Sure! You can declare a raw pointer like this: int* ptr;. To use it, you can allocate memory with ptr = new int;.

What are the risks of using raw pointers?

The main risks include memory leaks, dangling pointers, and undefined behavior if you access memory that has been freed.

How can I avoid these risks when using raw pointers?

You can avoid risks by ensuring proper memory management, using smart pointers, and always initializing your pointers.
