C :

#include <stdio.h>

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

C++ :

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

Pascal :

program p1000(Input,Output); 
var 
  a,b:Integer; 
begin 
   Readln(a,b); 
   Writeln(a+b); 
end.

Java :

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);
            }
}

Python :

a = input()
a = a.split()
b = []
for i in a:
        b.append(int(i))
print (sum(b))
