How do I convert raw pointers to smart pointers in C++?

You can convert raw pointers to smart pointers using std::unique_ptr or std::shared_ptr. Which one are you interested in?

What's the difference between unique_ptr and shared_ptr?

unique_ptr is for exclusive ownership, meaning only one unique_ptr can own the resource. shared_ptr allows multiple pointers to share ownership.

Can you show me an example of converting a raw pointer to a unique_ptr?

Sure! Here's an example:

int* rawPtr = new int(10);
std::unique_ptr<int> smartPtr(rawPtr);

This transfers ownership of the raw pointer to the unique_ptr.

What happens to the raw pointer after conversion?

After conversion, the raw pointer should not be used directly, as the unique_ptr now manages its lifetime.
