Implement StudentRecord class Private member variables: int CWID, double grade I

Question

Implement StudentRecord class

Private member variables: int CWID, double grade

Implement appropriate constructors and accessor/mutator functions

Overload +, == for StudentRecord class

== compares CWID

+ adds up grades for students

Creates new StudentRecord object

New CWID = old CWID1 + old CWID2

Overload either as member or non-member functions

Now, overload the << and >> operators In your main() function, you can now do

Sample input:

Sample output:

code here

#include <iostream>
using namespace std;

class StudentRecord {
public:
   StudentRecord() : CWID(0), grade(0) {
   }
   StudentRecord(int c, double g) : CWID(c), grade(g) {
   }
  
   int getCWID() const {return CWID;}
   double getGrade() const {return grade;}
   void setCWID(int c) {
   CWID = c;
   }
   void setGrade(double g) {
   grade = g;
   }

   const StudentRecord operator +(const StudentRecord& other);
   bool operator ==(const StudentRecord& other);
  
   //declare and overload >> and << oerators
private:
   int CWID;
   double grade;
};

const StudentRecord StudentRecord::operator +(const StudentRecord& other) {
   return StudentRecord(CWID + other.getCWID(), grade + other.getGrade());
}

bool StudentRecord::operator ==(const StudentRecord& other) {
   if (CWID == other.getCWID()) {
       return true;
   }
   return false;
}

//define and overload >> and << oerators

int main() {
   StudentRecord eric, nick;
   cin >> eric >> nick;
   cout << eric << nick;

   StudentRecord enik = eric + nick;
   cout << enik;
}

Explanation / Answer

#include <iostream>
using namespace std;

class StudentRecord {
    public:
        StudentRecord() : CWID(0), grade(0) {
        }
        StudentRecord(int c, double g) : CWID(c), grade(g) {
        }
  
        int getCWID() const {return CWID;}
        double getGrade() const {return grade;}
      
        void setCWID(int c) {
           CWID = c;
        }
        void setGrade(double g) {
           grade = g;
        }

        const StudentRecord operator +(const StudentRecord& other);
        bool operator ==(const StudentRecord& other);
  
        friend ostream & operator << (ostream &out, const StudentRecord &c);
        friend istream & operator >> (istream &in, StudentRecord &c);
    private:
        int CWID;
        double grade;
};

const StudentRecord StudentRecord::operator +(const StudentRecord& other) {
    return StudentRecord(CWID + other.getCWID(), grade + other.getGrade());
}

bool StudentRecord::operator ==(const StudentRecord& other) {
    if (CWID == other.getCWID()) {
        return true;
    }
    return false;
}
ostream & operator << (ostream &out, const StudentRecord &c)
{
    out <<"CWID : "<<c.CWID<<" , Grade : "<<c.grade<<endl;
    return out;
}

istream & operator >> (istream &in, StudentRecord &c)
{
    cout << "Enter CWID: ";
    in >> c.CWID;
    cout << "Enter Grade : ";
    in >> c.grade;
    return in;
}
int main() {
    StudentRecord eric, nick;
    cin >> eric >> nick;
    cout << eric << nick;

    StudentRecord enik = eric + nick;
    cout << enik;
}
