1 Hello World
世界，你好。
This is the source code of the traditional Hello World program.
這是傳統的Hello World的原始碼。

// This is a comment, and will be ignored by the compiler
// 本行為註釋，會被編譯器忽略
// You can test this code by clicking the "Run" button over there ->
// 點選Run按鈕即可執行此程式碼

 shortcut
// 或者希望使用鍵盤，可以用"Ctrl + Enter"快捷鍵
// This code is editable, feel free to hack it!
// 點選此程式碼即可編輯
// You can always return to the original code by clicking the "Reset" button ->
// 隨時點選"Reset"按鈕回到初始程式碼
// This is the main function
// 這是主函式
fn main() {
    // The statements here will be executed when the compiled binary is
 
 called

    // Print text to the console
    println!("Hello World!");
}

println! is a macro that prints text to the console.
println! 是一個向控制檯列印文字的巨集
A binary can be generated using the Rust compiler: rustc.
使用Rust編譯器命令rustc即可生成二進位制檔案
$ rustc hello.rs
rustc will produce a hello binary that can be executed.

rustc 將產生一個可執行的二進位制檔案hello
$ ./hello
Hello World!
