C++ Dynamic Programs Hoskins College offers both curriculum and continuing education courses. Write a program that dynamically tracks these courses using an array of object pointers. Every course (both curriculum and continuing education) has a course id, title, room number, and number of contact hours. A curriculum course has credit hours and tuition rate. Tuition is calculated by multiplying the course's credit hours by tuition rate. A continuing education course has a flat fee (cost). Implement a show() function in every class that displays the data in the object. Part A: Create an inheritance-based collection of classes to represent these different courses. Include code in main to test your work by instantiating objects of the two derived classes. Part B: Modify your program. Remove the objects you created in main to test the classes. Modify the base class so that show() becomes a virtual class. In main, create a single array capable of holding pointers to objects of both…

Language: JAVA Script Your company is giving every employee earning less than $50,000 a 10% raise! *Write a function 'employeeRaises(peopleObj)' that takes an array of objects s containing employee names and their salaries and returns an array containing the employees that need raises, along with their new salaries. Example: employees [ {name: "Alice", salary: 80000}, {name: "Bob", salary: 48000 }, {name: "Carol", salary: 60000}, {name: "Dan", salary: 78000}, {name: "Ellen", salary: 100000}, console.log(employeeRaises (employees) ); // [ { name: 'Bob', salary: 44000 } ] funcation emplyeeRaises(employees){ |// Your code here} /****DO NOT MODIFY ANYTHING UNDER THIS LINE****/ try{| module.exports = employeeRaises;}catch (e) {|module.exports=null;}
In C++ Create a class called Pencil. Pencil has a type. Create another class called Customer. The customer class should have a ID number, array (using pointers) called purchases, and a Pencil variable. Make sure to create the purchases array in the constructor. Create a function to fill in purchase amount. Create a way to output all the information about a customer, including all the details about their type of pencil.
Topical Information Use C++. This lab will help you practice with dynamic memory (NOT mixed with classes). Program Information Heat flow through a rod can be simulated fairly easily in a computer program. We can simulate the rod using an array of temperatures. The rod begins all at the same temperature (user determined), but holding some position(s) of the rod at constant temperature (holding a match or ice cube to the rod) provides a [set of] heat source(s) (or sink(s)). To update the temperature at each time step (second?), you take the average of the positions on each side from the previous time step (and at the current position). For instance, if the following was the initial state of the rod: +------+------+------+------+------+------+------+------+ | 10 | 10 | 10 | 10 | 10 | 10 | 10 | 10 | +------+------+------+------+------+------+------+------+ And then the user specifies that there is a heat source at the left end of 100 degrees:…

Now create a public member functions void getID(), void getName() and getCGPA() and finally to display all the data members, create a function void display(). In the main(), create an array of student class, size of the array should be taken from user at run time and call all the functions defined in the class. Sample Output: Student 1 Enter ID: 1 Enter Name: Ali Enter CGPA: 2.5 Student 2 Enter ID: 2 Enter Name: Ahmed Enter CGPA: 2.9 Student 3 Enter ID: 3 Enter Name: Zain Enter CGPA: 3.4 Student 1 informationID: 1 Name: Ali CGPA: 2.5 Student 2 information ID: 2 Name: Ahmed CGPA: 2.9 Student 3 information ID: 3 Name: Zain CGPA: 3.4
8.9 LAB: Car value (classes) Complete the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information. Ex: If the input is: 2011 18000 2018 where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs: Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770 Note: print_info() should use three spaces for indentation.

In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…
