What are unique pointers in C++ templates?

Can you explain what unique pointers are in C++ templates?

Unique pointers are smart pointers that ensure a single ownership of a dynamically allocated object. In templates, they can manage resources efficiently.

How do I use unique pointers in a template class?

You can define a template class that holds a unique pointer as a member. For example: template <typename T> class MyClass { std::unique_ptr<T> ptr; };.

What are the advantages of using unique pointers?

Unique pointers help prevent memory leaks by automatically deallocating memory when the pointer goes out of scope. They also provide better exception safety.

Can unique pointers be copied?

No, unique pointers cannot be copied because they maintain exclusive ownership. However, they can be moved using std::move().
