consider the following code snippet: class A{ public: A0{ class B: private A{ B); }; main0{ B *b = new B0; O a. the constructor of the class B will be executed then the constructor of class A O b. None of the constructors will be executed O c. the constructor of the class A will be executed then the constructor of class B O d. All other answers are wrong

PLZ help wiith the following: IN JAVA If an inner class contains non static members, then the class name must be modified by the keyword: Final Static Void Protected

Why might a class need to implement a destructor?

Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works.  Next add the following public methods to the Address class and test them from main as you go: Write getters and…

A programmer has submitted the following class declaration for approval. This will be part of a program that tracks departments within a company and employees assigned to those departments. class Employee { public: Employee(); string getName(); long getldentifier(); Dollars getSalary(): Department worksln(): void assignTo (Department"); Employee getSupervisor() (return dept->getManager();) private: string name; long identifier; Department" dept; Dollars salary: Based upon this information, which of the C++ checklist items appear to be in violation? O Interface completeness O Meaningful names O Undocumented pre-conditions O All data members private O Every constructor initializes every data member O Appropriate treatment of default constructor O Appropriate treatment of the Big 3 O Appropriate relational operators O Appropriate output function D Const correctness

Class A is composed of objects of class B, class B is extended by C& D. There should be a copy constructor in: A, B, C and D C and D only B only O B, C, and D
