special character

基本解释

Usually this is upper case, lower case, special character and a number.
通常是大写字母、小写字母、特殊字符和数字。
It also works with any character number, so you can use a special character as a marker.
它还可以使用任何字符数字，所以您可以将特殊字符用作标志。
A percent sign (%) is translated to a newline, so if you want a % or any other special character, precede it with a backslash (\).
百分号（%）将转换为空行，所以如果要使用 % 或其他任何特殊字符，就要在前面加上反斜线（\）。

0 And we'll also see backslash 0 which is actually the special character that's used at the end of a string to say no more string after this point in memory.
还有0,用于存储器中字符串末尾,表示在此之后就,没有字符了。
