Consider the following code segment and answer questions 14 and 15. class Point { public: Point (double x = -99, double y = -99) { this -> xM = x; this -> yM = y;} double getx () {return xM; } double gety () {return yM; } void setx (double x) {this -> xM = x; } void sety (double y) {this -> yM = y; } private: double xM, yM; }; 14. What is the output of the following code snippet: Point pl (100); cout << pl.getx() << " " << pl.gety(); a. The output of the program is: -99 -99 b. The output of the program is: 100 100 c. The output of the program is: -99 100 d. The output of the program is: 100 -99 e. None of the above. It doesn't compile because constructor of Point needs two arguments. 15. How many times does the constructor of class Point get called by the following code snippet: Point a (100, 200); Point b[6]; Point *c = new Point; Point *d = new Point (300, 400); a. Four times b. Three times c. Nine times d. Two times e. None of the above

Static vs. non-static class data members: What real-world circumstance might benefit from a static data member?

This code is used for the question being asked at the bottom.   public class AccountBalance {private long accountNumber;private String ownersName;private double balance;public AccountBalance(long accountNumber, String ownersName, double balance) {this.accountNumber = accountNumber;this.ownersName = ownersName;setBalance(balance);}public long getAccountNumber() {return accountNumber;}public void setAccountNumber(long accountNumber) {this.accountNumber = accountNumber;}public String getOwnersName() {return ownersName;}public void setOwnersName() {this.ownersName = ownersName;}public double getBalance() {return balance;}public void setBalance(double balance) {if (balance < 0) {System.out.println("Balance Cannot be Negative.");balance = 0;}this.balance = balance;}} import java.util.Scanner;public class AccountBalanceDemo {public static void main(String[] args) {Scanner sc = new Scanner(System.in);System.out.print("Enter the name of the account holder: ");String name =…
