3 Objects s1, s2 and s3 of Student type are declared and members of the three objects are set by prompting the user from the set() function. The details of all the objects are displayed using the print() function.
Code:
#include<iostream>
#include<iomanip>
#define FIX(x) std::fixed
<<std::setprecision(1)<<(x)/*fixes precision of GPA to
1 so that only 1 number is printed after decimal*/
using namespace std;
class Student
{
//member variables
string first_name;
string last_name;
int id;
double gpa;
string major;
public:
//member functions
void set()
{
//prompting user to enter input for
all the member variables
cout<<"First Name:
";cin>>first_name;
cout<<"Last Name:
";cin>>last_name;
cout<<"ID:
";cin>>id;
cout<<"GPA:
";cin>>gpa;
cout<<"Major:
";cin>>major;
}
void print()
{
//Showing summary in a user
readable form
cout << first_name << "
" << last_name << " (" << id << ")"
<< " graduated with a " << FIX(gpa) << " GPA in "
<< major << "." << endl;
}
};
int main()
{
Student s1;//object 1 of Student type
Student s2;//object 2 of Student type
Student s3;//object 3 of Student type

2- Write a program that has a Person class, a Student class, that is derived from Person, and a Faculty class, derived from Person as well, with the following specifications: The Person class has the following members: a. An integer private member variable named SSN. b. Two string protected member variables named firstName and lastName. C. An integer protected member variable named age. d. A constructor that takes SSN, first name, last name, and age as parameters. e. A constructor...
C++ In the code cell below, define a class named Student with an integer id and a string name. This class should have a constructor that takes two arguments: one for the id and the other for the name. Then Create another class named CollegeStudent that publicly inherits from Student. This class should have a protected member named major. It should also have a constructor that takes three arguments: id, name, and major. This constructor should delegate initializing the id...
This is a simple C++ class using inheritance, I have trouble getting the program to work. I would also like to add ENUM function to the class TeachingAssistant(Derived class) which is a subclass of Student(Derived Class) which is also a subclass of CourseMember(Base Class). The TeachingAssistant class uses an enum (a user-defined data type) to keep track of the specific role the TA has: enum ta_role {LAB_ASSISTANT, LECTURE_ASSISTANT, BOTH}; You may assume for initialization purposes that the default role is...
2. Create a class named Student that contains the following » idStudent. The idStudent is an int variable that holds the student's matric number. name. The name field references a String object holds the student's name. . major. The major field references a String object holds the student's major. . classification. The classification field references a String object holds the student's classification level (bongsu, kecil, muda, sulung) . Constructor should accept the student's matric number, name, major and classification as...
A class allows a group of one or more member objects to have a series of common characteristics and functions. Create a class (student) that contains the member characteristics: Student ID (string) Student Last Name (string) Student First Name (string) GPA (float) Number of enrolled classes (integer) The class functions are: setID (string passed to function to set Student ID) setLastName (string passed to function to set Student Last Name) setFirstName (string passed to function to set Student First Name)...
Create an abstract Student class for Parker University. The class contains fields for student ID number, last name, and annual tuition. Include a constructor that requires parameters for the ID number and name. Include get and set methods for each field; the setTuition() method is abstract. Create three Student subclasses named UndergraduateStudent, GraduateStudent, and StudentAtLarge, each with a unique setTuition() method. Tuition for an UndergraduateStudent is $4,000 per semester, tuition for a GraduateStudent is $6,000 per semester, and tuition for...
you must implement public class Student by following the instructions as follows exactly. You may reference Chapter 7 for the similar examples to get the ideas and concepts. Each student must have the following 5 attributes (i.e., instance variables): private String studentID ; // student’s ID such as 1 private String lastName ; // student’s last name such as Doe private String firstName ; // student’s first name such as John private double gpa...
PART I: Create an abstract Java class named “Student” in a package named “STUDENTS”. This class has 4 attributes: (1) student ID: protected, an integer of 10 digits (2) student name: protected (3) student group code: protected, an integer (1 for undergraduates, 2 for graduate students) (4) student major: protected (e.g.: Business, Computer Sciences, Engineering) Class Student declaration provides a default constructor, get-methods and set-methods for the attributes, a public abstract method (displayStudentData()). PART II: Create a Java class named...
Write a C++ program that includes the following: Define the class Student in the header file Student.h. #ifndef STUDENT_H #define STUDENT_H #include <string> #include <iostream> using namespace std; class Student { public: // Default constructor Student() { } // Creates a student with the specified id and name. Student(int id, const string& name) { } // Returns the student name. string get_name() const { } // Returns the student id. int get_id () const { } // Sets the student...
Given a class called Student and a class called Course that contains an ArrayList of Student. Write a method called getDeansList() as described below. Refer to Student.java below to learn what methods are available. I will paste both of the simple .JAVA codes below COURSE.JAVA import java.util.*; import java.io.*; /****************************************************** * A list of students in a course *****************************************************/ public class Course{ /** collection of Students */ private ArrayList<Student> roster; /***************************************************** Constructor for objects of class Course *****************************************************/...
