Declaring member functions of the parent classes using virtual functions

[Shr_Bong]

How are override identifiers helping while declaring member functions of the parent classes using virtual functions?

[CStrike07]

The override identifier asks the compiler to display error messages when these blunders are made. In the absence of these error messages, even though the program might compile, there’s a possibility that the virtual function does not get overridden like the case of using  Incorrect function names, Non-matching function parameters, No function is defined as virtual in the parent class there many other use case of override identifiers in virtual functions most of them are listed here in this Scaler article, I’d strongly recommend going through it.
