When should I use raw pointers over smart pointers?

Question

After reading this answer, it looks like it is a best practice to use smart pointers as much as possible, and to reduce the usage of \"normal\"/raw pointers to minimum.

Answer 1

Few cases, where you may want to use pointers:

• Function pointers (obviously no smart pointer)
• Defining your own smart pointer or container
• Dealing with low level programming, where raw pointers are crucial
• Decaying from raw arrays
