Class Programming

Write a program to accept the student detail such as name and 3 different marks by get_data() method and display the name and average of marks using display() method. Define a friend class for calculating the average of marks using the method marrk_avg().

Implementation of the above problem:

#include<iostream.h>

#include<conio.h>

class student

{

char name[20];

int mark1,mark2,mark3;

friend class friendclass;

public:

void get_data()

{

cout<<"\nEnter name:";

cin>>name;

cout<<"\nEnter 3 marks:";

cin>>mark1>>mark2>>mark3;

}

void display(int a)

{

cout<<"\nOutput\n ";

cout<<"=============\n";

cout<<"\nName ="<<name;

cout<<"\nAverage ="<<a;

}

};

class friendclass

{

public:

void mark_avg(student &stud)

{

int avg=(stud.mark1+stud.mark2+stud.mark3)/3;

stud.display(avg);

}

};

void main()

{

clrscr();

student s;

s.get_data();

friendclass obj;

obj.mark_avg(s);

getch();

}
