Hi, I wonder, what is the meaning of this command: ''\\''

推荐答案

这不是命令.
它是一个字符(因此带有单引号字符)，它是一个反斜杠字符.
在字符串和字符文字中，为了输入无法键入或可能引起混淆的特殊字符，您可以使用特殊字符作为序列介绍器(反斜杠字符)，并提示编译器将下一个字符用作特殊的
字符，而不是按原样解释.

例如，如果要在字符文字中输入单引号字符，那么''''的含义并不那么明显:因此您输入它
作为

It isn''t a command.
It is a single character (hence the single quote characters) which is a single backslash character.
In strings and character literals, in order to enter special characters which can''t be typed or which might be confusing, you use a special character as a sequence introducer - the backslash character, and that telkls the compiler to take teh next character as a special
character rather than interpret it as is.

For example, if you want to enter a single quote character in a character literal, it is not that obvious what '''''' means: so you enter it
as

'\''

'   Start of character lieteral
\   Start of special character sequence
'   Insert a single quote character
'   End of character literal

要插入反斜杠字符，请在其前面加上另一个反斜杠字符作为序列介绍器.

常见序列包括:

To insert a backslash character, you prefix it with another backslash character as the sequence introducer.

Common sequences include:

\\   Back slash
\'   Single quote
\"   Double quote
\n   Newline
\r   Return
\t   Tab

我不符合您的要求，但"//"是C和笑脸语言中的转义字符.
