What are unique pointers in C++ and how do they work?
Unique pointers are smart pointers that ensure a single ownership of a dynamically allocated object. They automatically manage memory.
How do I create a unique pointer in my code?
You can create a unique pointer using std::unique_ptr<Type> ptr = std::make_unique<Type>(constructor_args);
.
What happens if I try to copy a unique pointer?
Copying a unique pointer is not allowed because it would violate the ownership principle. You can only move it.
Can you give me an example of moving a unique pointer?
Sure! You can move a unique pointer using std::unique_ptr<Type> newPtr = std::move(oldPtr);
which transfers ownership.
