Suppose a problem design requires storing a collection of objects. Suppose further that the objects will have varying behavior, but they will be related through inheritance. The base class for all the objects has declared some virtual functions and the behavior of the derived classes varies when that function is invoked. Which of the following statements are true? I.If the objects are managed using for example, an array, the array should store pointers to the objects, not the objects themselves II.When the objects are passed as parameters to other functions, they should be passed by reference III.Using pointers to the objects as a way to manipulate them will enable polymorphic behavior I, II, III OI, II

For this problem you need the Employee class again. Write another main function to answer the following questions. Only submit the main function for this problem. Create an Employee object using the constructor with parameters. Declare an Employee pointer and make it point to the Employee object created in part (i). Use the pointer to call the print() method of the object. Dynamically create an Employee object using the constructor with parameters and make the Employee pointer point to this newly created dynamic object. Use the pointer to set the name of the Employee to some other name. Use the pointer to call the print function. Use the pointer to allocate a dynamic array of three employees and populate the array with Employee objects. What happens to the previously allocated memory for the Employee in part (iv)? Use a for loop to print the Employees objects in the dynamic array constructed in part (vii). Delete the pointer and set it to point to NULL. Explain what does this step…
Design the PartnerAssignment class that contains: Two String arrays as attributes. A constructor which takes the text file name as parameter and fill the first array withthe first row of names and the second array with the second row of names in the file. A method checkPartnerAssignment that determines if the assignment of partners iscorrect or incorrect and this method returns a string value
Using the scenario of Object oriented programming oop Q.A designer in 3D graphics company wants to design a matrix as a two-dimensional array. The size of 2D array could be the last two digit of arid number. Initially he creates a class matrix that provides the member function to check that no array index is out of bounds. Make the member data in the matrix class a 10-by-10 array. A constructor should allow the programmer to specify the actual dimensions of the matrix (provided they’re less than 10 by 10). The member functions that access data in the matrix will now need two index numbers: one for each dimension of the array. Here’s what a fragment of a main() program that operates on such a class might look like: If my Arid Number is 20-Arid-254 then: // in case of zero consider next digit matrix m1(5, 4); // define a matrix object int temp = 12345; // define an int value m1.putel(7, 4, temp); // insert value of temp into matrix at 7,4 temp = m1.getel(7, 4); // obtain value…

Write a C# program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate. Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string)

Question 1 Write a Python class named Histogram that keeps track of how many times each unique element in a given sequence occurs. This class will implement the following interface: • Histogram( sequence ) will create a histogram of all elements occurring in the given sequence. This class cannot use the dict or collections.Counter types to create instance or class variables in order to implement the following specifications! If it does, the grade for your solution will automatically be zero! However, in some cases, your code will have to return dictionaries. So note the difference between the two specifications! • get( element-None, default-e ) will return how many times given element occurs in the histogram. If no element is specified, then the get () function will retum a dictionary where keys are elements and values are number of times a given element occurs in the sequence provided to the initializer. For example, given h - Histogram( "aaabbc" ) then h.get( "b" ) should return 2,…
Write in C++ a class Restaurants to manage a vector of Restaurant objects. The class Restaurants should have: • A private vector to store Restaurant objects • A public add method to add a Restaurant to the Restaurants • A public average_max_rating method that returns the average of max ratings of the restaurants. • A public get_max method that returns the Restaurant that has highest max rating.
Design a class to display the schedule of buses inlellore Bustand. The class can have its own member variable like bus_no, sro, dest, time, traveltime, laneno. Create an array of objects in the main function. Pertorm the following tasks. SearchFunction () - Takes busno has input and perfroms a soarch with all objects. If found display all variable details of the class like bus no, src, dest, time traveltime, laneno, traveltype. b. SortFunction ()-Takes the input of sorting type (TM- time based, BN- Bus no based). Sort and display the records.
