How do I use unique_ptr in C++ templates?

Can you explain how to use unique_ptr in C++ templates?

Sure! unique_ptr is a smart pointer that manages the lifetime of a dynamically allocated object. In templates, you can use it to ensure proper memory management.

What are the benefits of using unique_ptr over raw pointers?

The main benefits include automatic memory management, prevention of memory leaks, and ensuring that the object is deleted when the unique_ptr goes out of scope.

Can you show me a simple example of a template function using unique_ptr?

Absolutely! Here's a simple example:

#include <memory>

template <typename T>
void process(std::unique_ptr<T> ptr) {
    // Process the object pointed to by ptr
}

Are there any limitations when using unique_ptr in templates?

Yes, unique_ptr cannot be copied, only moved. This means you need to be careful with ownership transfer in your template functions.
