(JAVA) What is code refactoring?   Group of answer choices   A)None of the options are correct.   B) It is changing implementation of a method or constructor of a class, while leaving the declaration the same, allowing all users of that class to continue using the class without noticing the change.   C)It is abstracting a class so that common elements with another class are moved into the abstract class that both classes extend.   D) It is declaring all the methods that need to be supported in an interface. This guarantees that all classes implementing this interface will support those methods.

C++ Using Card and Deck class created during the lecture or your own implementation that follows the spec for a card and deck, implement the following game: game is designed for a single player who is playing against the computeryou draw three cards for each player (player and a computer) Using the compare function from the Card class you compare each pair drawnIf the player's card is higher, the player gets a pointYou repeat this comparison 3 times (for each pair of cards you draw)The player wins if he gets more points than a computer (has more higher cards than the computer)

“Dangling and wild pointers are known to be problems with pointers”. Justify the given statement with the help of suitable examples. -C language

Explain the type of inheritance with the examples.   (Use C++)

Java Assignment: Experiment with naming rules in Java Does the language use static or dynamic scoping? Can scopes nest? Are they open or closed? Does the scope of a name encompass the entire block in which it is declared, or only the portion after the declaration? How does one declare mutually recursive types or subroutines? Can subroutines be passed as parameters, returned from functions, or stored in variables? If so, when are referencing environments bound? Justify your answers with suitable code snippet and its output.
