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

Q: Where are the input and the output?

A: Your program shall always read input from stdin (Standard Input) and write output to stdout (Standard Output). For example, you can use 'scanf' in C or 'cin' in C++ to read from stdin, and use 'printf' in C or 'cout' in C++ to write to stdout.

You shall not output any extra data to standard output other than that required by the problem, otherwise you will get a "Wrong Answer".

User programs are not allowed to open and read from/write to files. You will get a "Runtime Error" or a "Wrong Answer"if you try to do so.

Here is a sample solution to problem 1000 using C++/G++:
#include <iostream>

using namespace std;

int main()
{
int a,b;
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 to problem 1000 using C/GCC:
#include <stdio.h>

int main()
{
int a,b;
scanf("%d %d",&a, &b);
printf("%d\n",a+b);
return 0;
}
Here is a sample solution to problem 1000 using Pascal:
program p1000(Input,Output);

var
a,b:Integer;
begin
Readln(a,b);
Writeln(a+b);
end.
Here is a sample solution to problem 1000 using Java:

Now java compiler is jdk 1.5, next is program for 1000
import java.io.*;
import java.util.*;
public class Main
{
public static void main(String args[]) throws Exception
{
Scanner cin=new Scanner(System.in);
int a=cin.nextInt(),b=cin.nextInt();
System.out.println(a+b);
}
}
Old program for jdk 1.4
import java.io.*;
import java.util.*;

public class Main
{
public static void main (String args[]) throws Exception
{
BufferedReader stdin =
new BufferedReader(
new InputStreamReader(System.in));

String line = stdin.readLine();
StringTokenizer st = new StringTokenizer(line);
int a = Integer.parseInt(st.nextToken());
int b = Integer.parseInt(st.nextToken());
System.out.println(a+b);
}
}
Here is a sample solution to problem 1000 using Fortran:
	PROGRAM P1000
IMPLICIT NONE
INTEGER :: A, B
READ(*,*) A, B
WRITE(*, "(I0)") A + B
END PROGRAM P1000
