- Design a struct personalinfo with components id, and name of type string. Design a class student with private data member's person (struct variable of type personalInfo), number Of Courses (of type integer), average (of type float), and marks[] an array of student's marks of type integer. The class also has the member functions ser( ), getPerson(), print(), findAverage(), getAverage(), and a parameterized constructor with default value 1 for the number of courses. Implement the member functions of the class student. The member function findAverage() is used to calculate the average mark for each student. I Write a driver that does the following: Declares the array section[ ] of objects of student type. Reads the number of students. Reads information for each student from the file student.txt. Calls the user-defined function int maxAverageIndex(int, student []) Prints the id and name of the student with the maximum average.

Hourly Employee provide the setters and getters of your data members provide call to parent contructors earnings is computed by having the product of the total number of hours worked and the rate. but if the number of hours worked exceeds 40, the rate increases to 150% of the current rate. (ex. rate=200; 150% = 300) override the toString() and equals() methods Note:Class Person is already loaded in this activity. No need to add the class in your code.In c++Create a lecturer class with member-data name (name) and department (department). For the Lecturer class, write constructors, get & set methods, and the toString () method, which returns the textual description of the object. Write a Lecture class with data member:- subject (discipline)- weekday (day of the week when it takes place)- hour (start time, integer)- online (boolean value, whether remote or not)- lecturer (object of class Lecturer)For the Lecture class, write:- constructors- get & set methods- method isItMorning (), returning a Boolean value, the result of checking whether the lecture starts at 7-11- give a new implementation of the toString () method so that it returns the text description of the Lecture objectIn the test function main ()1. Create objects of both classes and illustrate the use of all possible methods for them.2. Create an array of Lecture objects and display it on the screen and in a file.
- : Imagine you have a call center with three levels of employees: respondent, manager,and director. An incoming telephone call must be first allocated to a respondent who is free. If therespondent can't handle the call, he or she must escalate the call to a manager. If the manager is notfree or not able to handle it, then the call should be escalated to a director. Design the classes anddata structures for this problem. Implement a method dispatchCall () which assigns a call tothe first available employee.Consider this scenario, a mehtod in some class needs to access a data field in another class, here are two possible implementations: public class Process { /* * Check if student qualifies for financial help */ void check(Student student) { //.... } /* * Check if student qualifies for financial help */ void check(double studentGPA) { //.... }} In class Process, which check method you think is better, why? In other words, should we pass the object to the method or just the data member it needs? Disucuss the Pros and Cons of each approach (if any). Assume class Student has a mehod called getGPA( ).In c++, Consider a class BankAccount that has Two attributes i.e. accountID and balance and A function named balanceInquiry() to get information about the current amount in the account Derive two classes from the BankAccount class i.e. CurrentAccount and the SavingsAccount. Both classes (CurrentAccount and SavingsAccount) inherit all attributes/behaviors from the BankAccount class. In addition, followings are required to be the part of both classes Appropriate constructors to initialize data fields of base class A function named amountWithdrawn(amount) to withdraw certain amount while taken into account the following conditionso While withdrawing from current account, the minimum balance should not decrease Rs. 5000o While withdrawing from savings account, the minimum balance should not decrease Rs. 10,000 amountDeposit(amount) to deposit amount in the account In the main() function, create instances of derived classes (i.e. CurrentAccount and SavingsAccount) and invoke their…
- Write a function with the interface doRandomWalk(nstep,startPosition), that takes the number of steps nstep for a random walk and the startPosition of the random walk on a straight line, and returns the location of the final step of the random walker. Problem Part B Now, write another function with the interface simulateRandomWalk(nsim,nstep,startPosition) that simulates nsim number of random-walks, each of which contains nstep steps and starts at startPosition. Then, this function calls doRandomWalk() repeatedly for nsim times and finally returns a vector of size nsimcontaining final locations of all of the nsim simulated random-walks. Problem Part C Now write a script that plots the output of simulateRandomWalk() for nsimnstepstartPosition===1000010−10 The resulting plot should look like the following, How do you interpret this result? How can uniformly-distributed random final steps end up having a Gaussian bell-shape distribution.Design a class named LinearEquation for a 2x2 system of linear equations: ax + by = ecx + dy = f x = (ed - bf)/(ad - bc ) y = (af - ec)/(ad-bc) The class contains:■ The private data fields a, b, c, d, e, and f with get methods.■ A constructor with the arguments for a, b, c, d, e, and f.■ Six get methods for a, b, c, d, e, and f.■ A method named isSolvable() that returns true if is not 0.■ The methods getX() and getY() that return the solution for the equation.Draw the UML diagram for the class, and then implement the class. Write a test program that prompts the user to enter a, b, c, d, e, and f and displays the result. If is 0, report that “The equation has no solution.”Please help me design a SimulationProject.cpp in C++. THANK YOU! For this assignment, we will simulate boarding procedures for Airworthy Airlines. The Airline's current procedure is as follows: pre-board in the following order: families with young children or people who need help (e.g., wheelchair) first class and/or business class passengers elite passengers (frequent fliers) and those passengers seated in exit rows conduct general boarding in reverse, from the back of the plane to the front in the following order: rows 23-26 rows 17-22 rows 11-16 rows 5-10 Airworthy is considering revising their boarding procedure such that general boarding is done randomly, meaning the first passenger in line for general boarding is the first passenger to board (i.e., general boarding passengers all have the same priority). Airworthy suspects this random general boarding method will improve the flow of passengers, getting them on board and seated more quickly. It is also less labor-intensive…
