ADDITION OF TWO NUMBER BY USING CLASS AND FUNCTION

-

hello friends....

TAKE THE FIRST STEP TO KNOWLEDGE FRIENDS BECAUSE KNOWLEDGE IS FREE.

/* WRITE A PROGRAM ADDITION OF TWO NUMBER BY USING CLASS AND FUNCTION IN C++ */

#include<iostream.h>
#include<conio.h>
class addition
{
   int a,b,c;
   public:
      void getdata()                   //emplicit declaration finction
      {
            cout<<"enter first value :";
            cin>>a;
            cout<<"enter second value :";
            cin>>b;
      }
      void calculate()
      {
c = a+b;
      }
      void putdata();
};

void addition::putdata()         //explicit declaration function
{
   cout<<"a="<<a<<endl<<"b="<<b<<endl;
   cout<<"final ans is : "<<c<<endl;
}

void main()
{
   addition d;
   clrscr();
   d.getdata();
   d.calculate();
   d.putdata();
   getch();
}

     OUTPUT
=================

enter first value :10
enter second value :20
a=10
b=20
final ans is : 30
