When should I use unique_ptr instead of raw pointers in C++?
You should use unique_ptr when you want to ensure that an object has a single owner and is automatically deleted when it goes out of scope. This helps prevent memory leaks.
Can you explain the advantages of using unique_ptr over raw pointers?
Certainly! Unique_ptr provides automatic memory management, prevents double deletions, and makes ownership semantics clear, which enhances code safety.
Are there any situations where raw pointers are still preferable?
Yes, raw pointers can be useful for non-owning references or when interfacing with legacy code that doesn't use smart pointers.
What about shared_ptr? When should I use that instead?
Use shared_ptr when you need shared ownership of an object, meaning multiple pointers can own the same resource. However, be cautious of potential circular references.
