Problem Statement:

XYZ institute has collected data regarding covid-19 vaccinated students of age group 18-24yrs . On the basis of provided data a programmer can manage information in a way that it will be available to the Administration ONLY. Students’ details will include, Student Name, Vaccine Name, Student Age, and Number of doses taken.

 

Create a class Student as per the programming constructs given in class diagram below.

 

Student

-std_id[20]:char -vac_name[10]:char - age:int - num_dose:int

+ setName(const char[]) + setVaccine(const char[]) + setAge(int) + setDose(int) + getName() + getVaccine(); + getAge(); + getDose();

 

Friend function of Student Class

display (Student std)

Task to be performed:

Ø  Create class objects std1, std2 and std3 of class Student.

Ø  Use default constructor to assign default data values to the class object std1.

Ø  Use parameterized constructor to assign data values to the class object std2.

Ø  Use Setter() and Getter() methods to assign and print values of the class object std3.

Ø  Use Friend function display() for objects std1 and std2 only.

Ø  You will print data values of object std3 using getName(), getVaccine(), getAge(), getDose() and getter() member functions.

Note:

Ø  You will ONLY use given data values in Table1 for the class Student objects std1, std2 and std3 respectively.

 

Student ID	Vaccine Name	Student Age	Number of doses
Enter your own VU studentID here	Sinovac	20	1
BC123456789	Sinopharm	21	2
MC123456789	Moderna	22	3

}

return std_id;

}

string Student::getVaccine(){

return vac_name;

}

int Student::getAge(){

return age;

}

int Student::getDose(){

return num_dose;

}

int main(){

Student std1, std2("BC123456789", " Sinopharm", 21,2), std3;

std3.setName("MC123456789");

std3.setVaccine("Moderna");

std3.setAge(22);

std3.setDose(3);

cout<<"Printing std1 object values using display().........."<<endl;

display(std1);

cout<<"\nPrinting std2 object values using display().........."<<endl;

display(std2);

cout<<"\nPrinting std3 object values using getter method.........."<<endl;

cout<<"Student Id : "<<std3.getName()<<endl;

cout<<"Age : "<<std3.getAge()<<endl;

cout<<"Vaccination : "<<std3.getVaccine()<<endl;

cout<<"Vaccination Dose : "<<std3.getDose()<<endl;

return 0;
