The document describes a C++ program that adds two numbers. The program prompts the user to enter values for variables a and b, stores their sum in a variable sum, and prints the sum. When run with sample inputs of 2 for a and 3 for b, the program correctly outputs the sum of 5.

1. Practical No.-3
Aim
: To demonstrate the program for adding
two number.
Source code :
#include<iostream.h>
#include<conio.h>
void main()
{
int a, b,sum;
cout <<”Enter the value of a ”;
cin>>a;
cout<<”Enter the value of b”;
cin>>b;
sum=a+b;
cout<<”sum”<<sum;
}
Output
:
Enter the value of a = 2
Enter the value of b =3
sum = 5
