Description: We need to add content to our C++ learning project that explains the Big Five in Object-Oriented Programming (OOP). This section should provide a clear and detailed explanation of each of the Big Five: the default constructor, the destructor, the copy constructor, the copy assignment operator, and the move constructor and move assignment operator. The contributor should ensure that the explanations are beginner-friendly and cover the following main points:

1-Introduction to the Big Five:

• Explain the significance of the Big Five in C++.
• Overview of resource management and object lifetime in C++.

2-Default Constructor:

• Define the default constructor.
• Explain when it is automatically provided by the compiler.
• Provide an example and discuss its typical use cases.

3-Destructor:

• Define the destructor.
• Explain its role in resource management.
• Provide an example, especially in the context of dynamic memory allocation.

4-Copy Constructor:

• Define the copy constructor.
• Explain the need for a copy constructor and when it is used.
• Provide an example and highlight the differences between shallow and deep copying.

5-Copy Assignment Operator:

• Define the copy assignment operator.
• Explain its role and when it is invoked.
• Provide an example and discuss its implementation details, including self-assignment checks.

6-Move Constructor and Move Assignment Operator:

• Define the move constructor and move assignment operator.
• Explain the concept of move semantics and why they are important.
• Provide examples of both, showing how they improve performance by transferring resources instead of copying them.

7-Rules of Three, Five, and Zero:

• Explain the Rules of Three, Five, and Zero in C++.
• Discuss best practices for implementing the Big Five.

8-Conclusion:

• Summarize the key points.
