Question

Define a class in C++ that has the following properties:

class student{

string name, id;

float gpa; // 0 <= gpa <= 4

public:

student(); //cons_0 ==> set default values with empty string and 0.00 as

gpa

student(string, string, float); //cons_1

student(const student&); //cost_2

string get_name();

string get_id();

float get_gpa();

void set_name(string);

void set_id(string);

void set_gpa(float);

}

In your main function (should be declared in a file named

'program_01_yourUNTID.cpp')

you will create:

i) three objects of type: student (say, a, b, c).

ii) initialize 'a' with constructor cons_0,

initialize 'c' with constructor cons_1,

initialize 'b' with constructor cons_2, you can pass either a or

c

iii) print all the properties of each object

iv) create an array of 5 objects. You can ask the user either

a) to insert the properties while constructing the

new object

b) to use a predefined object (say, b) to construct

the new object

(we will prefer a menu to handle such scenario)

v) print the name and id of the student with highest gpa out of the 5

students;

Explanation / Answer

#include<iostream>
using namespace std;
class student{
string name, id;
float gpa; // 0 <= gpa <= 4
public:
student()//cons_0 ==> set default values with empty string and 0.00 as
{
name="";
id = "";
gpa = 0;
}
student(string n, string i, float gp)
{
name =n;
id=i;
gpa =gp;
} //cons_1
student(const student&)//cost_2
{
name = *student.name;
id = *student.id;
gpa = *student.gpa;
}
string get_name()
{
return name;
}
string get_id()
{
return id;
}
float get_gpa()
{
return gpa;
}
void set_name(string n)
{
name =n;
}
void set_id(string i)
{
id =i;
}
void set_gpa(float g)
{
gpa=g;
}
void display()
{
cout<<"name is:"<<name;
cout<<"id is:"<<id;
cout<<"gpa is:"<<gpa;
}
};

int main()
{
student a = new student();
student b = a;
student c = new student("ankit","1","9");
a.display();
b.display();
c.display();
student arr[5];
arr[0]= new student("a","1",1);
arr[1]= new student("b","2",2);
arr[2]= new student("c","3",3);
arr[3]= new student("d","4",4);
arr[4]= new student("e","5",5);
int max=-1;
int maxind=0;
for(int i=0;i<5;i++)
{
if(arr[i].get_gpa()>max)
{
max = arr[i].get_gpa();
maxind =i;
}

}
cout<<"highest gpa student details are as follows:"<<endl;
arr[maxind].display();
}
