- protected class members are only accessible inside the class (true/false)
- it’s possible to set the value of a private member variable of a class (true/false)
- setter and getter functions should be private (true/false)
Step by step
Solved in 2 steps
- True/False: a member function in a class can access all of its class's member variables, but not if the variables are private. A) True B) FalseTrue/False: a member function in a class can access all of its class's member variables, but not if the variables are protected.C++ True/False: a member function in a class can access all of its class's member variables, but not if the variables are private.
- Write base class with the name Shape . The Shape class have Private Variable: area, a double used to hold the shape's area. Public Member Functions: getArea the Accessor. This function should return the value in the member variable area. Parameterized constructor—Initializes area member. Defualt constructor— Empty body calcArea. This function should be a incomplete function.Next, define a class named Triangle . It should be child of Shape class. It should have the following members:Protected Member Variables: base, a integer used to hold the base of triangle.Height, a integer used to hold the height of the triangle. Public Member Functions: constructor—Initializes values for base, height. The overridden calcArea function in Circle described below.calcArea—calculates the area of the Triangle (1/2* base * height) and stores the result in the inherited member area.After you have created these classes, create a driver program that defines a Triangle object. Demonstrate that each object…True or FalseA base class reference variable can reference an object of any class that is derived from the base class.Circle Class (Easy) Write a Circle class that has the following member variables: radius : a double The class should have the following member functions: Default Constructor: default constructor that sets radius to 0.0. Constructor: accepts the radius of the circle as an argument. setRadius: an mutator function for the radius variable. getRadius: an accessor function for the radius variable. getArea: returns the area of the circle, which is calculated as area = pi * radius * radius getCircumference: returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius Step1: Create a declaration of the class. Step2: Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating Circle objects, and then reporting the circle’s area, and circumference. You should create at least two circle objects, one sets the radius to 0.0 and one accepts the radius as 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…True or False: 1. Data items in a class may be public. 2. Class members are public by default. 3. Friend functions have access only to public members of the class.Construct a Time class containing integer data members seconds, minutes, and hours. Have the class contain two constructors: The first should be a default constructor having the prototype Time(int, int, int), which uses default values of 0 for each data member. The second constructor should accept a long integer representing a total number of seconds and disassemble the long integer into hours, minutes, and seconds. The final member method should display the class data members.
- Using C# Language: Programming PLO 3 Measured: Create control structures, methods with the appropriate parameters, and data structures of the appropriate type, and implement algorithms to solve problems. Design a class named Contractor. The class should keep the following information: Contractor name Contractor number Contractor start date Write one or more constructors and the appropriate accessor and mutator functions for the class. Write another class named Subcontractor that is derived from the Contractor class. The Subcontractor class should have member variables to hold the following information: Shift (an integer) Hourly pay rate (a double) The work is divided between two shifts, a day shift, and a night shift. The shift variable will hold an integer value representing the shift that the subcontractor will work. The day shift is 1 and the night shift is 2. Write one or more constructors and the appropriate accessor functions for the class. Demonstrate the classes…Class members are accessed via the________ operator in conjunction with the name ofan object (or reference to an object) of the class or via the_____________ operator in conjunction with a pointer to an object of the classCreate an Employee class that includes three private data members— firstName (type string), lastName (type string), and monthlySalary (type int ).It also includes several public member functions.1. A constructor initializes the three data members. 2. A setFirstName function accepts a string parameter and does not return any data. It sets the firstName.3. A getFirstName function does not accept any parameter and returns a string. It returns the firstName.4. A setLastName function accepts a string parameter and does not return any data. It sets the lastName.5. A getLastName function does not accept any parameter and returns a string. It returns the lastName.6. A setMonthlySalary function accepts an integer parameter and does not return any data. It sets the monthlySalary. If the monthly salary is less than or equal zero, set it to 1000 and it displays the employee’s first name, last name and the inputted salary with a statement “**==The salary is set to $1000.”7. A getMonthlySalary…
