How can I convert legacy C++ code to modern C++?

To convert legacy C++ code to modern C++, start by identifying outdated practices and libraries. What specific code or features are you working with?

I'm dealing with a lot of raw pointers and manual memory management.

You can replace raw pointers with smart pointers like std::unique_ptr and std::shared_ptr. This will help manage memory automatically. Have you used smart pointers before?

Not really, can you give me an example of how to use them?

Sure! Instead of using new and delete, you can create a std::unique_ptr like this: std::unique_ptr<MyClass> ptr = std::make_unique<MyClass>();. This automatically handles memory for you.

That sounds great! What about using the STL instead of custom data structures?

Using the Standard Template Library (STL) is a good idea! It provides efficient data structures like std::vector and std::map. Would you like examples of how to replace your custom structures?
