I was making a C++ calculator program that removes unrecognized text from the argument array, and I just so happened to enter d^ when I was running the program. 我正在制作一个C ++计算器程序，它从参数数组中删除无法识别的文本，而我正好在运行程序时输入d ^。 The Windows command prompt then showed "More? ", and I couldn't figure out why, since I didn't script this. 然后Windows命令提示符显示“更多？”，我无法找出原因，因为我没有编写脚本。 I realized it was coming up since I wrote d^, but why does it do this? 我意识到自从我写了d ^之后就会出现，但为什么会这样呢？ What does "More? " do? “更多？”有什么作用？

More? "does" nothing. “什么也没做。 It asks you to continue your command. 它要求你继续你的命令。

^ is an "escape character" that tells the Interpreter to treat the following character different. ^是一个“转义字符”，告诉解释器将以下字符区别对待。 The following character is a Line End ("Enter") - ^ tells the Interpreter not to handle it as end of line ("Enter"), so it asks you to continue. 以下字符是行结束（“Enter”） - ^告诉解释器不要将其作为行尾（“Enter”）处理，因此它会要求您继续。
