:

• Summarize the key points.
• Provide additional resources or references for further reading.
