C++ 代码

#include <iostream>

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

C 代码

#include <stdio.h>

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

Java 代码

import java.io.*;
import java.util.*;
public class Main {
public static void main(String args[]) throws Exception {
Scanner cin=new Scanner(System.in);
var a = cin.nextInt();
var b = cin.nextInt();
System.out.println(a + b);
}
}

Python 代码

import sys
for line in sys.stdin:
print sum(map(int, line.split()))

Python3 代码

import sys
for line in sys.stdin:
print(sum(map(int, line.split())))

Javascript 代码

var fs = require('fs');
var buf = '';
process.stdin.on('readable', function() {
var chunk = process.stdin.read();
if (chunk) buf += chunk.toString();
});
process.stdin.on('end', function() {
buf.split('\n').forEach(function(line) {
var tokens = line.split(' ').map(function(x) { return parseInt(x); });
if (tokens.length != 2) return;
console.log(tokens.reduce(function(a, b) { return a + b; }));
});
});

请使用C++11(Clang)

#include <iostream>
using namespace std;

int main() {
    int 甲, 乙;
    cin >> 甲 >> 乙;
    cout << 甲 + 乙;

    return 0;
}

最关键还AC了

#include <stdio.h>

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

C++

#include <iostream>
#include <cstdio>

using namespace std;

int main()
{
    int a,b;
    cin >> a >> b;
    cout << a+b << endl;
    return 0;
}

Pascal

var a, b: longint;
begin
    readln(a,b);
    writeln(a+b);
end.

Python2

s = raw_input().split()
print int(s[0]) + int(s[1])

Python3

s = input().split()
print(int(s[0]) + int(s[1]))

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();

JavaScript （Node.js）

const fs = require('fs')
const data = fs.readFileSync('/dev/stdin')
const result = data.toString('ascii').trim().split(' ').map(x => parseInt(x)).reduce((a, b) => a + b, 0)
console.log(result)
process.exit() // 请注意必须在出口点处加入此行

Ruby

a, b = gets.split.map(&:to_i)
print a+b
PHP

<?php ```cpp $input = trim(file_get_contents("php://stdin")); list($a, $b) = explode(' ', $input); echo $a + $b; ``` Rust ```cpp use std::io; fn main(){ let mut input=String::new(); io::stdin().read_line(&mut input).unwrap(); let mut s=input.trim().split(' '); let a:i32=s.next().unwrap() .parse().unwrap(); let b:i32=s.next().unwrap() .parse().unwrap(); println!("{}",a+b); } ``` Go ```cpp package main import "fmt" func main() { var a, b int fmt.Scanf("%d%d", &a, &b) fmt.Println(a+b) } ``` C# Mono ```cpp using System; public class APlusB{ private static void Main(){ string[] input = Console.ReadLine().Split(' '); Console.WriteLine(int.Parse(input[0]) + int.Parse(input[1])); } } ``` Visual Basic Mono ```cpp Imports System Module APlusB Sub Main() Dim ins As String() = Console.ReadLine().Split(New Char(){" "c}) Console.WriteLine(Int(ins(0))+Int(ins(1))) End Sub End Module ``` Kotlin ```cpp fun main(args: Array) { val (a, b) = readLine()!!.split(' ').map(String::toInt) println(a + b) } ``` Haskell ```cpp main = do [a, b] <- (map read . words) `fmap` getLine print (a+b) ``` Scala ```cpp object Main extends App { println(scala.io.StdIn.readLine().split(" ").map(_.toInt).sum) } ``` Perl ```cpp my $in = ; chomp $in; $in = [split /[\s,]+/, $in]; my $c = $in->[0] + $in->[1]; print "$c\n"; ```

感觉还是c++** or **c语言最容易看懂，其他要么是没有加号要么就是一大堆看不懂
