error, missing terminating character
提问by monkey doodle
I have this missing terminating character, but I'm not sure what it wants or needs. I believe it's inside its inside the while second while loop. what can be done to fix this. I'm trying to input a text file with a string of paths. And then from there I parse through this string and put it to a link list. and then create a search function afterwards.
我有这个缺少的终止字符，但我不确定它想要或需要什么。我相信它在 while 第二个 while 循环中。可以做些什么来解决这个问题。我正在尝试输入一个带有路径字符串的文本文件。然后从那里我解析这个字符串并将其放入链接列表。然后创建一个搜索功能。
text file: path.txt
文本文件：path.txt
a/a1.txt
a/a2.txt
a/b/b3.txt
a/b/b4.txt
a/c/c4.txt
a/c/c5.txt
a/c/d/d6.txt
a/c/d/g

In the line
在行
char *token = strtok(inputstr, "\");
you need to use "\\"to specify a single backslash character.
您需要使用"\\"来指定单个反斜杠字符。
A single backslash is treated as the start of a multi-character escape sequence.
单个反斜杠被视为多字符转义序列的开始。
