The override keyword serves two purposes: It shows the reader of the code that "this is a virtual method, that is overriding a virtual method of the base class." The compiler also knows that it's an override, so it can "check" that you are not altering/adding new methods that you think are overrides.
C # in Telugu The function overriding is the most common feature of C++. Basically function overriding means redefine a function which is present in the base class, also be defined in the derived class. So the function signatures are the same but the behavior will be different.
The name override in the method declaration expresses that the method should override a virtual method of a base class. The compiler checks the assertion. It checks the parameter of the method, the return type of the method, and qualifiers like const and volatile.
override (C# reference) The override modifier is required to extend or modify the abstract or virtual implementation of an inherited method, property, indexer, or event. An override method provides a new implementation of the method inherited from a base class.
You can't put an override specifier when defining the function outside the class's member specification. The language doesn't allow it, and a compiler will complain. So there's really only one option.
Beyond that, this option also makes more sense. When declaring the function you are expressing an intent to override it. So putting override there at the point of expressing your intent makes sense. That is what you are asking the compiler to check here, your intent to override. The declaration is also enough to verify that function is originally declared virtual and that you got the signature right.
