What are the drawbacks of using function pointers in C++?

Function pointers can lead to code that is harder to read and maintain. They can also introduce risks like dangling pointers.

Can you explain what a dangling pointer is?

A dangling pointer occurs when a pointer still points to a memory location that has been freed or deallocated.

Are there alternatives to function pointers?

Yes, alternatives include using functors, lambda expressions, or std::function, which can provide better type safety.

How do lambda expressions improve safety?

Lambda expressions capture variables by value or reference, reducing the risk of dangling pointers and improving readability.
