How do I use std::unique_ptr with arrays in C++?

How do I use std::unique_ptr with arrays in C++?

You can use std::unique_ptr with arrays by specifying the array type in the template. For example: std::unique_ptr<int[]> ptr(new int[10]);.

What happens if I forget to specify the array type?

If you forget to specify the array type, it will not compile, as std::unique_ptr needs to know the type it manages.

Can I use std::unique_ptr with a custom deleter for arrays?

Yes, you can use a custom deleter by passing it as a second argument: std::unique_ptr<int[], CustomDeleter> ptr(new int[10], CustomDeleter());.

Are there any limitations I should be aware of?

One limitation is that std::unique_ptr cannot be copied, only moved. Also, ensure the array size is known at compile time.
