Run-Time Type Identification (RTTI)

Run-Time Type Identification (RTTI)?
Run-Time Type Identification (RTTI) in C++ allows you to determine the type of an object during program execution. This is particularly useful when working with polymorphism and inheritance. C++ provides two primary mechanisms for RTTI: the typeid operator, which retrieves type information, and the dynamic_cast operator, which safely converts pointers or references between types at runtime, handling potential casting failures gracefully. While powerful, be mindful that RTTI can introduce some performance overhead due to the runtime checks involved.
