int main ()
{
  int a, b;
  scanf("%d %d",&a,&b);
  printf("%d",a+b);
  return 0;
}

C++ :

#include<iostream>
using namespace std;
int main()
{
	int a,b;
    cin>>a>>b;
    a+=b;
	cout<<a;
	return 0;
}

Pascal :

var a,b:integer;begin read(a,b);write(a+b);end.

Java :

import java.util.*;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		int a = 0;
		int b = 0;
		Scanner in = new Scanner(System.in);
		a = in.nextInt();
		b = in.nextInt();
		System.out.println(a+b);
	}

}

Python :

# coding=utf-8
print(sum(map(int, input(). split())))
