What are some effective resource management techniques in C++?

In C++, effective resource management techniques include RAII (Resource Acquisition Is Initialization), smart pointers, and proper use of destructors.

Can you explain RAII in more detail?

RAII is a programming idiom where resources are tied to the lifetime of objects. When an object is created, it acquires resources, and when it goes out of scope, the resources are released automatically.

What are smart pointers and how do they help?

Smart pointers, like std::unique_ptr and std::shared_ptr, manage memory automatically, preventing memory leaks and dangling pointers by ensuring proper resource deallocation.

Are there any best practices for using destructors?

Yes, best practices include ensuring that destructors are virtual in base classes, avoiding resource leaks, and using them to release resources safely.
