When should I use raw pointers in C++?

When should I use raw pointers in C++?

Raw pointers in C++ should be used when you need direct memory management, such as for performance-critical applications.

Can you give me an example of when to use them?

Sure! You might use raw pointers in a performance-sensitive area, like in a game engine, where you need to manage memory manually for speed.

What are the risks of using raw pointers?

The main risks include memory leaks, dangling pointers, and undefined behavior if the memory is accessed after being freed.

Are there alternatives to raw pointers?

Yes, alternatives include smart pointers like std::unique_ptr and std::shared_ptr, which help manage memory automatically.
