#include<iostream.h>
#include<conio.h>
class add
{
public:
int a;
int b;
int c;
public:
void addition(void);
};
void  add::addition(void)
{
cout<<endl<<"please enter the value of a and b:";
cin>>a>>b;
cout<<endl<<”a=”<<a;
cout<<endl<<”b=”<<b;
c=a+b;
cout<<endl<<"the sum of those numbers:-"<<c;
}
void main()
{
clrscr();
add A;
A.addition();
getch();
}

The output of the program is given below. 


In this program,


I am using class to add two number, we can also add two number without using class.my class_name is “add”.

class add {}

We using three variable a, b, c and its publically defined in class datamember. where a, b is a number that you enter to add and c include result of this two number.

Public:
int a;
int b;
int c;


In the class member function we create a function that include all instruction to add two number. my function name is “addition” and it is a void function and its arguments also void.

public:
void addition(void);

We call the function outside of the class by using scope resolution operator ::

 void  add::addition(void) {}

cout, The cout object in C++ is an object of class iostream. It is used to display the output to the standard output device i.e. monitor.


cin, The cin object in C++ is an object of class iostream. It is used to accept the input from the standard input device i.e. keyboard.

In this function you can see the use of cout and cin:-


void  add::addition(void)
{
cout<<endl<<"plese enter the value of a and b:";
cin>>a>>b;
cout<<endl<<a;
cout<<endl<<b;
c=a+b;
cout<<endl<<"the sum of those numbers:"<<c;
}

 And we using main function to call the class by using object of that class:-


void main()
{
clrscr();
add A;               //object created
A.addition();      //call the function by using object 
getch();
}
 


Output of the program:-

please enter the value of a and b: 12 13
a=12
b=13
the sum of those numbers:-25
