Create a C++ class for a student with member function accepting marks and display all information using of manipulators

Assignment 17

 Create a C++ class for a student object with the following attributes—roll no, name, number of subjects, marks of subjects. Write member function for accepting marks and display all information of student along with total and Percentage. Display mark list with using of manipulators.

Program Code for run:

#include <iostream>

using namespace std;

#include<iomanip>

class Student

{

            private:

                        int Roll_Number, Marks[5];

                        char Stud_Name[80], Class;

                        float Per;

            public:

                        void accept();

                        void display();

};

void Student :: accept()

{

            cout << " Accept Student Roll Number "<< endl;

            cin >> Roll_Number;

            cout << " Accept Student Name"<< endl;

            cin >> Stud_Name;

            cout << " Accept Student Marks "<< endl;

            float total = 0;

            for( int i = 0; i < 5; i++)

            {

                        cout << " \t Subject "<< i + 1 << endl;

                        cin >> Marks[i];

                        total = total + Marks[i];

            }

            Per = total / 5; // calculate Percentage

            if(Per < 60)

                        Class='B';

            if((Per >= 60)&&(Per < 70))

                        Class='A';

            if(Per >= 70)

                        Class='O';

}

void Student :: display()

{

               cout << setw(7) << Roll_Number << setw(7) << Stud_Name << setw(7);

               for( int i = 0; i < 5; i++)

                        cout<< Marks[i] << setw(7);

               cout << setw(7) << setprecision(2) << Per << "    " << Class << "\n";

}

 

int main()

{

            int n, i;

            Student p[20];

            cout << " * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * " << endl;

            cout << " \t How many Student data to enter " << endl;

            cout << " * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * " << endl;

            cin >> n;

            cout << " * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * " << endl;

            cout << " \t Enter Student Details " << endl;

            for ( i = 0 ; i < n ; i ++)

            {

                cout<<"* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * " << endl;

                cout<<"\t Enter Student Details of Student := " << i + 1 << endl;

                cout<<"* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * " << endl;

                p[i].accept();

            }

            cout << " * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * " << endl;

            cout << " Display Student Details " << endl;

            cout << " * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * " << endl;

            cout << setw(7) << "RNO" << setw(7) << "SName" << setw(7) << "Sub1";

            cout << setw(7) << "Sub 2"<< setw(7) << "Sub 3" << setw(7) << "Sub4";

          cout<< setw(7) << "Sub 5" << setw(7) << "Per" << setw(7) << "Class" <<endl;

            cout << " * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * " << endl;

            for ( i = 0 ; i < n ; i ++)

                        p[i].display();

            cout << " * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * " << endl;

            return 0;

}

Output of Program:
