which of the following access modifier can be used if you want the member to be accessible to all external code? Protected any access modifier public private default

Which statement of the following is the most appropriate? Group of answer choices When you design a class, always make an explicit statement of the rules that dictate how the member variables are used. These rules are called the invariant of the class, and should be written at the botttom of the implementation file for easy reference. When you design a class, always make an explicit statement of the rules that dictate how the member variables are used. These rules are called the variant of the class, and should be written at the botttom of the implementation file for easy reference. When you design a class, always make an explicit statement of the rules that dictate how the member variables are used. These rules are called the invariant of the class, and should be written at the top of the implementation file for easy reference. When you design a class, always make an explicit statement of the rules that dictate how the member variables are used. These rules are called the…

Which access specifier should be used when calling member functions, constructors, and destructors? Toward what end?

Describe the access modifiers that you can use for the members of a class

When a class declares an entire class as its friend, the friendship status is reciprocal. That is, each class's member functions have access to the other's private members. True False

Design a class named Account that contains: • A private int data field named id for the account (default 0). • A private double data field named balance for the account (default 0). • A private double data field named annualInterestRate that stores the current interest rate (default 0). Assume all accounts have the same interest rate. • A private Date data field named dateCreated that stores the date when the account was created. • A no-arg constructor that creates a default account.• A constructor that creates an account with the specified id and initial balance. • The accessor and mutator methods for id, balance, and annualInterestRate. • The accessor method for dateCreated. Page 10 of 8• A method named getMonthlyInterestRate() that returns the monthly interest rate. • A method named withdraw that withdraws a specified amount from the account. • A method named deposit that deposits a specified amount to the account. • Draw the UML diagram for the class. • Implement the class. Write a…

Create a class named Student that has fields for an ID

Which access specifier should be used when calling member functions, constructors, and destructors? Toward what end?

Must be in C++ and cannot come from any online source. Please include all requested parts in problem.    Create a class named Employee that has the following member variables: name - a string that holds the employee's name empIdNumber - an int variable that holds the employee's ID Number  job - a string that holds the name of the position the employee is working in (Laborer, Manager, Secretary, etc.) yearsOfService- an integer that holds the employee's years of service The class should have the following constructors: A constructor with the following values as parameter arguments and assigns them to the appropriate member variables:  employee's name, employee ID number, job and years of service that are passed to them when the object is created (pass each of the four values into the constructor) A constructor with the following values as parameter arguments and assigns them to the appropriate member variables: employee's name and ID Number. The job field should be assigned an…

Double Bubble For this exercise you need to create a Bubble class and construct two instances of the Bubble object. You will then take the two Bubble objects and combine them to create a new, larger combined Bubble object. This will be done using functions that take in these Bubble objects as parameters. The Bubble class contains one data member, radius_, and the corresponding accessor and mutator methods for radius_, GetRadius and SetRadius. Create a member function called CalculateVolume that computes for the volume of a bubble (sphere). Use the value 3.1415 for PI. Your main function has some skeleton code that asks the user for the radius of two bubbles. You will use this to create the two Bubble objects. You will create a CombineBubbles function that receives two references (two Bubble objects) and returns a Bubble object. Combining bubbles simply means creating a new Bubble object whose radius is the sum of the two Bubble objects' radii. Take note that the CombineBubbles function…
