Description

Calculate a+b

Input

Two integer a,b (0<=a,b<=10)

Output

Output a+b

Sample Input

1 2

Sample Output

3

HINT

Here is a sample solution using C++/G++: 
#include "iostream"

using namespace std;

int  main()

{

    int a,b;

    while( cin >> a >> b )

        cout << a+b << endl;

    return 0;

}


It's important that the return type of main() must be int when you use G++/GCC,or you may get compile error.


Here is a sample solution using C/GCC:
#include 

int main()

{

    int a,b;

    while( scanf("%d %d",&a, &b) != EOF )

         printf("%d\n",a+b);

}
 
Here is a sample solution using PASCAL:

program p1501(Input,Output); 

var 

  a,b:Integer; 

begin 

   Readln(a,b); 

   Writeln(a+b); 

end.
 
Here is a sample solution using Java:

import java.io.*;

import java.util.*;

public class Main {

    public static void main(String args[]) throws Exception {

        Scanner cin = new Scanner(System.in);

        while (cin.hasNext()) {

            int a = cin.nextInt(), b = cin.nextInt();

            System.out.println(a + b);

        }

    }

}
