Multiple overridingIn native C++, a function of a class that inherits from multiple base classes/interfaces, can override more than one base class function only if all the base classes/interfaces have a function of the same name and signature. C++/CLI lets you specify which method overrides whi...
Overriding standard C library functions in C++ program, Overriding is a completely different concept from overloading. You override a virtual member function. No overloading takes place here. What actually happens is you are defining printf with the exact same signature as stdio.h declares. So i...

Functions with incorrect names: For example, if the virtual function in the base class is named print(), but we accidentally name the overriding function in the derived class as pint(). Functions with different return types: If the virtual function is, say, of void type but the function ...
They're used in distinguishing between overloaded functions: C++ Copy void Print( char szToPrint[] ); void Print( char szToPrint[][7] ); void Print( char szToPrint[][9][42] ); Overloading, overriding, and hidingAny two function declarations of the same name in the same scope can...
If the base class function isn't declared asvirtual, then the derived class function is said tohideit. Both overriding and hiding are distinct from overloading. Block scope is strictly observed. A function declared in file scope isn't in the same scope as a function declared locally. If ...
