Runtime type identification (RTTI) lets you find the dynamic type of an object when you have only a pointer or a reference to the base type. RTTI is the official way in standard C++ to discover the type of an object and to convert the type of a pointer or reference (that is, dynamic typing). The need came from practical experience with C++. RTTI replaces many homegrown versions with a solid, consistent...

Overloading a method (or function) in C++ is the ability for functions of the same name to be defined as long as these methods have different signatures (different set of parameters). Method overriding is the ability of the inherited class rewriting the virtual method of the base class.

swarn kant

• Mar 14th, 2006

All the above answers are right this is one more refinement.overridding is runtime polymorphism while overloading is compile time polymorphism. 

priya

Overloading: the same function can perform different operations.overridding: the derived class can rewrite the content of the base class.

By adding key word inline before the function name in the declaration, allows the function to be defined in the same file, in most case the header or the .h file without doing so in .cpp file.Eg:-inline LONG GetSeedValue(CEndUserRec* record) {    return record->ENDUSERSID;}
