What is RTTI?

• Run-time type information (RTTI) is a mechanism that allows the type of an object to be determined during program execution. RTTI was added to the C++ language because many vendors of class libraries were implementing this functionality themselves.

• RTTI is an acronym for run time type information. RTTI is a C++ mechanism which allows the type of an object to be determined (or even set) at run-time. RTTI does not exist in Java.
  
  There are three main C++ language elements to run-time type information:
  • dynamic_cast operator
  • typeid operator
  • type_info object which is produced by typeid
  
  The dynamic_cast operator is used for identifying the exact type of an object.
  The typeid operator is used to hold the type information returned by the typeid operator.
