here void functions are methods
C: there are no methods in C. C++: no.
You declare a class as follows: class MyClass { //some stuff here... } You create an object as follows: MyClass object; This is how you create classes and objects in C++.
In Java, or in any object oriented language such as C++, a method defined in super (parent) class does not need to be defined in a subclass, because that is the primary purpose of inheritance. Object oriented programming allows you to define and declare a class that implements the behavior for an object. Inheritance allows you to refine, or subclass, that class by "reusing" all of the functionality of the parent class into the sub class, adding additional definition and declaration for the sub class. If the subclass needs to change a parent class method, it can overload that method. This is called abstraction.
Yes. Any base class method that is declared virtual can be overridden by a derived class. Overriding a method that is not declared virtual can still be called, but will not be called polymorphically. That is, if you call the base class method, the base class method will execute, not the override. To call a non-virtual override you must call it explicitly.
In C++, methods are simply class member functions.
Unlike abstract class in C++, the abstract class in C# does not have any methods defined as virtual by default. The concept of virtual are not the same between C# and C++, either. Any virtual method must be defined explicitly in C#. Related to abstract methods - interestingly, an abstract class in C# does not have to have any abstract methods. However, the reverse, if a class need to have at least one abstract method, that class must be defined as abstract.
yes it is possible to make a private class in C++ but this class will not solve any purpose.................
Virtual method invocation is a term borrowed from C++. It means that methods are invoked polymorphically. Instead of invoking the method in the compile-time type, the method is invoked as its runtime type. In C++, you declare methods virtual that are executed this way.
You don't need a typedef to declare a struct in C++. A struct is declared exactly the same way that you would declare a class, the only difference being that struct members are public by default, while class members are private by default. Aside from that the class and struct keywords are completely interchangeable.
In Visual C++, or C# you can use static method Directory or non-static DirectoryInfo.
class class_name { private: data_members; public: member_functions; };
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
