How can I use smart pointers in my legacy C++ code?

You can start by identifying raw pointers in your code and replacing them with smart pointers like std::unique_ptr or std::shared_ptr.

What are the benefits of using smart pointers over raw pointers?

Smart pointers help manage memory automatically, reducing the risk of memory leaks and dangling pointers.

Are there any specific challenges I should be aware of when converting to smart pointers?

Yes, you may encounter issues with ownership semantics and circular references, especially with std::shared_ptr.

Can you give me an example of converting a raw pointer to a smart pointer?

Sure! If you have a raw pointer like MyClass* obj = new MyClass();, you can convert it to a smart pointer like this: std::unique_ptr<MyClass> objPtr = std::make_unique<MyClass>();.
