不同编程语言的a+b=c表示方法

C 语言
#include <stdio.h>
int main()
{
int a, b;
while(scanf("%d%d", &a, &b) != EOF)
printf("%d\n", a + b);
}

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

C# 语言
using System;
class Program {
public static void Main() {
string line;
string []p;
int a,b;
while((line=Console.ReadLine())!=null){
p=line.Split(' ');
a=int.Parse(p[0]);b=int.Parse(p[1]);
Console.WriteLine(a+b);
}
}
}

Java 语言
//package main
//注意不要添加包名称，否则会报错。

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

Ruby 语言
a=gets
while a != nil && a != "" && a != "\r" && a != "\n" do
arr = a.split(" ")
sum = 0
arr.each_with_index do |value, index|
sum = sum + value.to_i
end
puts sum.to_s
a=gets
end

Bash 语言
#!/bin/bash

read -a arr
#echo ${#arr[@]}
while [ ${#arr[@]} -eq 2 ]
do
sum=$((${arr[0]}+${arr[1]}))
echo "$sum"
read -a arr
done

Obj-C 语言
#import <Foundation/Foundation.h>
int primeNumber(long int m)
{
int i;
for (i=2; i*i<=m; i++) {
if (m%i==0)
return 0;
}
return 1;
}
int main(int argc,char * argv[])
{
NSAutoreleasePool *pool=[[NSAutoreleasePool alloc] init];
int n,flag;
long int m;
int a,b;
while(scanf("%d %d",&a, &b) != EOF)
printf("%d\n",a+b);
return 0;
[pool drain];
return 0;
}

NodeJS 语言
process.stdin.resume();
process.stdin.setEncoding('utf-8');

var input = "";
var input_array = "";

//这里不灵活，需要全部读取数据后再处理，容易超内存。
process.stdin.on('data', function (data) {
input += data;
});

var solveMeFirst = (a, b) => a+b;

process.stdin.on('end', function () {
let arr = input.split("\n");
for (var i=0; i<arr.length; i++) {
if (arr[i] != '') {
input_array = arr[i].split(" ");

let inline = 0;
let res;
let _a = parseInt(input_array[inline].trim(), 10);
inline += 1;

let _b = parseInt(input_array[inline].trim(), 10);
inline += 1;

res = solveMeFirst(_a, _b);
process.stdout.write("" + res + "\n");
}
}
});

PHP 语言
<?php
function solveMeFirst($a,$b){
return $a + $b;
}
$handle = fopen ("php://stdin","r");
$s = fgets($handle);
while ($s != "") {
$a = explode(" ", $s);
$sum = solveMeFirst((int)$a[0],(int)$a[1]);
print ($sum);
print ("\n");
$s = fgets($handle);
}
fclose($handle);
?>

Python语言
Python2:

#!/usr/bin/env python
# coding=utf-8
# Python使用的是2.7.6，缩进可以使用tab、4个空格或2个空格，但是只能任选其中一种，不能多种混用
while 1:
a=[]
s = raw_input()
# raw_input()里面不要有任何提示信息
if s != "":
for x in s.split():
a.append(int(x))

print sum(a)
else:
break

Python3:

#!/usr/bin/env python
# coding=utf-8
# Python使用的是3.4.3，缩进可以使用tab、4个空格或2个空格，但是只能任选其中一种，不能多种混用
while 1:
a=[]
s = input()

if s != "":
for x in s.split():
a.append(int(x))

print(sum(a))
else:
break

Go 语言
package main
import "fmt"
import "io"
func main() {
a:=0
b:=0
for {
_, err := fmt.Scanf("%d%d",&a,&b)
if err == io.EOF {
break
} else {
fmt.Printf("%d\n",a+b)
}
}
}

JavaScript 语言
while(line=readline()){
var lines = line.split(' ');
var a = parseInt(lines[0]);
var b = parseInt(lines[1]);
print(a+b);
}
