ampersand

Y I'm not passing an x and I'm not passing a Y,& y I'm passing an ampersand x and ampersand y and can you take a guess as to what the ampersand operator must mean?

我不是传递X，也不是传递，我传递的是x和，你们可以猜一猜，这个符号是什么意思？

The query segment of the URI separates each argument by the ampersand (&) character, and each argument appears as a key-value pair separated by the equals (=) character.

URI的查询部分使用和号（&）来分隔每个参数，而每个参数都是以等号（=）分隔的键-值对出现的。

You may have noticed that when you placed the xclock job in the background, the message no longer said "Stopped" and that it was terminated with an ampersand (&).

您可能已经注意到，当您将xclock放在后台时，该消息不再显示“Stopped”，并且使用与符号（&）终止了它。
