(Payroll System Modification) Modify the payroll system of Figs. 20.9–20.17 to includeprivate data member birthDate in class Employee. Use class Date from Figs. 18.6–18.7 to representan employee’s birthday. Assume that payroll is processed once per month. Create a vector of Employee references to store the various employee objects. In a loop, calculate the payroll for each Employee (polymorphically), and add a $100.00 bonus to the person’s payroll amount if the currentmonth is the month in which the Employee’s birthday occurs.
(CP6) Write a function that is passed an array of structs and performs calculations. The function should locate the highest gpa from a group of students. The function is passed the array of structs, the first element to be searched, and the last element to be searched. The return value of the function is the highest gpa in the search range.
struct data{ string name; double gpa;};
double highestGpa( data [ ], int, int );
data [ ] - array of structs to search
int - first element to be searched
int - last element to be searched
return - highest gpa from group
(Enhancing Class Date) Modify the Date class of Figs. 17.13–17.14 to perform error checking on the initializer values for data members month, day and year. Also, provide a member functionnextDay to increment the day by one. Write a program that tests function nextDay in a loop thatprints the date during each iteration to illustrate that nextDay works correctly. Be sure to test thefollowing cases:a) Incrementing into the next month.b) Incrementing into the next year.

- (Modifying Class GradeBook) Modify class GradeBook (Figs. 16.11–16.12) as follows:a) Include a second string data member that represents the course instructor’s name.b) Provide a set function to change the instructor’s name and a get function to retrieve it.c) Modify the constructor to specify course name and instructor name parameters.d) Modify function displayMessage to output the welcome message and course name,then the string "This course is presented by: " followed by the instructor’s name.Use your modified class in a test program that demonstrates the class’s new capabilities.arrow_forward[In c#] Write a class with name Arrays .

- (Enhancing Class Time) Modify the Time class of Figs. 17.4–17.5 to include a tick memberfunction that increments the time stored in a Time object by one second. Write a program that teststhe tick member function in a loop that prints the time in standard format during each iterationof the loop to illustrate that the tick member function works correctly. Be sure to test the followingcases:a) Incrementing into the next minute.b) Incrementing into the next hour.c) Incrementing into the next day (i.e., 11:59:59 PM to 12:00:00 AM).arrow_forward(USING PYTHON) create a function create employee_objects that takes a list of data as input and returns back a list with each element as an object that belongs to class Employee def create employee_objects (data): #start of code # end of code employees_list = create employee_objects (employees_data) Expected output: 29arrow_forward(Check test scores) The answers to a true-false test are as follows: T T F F T. Given a two-dimensional answer array, in which each row corresponds to the answers provided on one test, write a function that accepts the two-dimensional array and number of tests as parameters and returns a one-dimensional array containing the grades for each test. (Each question is worth 5 points so that the maximum possible grade is 25.) Test your function with the following data: int score = 0;arrow_forward
- (Polymorphic Banking Program Using Account Hierarchy) Develop a polymorphic banking program using the Account hierarchy created in Exercise 19.10. Create a vector of Accountpointers to SavingsAccount and CheckingAccount objects. For each Account in the vector, allowthe user to specify an amount of money to withdraw from the Account using member function debit and an amount of money to deposit into the Account using member function credit. As youprocess each Account, determine its type. If an Account is a SavingsAccount, calculate the amountof interest owed to the Account using member function calculateInterest, then add the interestto the account balance using member function credit. After processing an Account, print the updated account balance obtained by invoking base-class member function getBalance.arrow_forward(FRP7) Write a function that reads data from a file. The file has already been opened and verified. The data should be saved in the array of type ship. The size of the array is passed in the int parameter and the number of records read is return in the last parameter, by reference. The file should be read until end of file has been reached or the array is full. struct ship{ string shipCaptain; string shipName; }; The function prototype isvoid readFile( ifstream&, ship[ ], int, int& ); ifstream - The already open file ship[ ] - array of structs where the data from the file will be stored. int - the size of the array. int& - the number of records read from the file. This value is set by the function before returning return- the number of records read from the file, returned by the function. The amount of data in the file is unknown but there is no bad data. The file format is the shipsName followed by the shipsCaptiain . Example: MillenniumFalcon HansSoloarrow_forward(JAVA) Create a two-dimensional array of type double to contain the three different SD Marks (JD521, PRG521, and IP521) for six different students. A single array of type String must be used to store the student names (Maxwell, Carl, Gerhard, Paul, James, and Cena). Allow a user to enter in a number, ranging from 1 to 6, which will represent the student position in the table MCSD max and present the marks for each respecting module. The program can only stop when the user enter a number greater than 6. Printout the student name including the JD521, PRG521, and IP521 max, the total of marks and the average of all marks. Use a condition statement to decide that the student has passed or not (Pass rate is 70). The programming language is java Student name JD521 PRG521 IPG521 Maxwell 80 65 70 Carl 95 70 65 Gerhard 87 80 73 Paul 65 45 60 James 45 87 65arrow_forward
- Question 4: (Find the minimum value in an array) Write a program that include arecursive function “recursiveMinimum” that takes an integer array and the array size asarguments and returns the smallest element of the array. The function should stopprocessing and return when it receives an array of one element.arrow_forward(Time Class Modification) It would be perfectly reasonable for the Time class of Figs. 17.4–17.5 to represent the time internally as the number of seconds since midnight rather than the threeinteger values hour, minute and second. Clients could use the same public methods and get thesame results. Modify the Time class of Fig. 17.4 to implement the time as the number of secondssince midnight and show that there is no visible change in functionality to the clients of the class.[Note: This exercise nicely demonstrates the virtues of implementation hiding.]arrow_forward(Set and Get Functions) Explain why a class might provide a set function and a get functionfor a data member.arrow_forward
