4.5 An Example of Patient EER Schema Consider the following information about a patient database: A patient is identified by patient id, and admission date. • A patient must be either an Emergency patient or a resident patient. We must record the checkback date for Emergency patient. Only resident patient is assigned to one room. Room has a unique number, degree, and floor number. • For each room there are a number of beds each of which has a bed number, specification. If a room is deleted, you need not keep track of its beds any longer. Both emergency patient and resident are cared for by a responsible Doctor. Doctor is identified by Doctor number. For each Doctor, the name, several specialty, and years of experience must be recorded. Doctors prescribe medicine for patients. Medicine is identified by trade name that has scientific name and formula. The medicine depends on another medicine to be taking before. • A doctor could prescribe one or more drugs for several patients, and a patient could obtain prescriptions from several doctors. Each prescription has a date and a quantity of medicine. Draw an ER/EER diagram that captures the above information.

23.16 LAB: Find student with highest GPA Complete the Course class by implementing the FindHighestStudent() 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) ------ course.cpp ---- #include <iostream>#include "Course.h"using namespace std; Student Course::FindStudentHighestGpa() {/* Type your code here */} void Course::AddStudent(Student s) {roster.push_back(s);} ----- course.h…
1. Define a Matrix class to represent a square 2-D grid of int numbers. Include a constructor that takes one required int argument (for the number of rows and columns, which is the same since the matrix is square) and initializes all values to 0. Store the values in a self.data attribute. For example, Matrix(3) would initialize self.data as a list of lists of ints representing a 2-D grid with 3 rows and 3 columns. 2. Define a Matrix __str__(self) -> str method that would produce a string representation of a Matrix object. 3. Write a Matrix method set_value(self, i: int, j: int, val: int) that assigns val to the matrix value in the i-th row and j-th column of self.data. 4. Write a method get_diagonal(self) -> List[int] that returns the list of diagonal elements (from the top-left element to the bottom-right element). For example, if the matrix contains:
Using Classes Write a program that inputs, processes, and outputs a set of student records organized as a vector of class StudentRec objects. Using the attached code as a "model", write a program where each student record is constructed using the class StudentRec. The variables in this case are "private" and the functions are "public." Note: only the first_name and last_name variables will require "getter" functions that return the name in all caps: get_first_name_upper() and get_last_name_upper() functions. Your class declaration section should look something like this: class StudentRec { private: string last_name = ""; // Last name string first_name = ""; // First name int year_grad = 0; // Year expected to graduate float gpa = 0.0; // Current gpa public: void set_last_name(string last_name_param); string get_last_name() const; string get_last_name_upper() const; // the rest of the "setter" and "getter"…
A) Write a program and define a class of Student. Student has these attributes :Age (an int)FirstName (a string)LastName (a string)Social Security Number (an int)Add the default constructor Add a second constructor that sets the attributes of the class Add the copy constructor that creates a copy of the student and override assignment operator. B) Create a vector of 100 students. Use a for loop to fill the vector . C) Add a function to your program that sorts the vector using selection sort in ascending order . D) Add a function to your program that searches the vector using binary search to find the youngest student .
Define the function print_trophic_class_summary(tli3_values) that accepts a list of trophic level index values and prints a summary outlining the number of lakes in each trophic classification, in order from highest trophic classification to lowest. See the examples for the required format. Notes: Your function must print the summary, not return it. In each state line, the initial number should be formatted with width 3. (Hint: :3 will be helpful) All possible states must be included in the output, even states with zero lakes. The following list will be helpful: ['Hypertrophic', 'Supertrophic', 'Eutrophic', 'Mesotrophic', 'Oligotrophic', 'Microtrophic', 'Ultra-microtrophic'] You must include and use one of your number_in_trophic_class functions (take your pick!), plus your trophic_class function. Basically, you can start with your answer to Question 5 or 6 and add your print_trophic_class_summary function definition after your previous definitions. For example: Test Result…
(PYTHON) a) get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary. (Suppose we want to know the total number of cases reported on each date, so use x = 0.) >>> result, total_cases = get_total_cases(database, 0) >>> display_dict(result) 2021-05-19: 8 2021-05-20: 2 2021-05-21: 1 2021-05-22: 1 >>> print(total_cases) 12
Define a function deleteProp that has 2 parameters: obj an object to update keyName, a string - a key name to delete from the object deleteProp should delete the property with the key of keyName. deleteProp should return the object that was passed in (not a “copy” or different object with the same key/value pairs) example const wallet = { color: 'Black', hasCash: true } deleteProp(wallet, 'color'); => { hasCash: true } const house = { sqFt: 1500, isOccupied: true } deleteProp(house, 'isOccupied'); // => { sqFt: 2000 } javascript

Create a class Department with attributes DName, DID, a dynamic listDTeachers of type string.Write accessors and mutators for all data membersand show function to show all data members.Create nullaryand parameterized constructors to initialize the data members.Also write a copy constructor for Department class.In main() create a dynamic array of departments, Use loop to create four objects in the dynamic array. All the even indexed objects should be created with nullary constructors and thencall the accessors and mutators to initializethe objects while, all the odd indexed objects should be initialized using parameterized constructors. Create four copy objects from array using copy constructors.Call the show function to show the four objects.
c++ Assume that we have a class called department. One of the data members of the department class is a pointer to a dynamically allocated array of faculty objects named faculty_array, that has been declared like this: faculty* faculty_array = nullptr; Write a complete member function definition for a destructor for this department class. The destructor should deallocate any dynamic storage pointed to by the pointer faculty_array.
Description Java you will create a backend class called SortableSet. A set, in computer science, is an unordered collection of unique objects. In our SortableSet, all of the objects in the set will also be immutable at the set level. This means that even if the data class used to create objects is not immutable, once they are in the set they are. We do this by making a deep copy of any objects being added to the set or returned from the set. The objects stored in the SortableSet must implement an interface called Sortable that provides a numeric sorting key and a deep copy method. SortableSet also takes advantage of two custom exception classes: DuplicateException and InvalidKeyException. Finally, the "sortable" part of SortableSet is implemented by a getSortedList method that makes a deep copy of every object in the set, saves them to an array, and then sorts them based on each object's sorting key. The sort algorithm used is a recursive radix sort modified to work with objects.…
