Addition

Read two integers $a$ and $b$, then print $a+b$.

Input and output in C

#include <stdio.h>
...
scanf("%d%d", &a, &b);
printf("%d\n", a + b);

Input and output in C++

#include <iostream>
...
cin >> a >> b;
cout << a + b << endl;

Input and output in Java

import java.util.Scanner;
...
Scanner sc = new Scanner(System.in);
a = sc.nextInt();
b = sc.nextInt();
System.out.println(a + b);

The first line contains $a$ and $b$, separated by one space. Both values are integers between -100,000 and 100,000.

Print $a+b$ on the first line.
