Suppose you have class A and class B,under which of the following two conditions class B should inherit from class (1)A is a part of B.(2)B is a kind of A.2.When should the keyword virtual be placed before a member function of a class?Do all of the virtual member functions have...
Polymorphism promotes code maintenance by reducing code duplication. With polymorphism, you can define a method once in a superclass and have all its subclasses inherit and override it as needed. This avoids the need to duplicate code across multiple classes, making the codebase easier to maintain...
Inheritance is mainly used to implement the same code multiple times, i.e., reusing code. This would reduce the program's length and complexity. In this process, a child class derives data members and methods of a class that is previously created. The former one is also termed as the ...
This means that even if the class can be instantiated, obj1.__setstate__(obj2.__getstate__()) will have no effect on obj1. Python pickle module uses: inst = cls.__new__() inst.__setstate__(state) The return value for __setstate__ is ignored: https://github.com/python/c...
What should I do when the error message "must have required property 'startWindowIcon'" is displayed during the UIAbility startup? How is data returned when startAbilityForResult() is called? How do I start an application using implicit want when the UIAbility is unknown? What should ...
How do I resolve the issue where the window created by Window does not have the default focus , leading to unresponsiveness to the return event? How do I obtain the height of the status bar and navigation bar? Does ArkUI have chart components? How do I implement a custom dialog box...
In a human understanding, or non-technical, the constants can be considered as something you buy and don’t have an exchange policy. Or in other words, you buy some books, take any number of books, and taking the bag as a constant, those books once placed in the bag, cannot be repla...
Can partial class definitions have multiple constructors? Can someone explain this code to me? (Visual C#) Can Struct stored in heap?! can VB & C# to be used in same project? Can we add derived class object to base class object? Can we change the return type of a method during overri...
it looks like you are requiring us to extendReactiveObjecttoo, which is not possible (no multiple inheritance in C#). So the only thing that works is using Rx bindings where there are noPropertyChangedevents fired (interestingly, that works). But that's not a permanent solution, I think you...
1. Describe the chromosomal theory of inheritance. 2. Explain how chromosomal abnormalities can lead to genetic disorders. What is the chromosomal theory of inheritance? How have studies using ancient DNA changed our understanding of the process of heredity? How does epigenet...
