奇怪的 gcc 错误杂散/丢失终止” C语言中的字符
我收到以下错误：
error: missing terminating " character
并且
error: stray `\' in program
在这行 C 代码中：
system("sqlite3 -html /home/user/.rtcom-eventlogger/el.db \"SELECT service_id, event_type_id,free_text, remote_uid FROM Events WHERE remote_uid=\'%d\' ORDER BY start_time DESC;\" > lol.html", nr);
“nr”是一个整数变量。
我已经讨论过很多次了，但完全找不到解决方案。
编辑：如果我没有说清楚，错误是使用 gcc 编译时的输出。
I get the following errors:
error: missing terminating " character
and
error: stray `\' in program
In this line of C code:
system("sqlite3 -html /home/user/.rtcom-eventlogger/el.db \"SELECT service_id, event_type_id,free_text, remote_uid FROM Events WHERE remote_uid=\'%d\' ORDER BY start_time DESC;\" > lol.html", nr);
"nr" is a integer variable.
I have gone over this so many times but are totally stuck of finding a solution.
EDIT: The errors is the ouput while compiling with gcc if I didn't make that clear.

在 C 中的双引号字符串中，我认为
\'没有任何意义。看起来您的反斜杠是为了保护 shell 中的单引号，这意味着它们应该在字符串中使用双反斜杠：remote_uid=\\'%d\\'< /代码>。Within a double-quoted string in C, I don't think that
\'has any meaning. It looks like your backslashing there is meant to protect the single quotes in the shell, which means they should be double-backslashed within the string:remote_uid=\\'%d\\'.好吧，您不需要转义字符串内的单引号（例如
\'应该只是'），但我不确定这会导致你看到的错误。Well, you don't need to escape the single quotes inside the string (e.g.
\'should just be'), but I'm not sure that that would cause the error you're seeing.我遇到了同样的问题，试图做基本相同的事情。
我的问题是我使用 WinZip 来解压缩源代码。使用7z后效果很好。
I had the same problem, trying to do basically the same thing.
My problem was that I used WinZip to decompress the source. After using 7z it worked fine.
就我而言，我有一个带有转义“的外部定义变量，如下所示：
它被嵌入到如下代码中：
In my case I had an external define variable with escaped ", like this:
It was transcluded into code like this:
