a. 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. b. Include the class written for Exercise 4a in the context of a complete program.

Create a class called Employee that includes three pieces of information as data members—a first name (type string), a last name (type string) and a monthly salary (type int). Your class should have a constructor that initializes the three data members. Provide a set and a get function for each data member. If the monthly salary is not positive, set it to 0. Write a test program that demonstrates class Employee’s capabilities. Create two Employee objects and display each object’s yearly salary. Then give each Employee a 10 percent raise and display each Employee’s yearly salary again.
1- Create a hierarchy of Java classes as follows: MyRectangle is_a MyShape; MyOval is a MyShape. Class MyPoint: Class MyPoint is used by class MyShape to define the reference point, p(x, y), of the Java display coordinate system, as well as by all subclasses in the class hierarchy to define the points stipulated in the subclass definition. The class utilizes a color of enum reference type MyColor, and includes appropriate class constructors and methods. The class also includes draw and toString methods, as well as methods that perform point related operations, including but not limited to, shift of point position, distance to the origin and to another point, angle [in degrees] with the x-axis of the line extending from this point to another point. Enum MyColor: Enum MyColor is used by class MyShape and all subclasses in the class hierarchy to define the colors of the shapes. The enum reference type defines a set of constant colors by their red, green, blue, and opacity, components,…
4. Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four data members-a part number (type string), a part description (type string), a quantity of the item being purchased (type int) and a price per item (type int). Your dlass should have a constructor that initializes the four data members. A constructor that receives multiple arguments is defined with the form: ClassName( TypeName1 parameterName1, TypeName2 parameterName2, .) Provide a set and a get function for each data member. In addition, provide a member function named getinvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as an int value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0. Write a class program according to the main.cpp program given below. #include #include invoice #include…
2019 AP® COMPUTER SCIENCE A FREE-RESPONSE QUESTIONS 2. This question involves the implementation of a fitness tracking system that is represented by the StepTracker class. A StepTracker object is created with a parameter that defines the minimum number of steps that must be taken for a day to be considered active. The StepTracker class provides a constructor and the following methods. addDailySteps, which accumulates information about steps, in readings taken once per day activeDays, which returns the number of active days averageSteps, which returns the average number of steps per day, calculated by dividing the total number of steps taken by the number of days tracked The following table contains a sample code execution sequence and the corresponding results. Statements and Expressions Value Returned Comment (blank if no value) StepTracker tr StepTracker(10000); Days with at least 10,000 steps are considered active. Assume that the parameter is positive. new tr.activeDays () ; No…
Imagine a publishing company that markets its works. Create a class publication that stores the title (a string), author (string), pages (int), pulicationDate (string) and price (type float) of a publication. There should be two constructor i.e. default and parameterized. The default Constructor should initialize the data members to 0 or 0.0 or “” if integers, floating point or string respectively. The parameterized constructor should assign user defined values to the data members. The default constructor should be inline while the parameterized constructor should not be inline. There should be an input/get function to input the values to the data members and a Print() to display the contents of the class variables/datamembers. Create two objects of the class named book, and tape. The book should be created with default constructor, while tape with parameterized constructor. Call input/get for book object only. Then call Print() for both the objects to display the contents. Mention…
Create a class MyTime which has the datamembers as follows: 1. hour: integer (1 to 12)2. minute: integer (0 to 59)3. second: integer (0 to 59)4. pm: bool variable. True means PM time and false means AM time. Implement a default constructor, a parameterized constructor and a copy constructor. Write set and get functions for all the four members of the class. Overload these operators: 1. Extraction operator >> : Prompt the user for hours, minutes, seconds and for am/pm and initialize the structure. Left operand istream object and right operand MyTime2. Assignment = : Assign the right object to the left object. Both operands are of type MyTime.3. Insertion << : Print the time in the format HH:MM SS PM. Left operand of type ostream and right operand of type MyTime. this in c++.
A complex number has the form a+bi , can be expressed as the ordered pair of real numbers (a,b). The class represents the real and imaginary parts as double precision values. Provide a constructor that enables an object of this class to be initialized when it is instantiated. The constructor should contain default values. Provide Public member functions for each of the following arithmetic’s functions (addition – subtraction – multiplication – division), a complex absolute value operation, printing the number in the form (a,b), printing the real part , printing the imaginary part and final overload the == operator to allow comparisons of two complex numbers. Include any additional operations that you think would be useful for a complex number class( (c++) in three programs header file , implementation file and client file ,
