This makessampleanabstract class, and if the derived class doesn't defineg(), it would also become an abstract class. You cannot create instance of any of these class, as both of them are abstract! With the following codes, I got an intellisense error of"object of abstract class type i...
An abstract class is a class that is designed to be specifically used as a base class. An abstract class contains at least one pure virtual function. You declare a pure virtual function by using a pure specifier (= 0) in the declaration of a virtual member function in the class declaratio...
Is it possible to have an overload of Initialize() in newFoo class?Or basically, can I have a unique Initialize(WCHAR* id); only in newFoo class (but not in Foo class)?Or do I have to use the different method name e.g. InitializeNewFoo() to separate from Foo::Initialize()?
An abstract class definition in Java can be described as a class that cannot be instantiated directly. It means that one cannot create an object of an abstract class. To explain with an abstract class example in Java: Imagine an abstract class named “Vehicle”. This class might have an abs...
Please suggest me the way how to create a object by calling parameterised constructor using the className string variable. I am using the following code but i am unable to invoke the parameterized constructor while creating the object using Class.forName
"The left-hand side of an assignment must be a variable, property or indexer". Help? "The remote server returned an error: (401) Unauthorized" "Typewriter" like effect in a C# Console application? "Unable to cast object of type 'System.Configuration.DefaultSection' to type blah blah ((...
There will be one MethodTable for each declared type and all the object instances of the same type will point to the same MethodTable. This will contain information about the kind of type (interface, abstract class, concrete class, COM Wrapper, and proxy), the number of interfaces ...
create the objects when we declared the class as abstract. However, we can inherit the subclasses from them so that the parent-child class relationship is applicable for these types of classes. Therefore, when we create the abstract class, we are unable to create the object for those classes...
So I have a vector of abstract clas objects and I'm trying to cast a specific element as an object of a derived class, but I'm not sure how. Here's some pseudocode to show: 12 std::vector<Abstract> objects; Derived(objects[0]).doSomething(); However, in the second line, I ge...
the base type of the class is an interface, and the class doesn't implement all of the interface's member functions. You may be unable to construct objects from a class that's derived from an interface. The reason might be that the class is implicitly abstract. For more information about...
