3. Dependency Inversion Principle: high-level modules should not depend upon low level modules. Both should depend upon abstraction. The following code is an implementation of a login function for MySocialNetwork, but it violates the Dependency Inversion Principle. a. Explain why the code violates the Dependency Inversion Principle b. Rewrite the code to make it conform with the principle public class My HCMIU_ Email { public void loginWithStudentID(String username, String password) { /* .....*/ } } public class MySocialNetwork { private My_HCMIU_Email loginService; public void SetLoginService (My_HCMIU_Email value) { loginService = value; } public bool login(String username, String password) { return loginService.loginWithStudentID(username, password); }

SUBJECT: OOPPROGRAMMING LANGUAGE: C++ ADD SS OF OUTPUT TOO. Create a class Student with attributes StudentName, Enrollment, semester, section, course MarksObtained and Grade. Write appropriate constructors, get and set functions for data members. The data member grade is automatically calculated based on marks obtained out of 100 for each course.
5. Write a function logisticClassify that takes in the m feature values for the n data points as a np-array with dimensions (n,m) and the weight vector w as a np-array with dimension (m+1) (with b as the final element of w). The function returns the 0/1 label for each data point as a np-array of dimension (n). Use the following syntax: classLabels=logisticClassify(x,w)
Using c++ Find student with highest GPA Complete the Course class by implementing the FindStudentHighestGpa() member function, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: Class Course represents a course, which contains a vector of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three private data members: first name, last name, and GPA. (Hint: GetGPA() returns a student's GPA.) Note: For testing purposes, different student values will be used. Ex. For the following students: Henry Nguyen 3.5 Brenda Stern 2.0 Lynda Robison 3.2 Sonya King 3.9 the output is: Top student: Sonya King (GPA: 3.9) #include <iostream>#include "Course.h"using namespace std; Student Course::FindStudentHighestGpa() { /* Type your code here */} void Course::AddStudent(Student s) { roster.push_back(s);}

Create a Pair class in C++ with the members x, y and also overload the + operator to add the values of x separately and the values of y separately for two objects of the Pair class. Also, write a parameterized constructor for the class. Public Members: int x, int y Function: Overload the + operator. Constructor: Parameterized.
Implement a nested class composition relationship between any two class types from the following list: Advisor Вook Classroom Department Friend Grade School Student Teacher Tutor Write all necessary code for both classes to demonstrate a nested composition relationship including the following: a. one encapsulated data member for each class b. inline default constructor using constructor delegation for each class c. inline one-parameter constructor for each class d. inline accessors for all data members e. inline mutators for all data members
A C++ assignment Implement the GradedActivity class. Copying from the pdfs is fine. Create a new class Assignment which is derived from GradedActivity. It should have three private member ints for 3 different parts of an assignment score: functionality (max 50 points), efficiency (max 25 points), and style (max 25 points). Create member function set() in Assignment which takes three parameter ints and sets the member variables. It should also set its score member, which is inherited from GradedActivity, using the setScore() function, to functionality + efficiency + style. Signature: void Assignment::set(int, int, int) Create a main program which instantiates an Assignment, asks the user for its functionality, efficiency, and style scores, and prints out the score and letter grade for the assignment. ___________________________________________________ Examples from the pdfs: d PassFailExam::set(int q, int m, int p) { double numericScore, pointsEach; numQuestions =…
