Can you use the same function name for a member functoin of a class and an outside function in the same program file?

Yes you can use the same function name for a member function and an external function. They are primarily distinguished by the number and type of arguments they accept (the function signature). If they match exactly, then the scope resolution operator (::) is used to differentiate them by namespace. The class namespace is the class name itself. The external function uses global scope unless scoped to another namespace. When the scope is not explicitly stated, then the scope is implied by the call site. Note that whenever there is any ambiguity about which function is implied, the compiler will emit an error indicating where the ambiguity lies, and the program will ultimately fail to compile.


What condition a function must specify in order to create objects of a class?

The object must have same name as that of class name.


What is self referential function in c plus plus?

A self-referential function in C++, or in any other supporting language, is a recursive function.


What is member fusion in c plus plus?

If you are asking about member functions. When we declare a function inside a class then that function becomes member function of that class and this function can access the whole class


What is the difference between virtual function and function overriding?

Virtual Functions and Pure Virtual Functions are relevant in the context of class inheritance.Unlike Virtual Functions, Pure Virtual Functions do not require a body. This implies that when a base class defining such a function is inherited, the derived class must implement that function. Furthermore, the base class becomes abstract; meaning you cannot create an instance of the base class even if a body is implemented for the function. You are expected to derive from abstract classes; only the derived classes that implement all the inherited Pure Virtual functions can be instantiated.Here are some examples of Virtual and Pure Virtual function signatures:- Virtual Function: E.g. virtual void myFunction();- Pure Virtual Function: E.g. virtual void myFunction() = 0;

Hormones within a chemical class have the same function, but act on different substrates.


What is the pupouse of static function?

A static function, not part of a class, is visible only to other code within the same compilation unit, i.e. the same source file. A static function, part of a class, can only operate on static class data, which is per class data as opposed to per instance data.


What is conustrutor?

A constructor is a function in C which has the same name of the class. The constructor can be used to initialize some function.

How do virtual functions differ from pure virtual functions?

Virtual functions is a function that can be overridden in inheriting class with the same signature (function name, parameters number, parameters types and return type);Pure virtual function is function that does not have implementation and if class has pure virtual function is called abstract. It is not possible to instantiate that class. Some other class must inherit it and define the body for it (implement). In other words class only have function prototype/declaration(signature) and no definition(implementation).


When the concept of method overriding is necessary?

concept of overriding is very important as due to overriding the derived class can use the function of the base class! when the function has same name and prototype in both the classes(base and derived) then the derived class can use the funtion of base class!
