Ruby程序打印Hello World！

打印Hello World！ 在Ruby中 (Printing Hello World! In Ruby)

To print text (Hello World! Or anything else), we use following two methods,

要打印文本(Hello World！或其他)，我们使用以下两种方法，

1. puts : The word "puts" stands for put string. It adds a newline after the string.

   puts ：“ puts”一词代表放置字符串。 它在字符串后添加换行符。

2. print : The functionality of this method is same as of puts but it does not adds newlines implicitly like puts.

   print ：此方法的功能与puts相同，但不会像puts那样隐式添加换行符。

Variables used: No variables are required as we only have to print the statements. We don't have to store anything.

使用的变量：不需要变量，因为我们只需要打印语句。 我们不必存储任何东西。

Code explanation:

代码说明：

The code illustrates an example to print a string "Hello World!" in Ruby programming language. This uses the puts and print methods to print the string and output "Hello world" using these methods.

该代码说明了打印字符串“ Hello World！”的示例。 用Ruby编程语言编写 。 这使用puts和print方法来打印字符串，并使用这些方法输出“ Hello world” 。

You can observe in the output that the print method is not providing a newline and two statements are printing together. Though, both the methods have the same functionality but still use them wisely.

您可以在输出中观察到print方法未提供换行符，并且两个语句一起打印。 尽管这两种方法都具有相同的功能，但是仍然明智地使用它们。
