What are the best practices for using destructors in C++?

When using destructors in C++, it's important to ensure proper resource management. Always release resources like memory or file handles to prevent leaks.

Can you explain why it's important to have a destructor?

Destructors are crucial for cleaning up resources when an object goes out of scope. They help prevent memory leaks and ensure that resources are properly released.

What happens if I forget to implement a destructor?

If you forget to implement a destructor, the default destructor will be called, which may not release resources properly, leading to memory leaks.

Are there any specific scenarios where I should avoid using destructors?

Yes, if your class doesn't manage any resources or if it uses smart pointers, you might not need a custom destructor.
