Write a program to test your class.

Define a class named Student, create following members in it: Data Members: student_name, rollno, class (BCA/MCA), semester, sub1_marks,sub2_marks, sub3_marks,  total marks, average, percentage.                                   
          Member Functions: 
To enter the information of a student. 
To calculate his/her total, average, percentage.
To display the result.  

Write a program to test your class.


Coding:

#include<iostream.h>

#include<stdio.h>

#include<conio.h>

class student

{

  int roll,total_marks,sub1_marks,sub2_marks,sub3_marks;

  char stu_name[20],clss[3],sem[10];

  float avg,percentage;

  public:

     void getdata();

     void calculation();

     void display();

};

void student::getdata()

{

  cout<<"\nEnter Student Name:"<<" ";

  gets(stu_name);

  cout<<"\nEnter Student Roll No.:"<<" ";

  cin>>roll;

  cout<<"\nEnter class:"<<" ";

  gets(clss);

  cout<<"\nEnter semester:"<<" ";

  gets(sem);

  cout<<"\nEnter subject marks:"<<" ";

  cin>>sub1_marks>>sub2_marks>>sub3_marks;

}

void student::calculation()

{

  total_marks=sub1_marks+sub2_marks+sub3_marks;

  avg=total_marks/3;

  percentage=total_marks*100/300;

}

void student::display()

{

  cout<<"\nThe Result is:\n";

  cout<<"\nTotal Marks="<<total_marks;

  cout<<"\nAverage Marks="<<avg;

  cout<<"\nPercentage Marks="<<percentage;

}

void main()

{

 clrscr();

 student stu;

 stu.getdata();

 stu.calculation();

 stu.display();

 getch();

}

Output:
