Question

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)

setGPA (float passed to function to set GPA)

setClasses (integer passed to function to set Number of enrolled classes)

DisplayStudent (display member fields’ values from within this function)

SetALL (strings, float and integer passed to function setting the appropriate field)

Application will:

Create four class members (student1, student2, student3, student4)

Initialize the class members with the SetALL function

Display each member’s individual characteristics

Allow user to enter a NEW class member, student5 or student6)

Allow user to run this repeatedly (some sort of menu presentation??)

Output Example - Displaying the students' data:

Student ID: AF101

Smith, Zachery H.

4 Classes Taken This Semester

Current GPA is 3.2

Student ID: HJ389

Jones, Alias T.

2 Classes Taken This Semester

Current GPA is 3.3

Student ID: KL209

Luzer, Emma P.

4 Classes Taken This Semester

Current GPA is 4

Student ID: LL309

Beans, Hill O.

3 Classes Taken This Semester

Current GPA is 2.5

c++ code:

#include <iostream>

using namespace std;

//student class
class Student
{
//member variables
string ID;
string LastName;
string FirstName;
float GPA;
int classes;

//functions
public:
//setters
void setID (string id){
this->ID =id;
}
void setLastName (string lname)
{
this->LastName=lname;
}
void setFirstName (string fname)
{
this->FirstName=fname;
}
void setGPA (float gpa)
{
this->GPA=gpa;
}
void setClasses (int classes)
{
this->classes=classes;
}
  
//function to display
void DisplayStudent()
{
cout<<"\nStudent ID: "<<this->ID<<
"\n"<<this->FirstName<<", "<<this->LastName<<".\n"
<<this->classes<<" Classes Taken This Semester"
<<"\nCurrent GPA is "<<this->GPA<<"\n\n";
}
//function to set all variables
void SetALL (string id,string lname,string fname, float gpa,int cls)
{
this->ID =id;
this->LastName=lname;
this->FirstName=fname;
this->GPA=gpa;
this->classes=cls;

}
};

int main()
{
Student s[6]; //array of objects
int n=4,cls;
string id,lname,fname;
float gpa;
char c;

//set all values
s[0].SetALL("AF101", "Zachery H" ,"Smith",3.2,4 );
s[1].SetALL("HJ389", "Alias T", "Jones",2,3.3);
s[2].SetALL("KL209","Emma P","Luzer",4,4);
s[3].SetALL("LL309"," Hill O","Beans",3,2.5);

//display
for(int i=0;i<n;i++)
s[i].DisplayStudent();

//get hit to continue
cout << "\nHit Any Key to continue...";
cin.get();
  
//get values from user
do
{
cout<<"\nEnter ID: ";
cin>>id;
cout<<"\nEnter LastName: ";
cin>>lname;
cout<<"\nEnter FirstName: ";
cin>>fname;
cout<<"\nEnter GPA: ";
cin>>gpa;
cout<<"\nEnter number of classes: ";
cin>>cls;
s[n].SetALL(id,lname,fname,gpa,cls); //add to class

cout<<"\nDo you want to continue (y/n):";
cin>>c;
}while(c=='y' && n<5);
return 0;
}

output:
