// 原始字符串
let originalString = "Hello, world!";

// 添加单词
let newString = originalString + " Welcome to the programming.";

console.log(newString);

public class Main {
    public static void main(String[] args) {
        // 原始字符串
        String originalString = "Hello, world!";

        // 添加单词
        String newString = originalString + " Welcome to the programming.";

        System.out.println(newString);
    }
}

using System;

class Program {
    static void Main() {
        // 原始字符串
        string originalString = "Hello, world!";

        // 添加单词
        string newString = originalString + " Welcome to the programming.";

        Console.WriteLine(newString);
    }
}

# 原始字符串
original_string = "Hello, world!"

# 添加单词
new_string = original_string + " Welcome to the programming."

puts new_string

<?php
