[JavaScript知识库]A+B problem(各种代码大合集)

来就来个齐全的··

为了防止题目变量值过大

所以拒绝int，选择long long(C或C++)

···················································重点···················································

C语言代码

#include <stdio.h>
int main()
{
    long long a,b;
    scanf("%d%d",&a,&b);
    printf("%d\n", a+b);
    return 0;
}

C++代码

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

Pascal代码

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

Python?2?代码

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

Python?3?代码

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

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);
        int a = cin.nextInt(), b = cin.nextInt();
        System.out.println(a+b);
    }
}

JavaScript （Node.js）代码

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()

Ruby 代码

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

PHP

<?php
$input = trim(file_get_contents("php://stdin"));
list($a, $b) = explode(' ', $input);
echo $a + $b;

Rust

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

package main
import "fmt"
func main() {
    var a, b int
    fmt.Scanf("%d%d", &a, &b)
    fmt.Println(a+b)
}

C# Mono

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

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

fun main(args: Array<String>) {
    val (a, b) = readLine()!!.split(' ').map(String::toInt)
    println(a + b)
}
Haskell
main = do
    [a, b] <- (map read . words) `fmap` getLine
    print (a+b)

Scala

object Main extends App {
    println(scala.io.StdIn.readLine().split(" ").map(_.toInt).sum)
}

Perl

my $in = <STDIN>;
chomp $in;
$in = [split /[\s,]+/, $in];
my $c = $in->[0] + $in->[1];
print "$c\n";

文言

施「require('fs').readFileSync」於「「/dev/stdin」」。名之曰「數據」。
施「(buf => buf.toString().trim())」於「數據」。昔之「數據」者。今其是矣。
施「(s => s.split(' '))」於「數據」。昔之「數據」者。今其是矣。
注曰。「「文言尚菜，無對象之操作，故需 JavaScript 之语法」」。
夫「數據」之一。取一以施「parseInt」。名之曰「甲」。
夫「數據」之二。取一以施「parseInt」。名之曰「乙」。
加「甲」以「乙」。書之。
