To write a program in C++ to prepare a student Record using class and object.

To write a program in C++ to prepare a student Record using class and object.

Algorithm to solve the above problem:

1. Start

2. Create a class record.

3. Read the name, Rollno ,mark1, mark2, mark3 of the student.

4. Calculate the average of mark as Avg = (mark1 + mark2 + mark3) / 3

5. Display the student record.

6. Stop.

Implementation of the above problem in C++:

#include<iostream>

using namespace std;

class record

{

public:

char name[20];

int rollno;

int m1,m2,m3;

float avg;

void getdata()

{

cout<<"\n Enter the name: " ;

cin>>name;

cout<<"Enter the rollno: ";

cin>>rollno;

cout<<"enter the m1,m2,m3: \n";

cin>>m1>>m2>>m3;

}

void calculate()

{

avg=(m1+m2+m3)/3;

}

void display()

{

cout<<"\nName: "<<name;

cout<<"\nRollno: "<<rollno;

cout<<"\nMark1: "<<m1;

cout<<"\nMark2: "<<m2;

cout<<"\nMark3: "<<m3;

cout<<"\nAvg: "<<avg;

}

};

void main()

{

record r;

r.getdata();

r.calculate();

r.display();

return 0;

}

The output of the above program is tested on www.jdoodle.com

Output:

Enter the name: Mukesh

Enter the rollno: 101

enter the m1,m2,m3: 34 65 78

Name: Mukesh

Rollno: 101

Mark1: 34

Mark2: 65

Mark3: 78

Avg: 59

Thanks
