用各种编程语言打出”Hello, World!”

下面是用多种编程语言打印 “Hello, World!” 的代码示例：

1. Python

print("Hello, World!")

2. JavaScript

console.log("Hello, World!");

3. Java

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

4. C

#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}

5. C++

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

6. Ruby

puts "Hello, World!"

7. PHP

<?php
echo "Hello, World!";
?>

8. Swift

import Swift

print("Hello, World!")

9. Go (Golang)

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}

10. R

cat("Hello, World!\n")

11. Kotlin

fun main() {
    println("Hello, World!")
}

12. Perl

print "Hello, World!\n";

13. Lua

print("Hello, World!")

14. TypeScript

console.log("Hello, World!");

15. Shell (Bash)

echo "Hello, World!"

16. MATLAB

disp('Hello, World!')

17. Assembly (x86)

section .data
    msg db 'Hello, World!', 0

section .text
    global _start

_start:
    ; write the message to stdout
    mov eax, 4          ; syscall number for sys_write
    mov ebx, 1          ; file descriptor 1 (stdout)
    mov ecx, msg        ; message to print
    mov edx, 13         ; length of the message
    int 0x80            ; make the syscall

    ; exit the program
    mov eax, 1          ; syscall number for sys_exit
    xor ebx, ebx        ; exit code 0
    int 0x80            ; make the syscall

18. Haskell

main :: IO ()
main = putStrLn "Hello, World!"

19. Rust

fn main() {
    println!("Hello, World!");
}

20. V (Vlang)

fn main() {
    println('Hello, World!')
}

这些示例展示了用不同编程语言打印 “Hello, World!” 的基本方法。
