Create a class called Complex that includes two pieces of information as data members: the real part (double), and the imaginary part (double). The default value of these data members is 0. Write down member functions set and get for each of these data members. Further, write a member function displayComplex which displays the complex number with real part 3 and imaginary part 4 as "3+4i". Note. if the real part is 3 and the imaginary part is -4, then you want the displayed string to be "3-4i" rather than "3+-4i". Writera test program that demonstrates your class abilities. In addition, draw a class diagram for your class.

Create an employee class, basing it on previous lab. The member data should comprise an int for storing the employee number, a string for storing the name and a float for storing the employee’s salary. Member functions should allow the user to enter this data and display it. Write a main () that allows the user to enter data for three employees and display it do it by using scope resolution operator and pointer object.
Create a class called Bill that a hardware store might use to represent a bill for an item sold at the store. A Bill should include three data members—a part number (type string), a quantity of the item being purchased (type int) and a price per item (type double). Your class should have a constructor that initializes the three data members. Provide a set and a get function for each data member. In addition, provide a member function named getBillAmount that calculates the bill 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 C++ test program that demonstrates class Bill’s capabilities.
Create a class called Time that has separate int member data for hours, minutes, and seconds. One constructor should initialize this data to 0, and another should initialize it to fixed values. Another member function should display it, in 11:59:59 format. The final member function should add two objects of type time passed as arguments.
Write a class Travel having two private data members (distanceCovered , Time) The class has three constructors which are • having no parameter – for setting values to zero or null. • having two parameters for assigning values to both data members. • Overload the above constructor and use this keyword to set the values of data members. • Provide getters/setters for data members. • A function which calculates and display speed of traveling. • Write a function show() displays values. Write test Application that demonstrates the Run class by calling all the three constructors and method, creating a Create Travel objects, and then display the traveling with speed. Calculate highest speed. Programming language : java
Problem: Create a Fraction class with two private positive integer member variables numerator and denominator, one constructor with two integer parameters num and den with default values 0 and 1, one display function that print out a fraction in the format numerator/denominator in the proper form such as 2/3 or ½ . Note: 2/4 should be displayed as ½.
*I am using the program mindtap Chapter 9 defined the struct studentType to implement the basic properties of a student. Define the class studentType with the same components as the struct studentType, and add member functions to manipulate the data members. (Note that the data members of the class studentType must be private.) Write a program to illustrate how to use the class studentType. Struct studentType: struct studentType { string firstName; string lastName; char courseGrade; int testScore; int programmingScore; double GPA; }; An example of the program is shown below: Name: Sara Spilner Grade: A Test score: 89 Programming score: 92 GPA: 3.57 ***************

Rewrite the calculator program using a class called calculator. Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division) Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as : A member function to perform the addition and return the result A member function to perform the subtraction and return the result A member function to perform the multiplication and return the result A member function to perform the division and return the result
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.
Create three classes Person, Professor and Student. The class Person should have data members name and age. The classes Professor and Student should be inherited from the class Person. The class Professor should have two integer members: publications and cur_id. There will be two member functions: getdata and putdata. The function getdata should get the input from the user, namely, the name, age and publications of the professor. The function putdata should print the name, age, publications and the cur_id of the professor. The class Student should have two data members: marks, which is an array of size 8 and cur_id. It has two member functions: getdata and putdata. The function getdata should get the input from the user, namely, the name, age, and the marks of the student in 8 subjects. The function putdata should print the name, age, sum of the marks and the cur_id of the student. For each object that you would create for either the Professor or the Student class, sequential ids…
In C++, Create a class called Date that includes three data members: amonth(type int), a day(type int), and a year(type int). The Date class willhave a constructor with three parameters to initialize the three data members.You may assume the values provided for the year and day are correct, but makesure that the month value is in the range 1-12; if it isn't, set the month to1. Provide set and get functions for each data member. Provide a memberfunction displayDate that displays the date in format MM/DD/YYYY.Write a test program that prompts the user to input the month, the day,and the year and uses your Date class to output the formatted date.
Create a class called Employee that includes four pieces of information as data members — a first name (type string), a middle name (type string) , a last name (type string)and a monthly salary (type int). Your class should have a constructor that initializes the four 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.
