％dn是格式字符串吗? [英] Is %dn a format string?

问题描述

我最近在代码中碰到了这一行-

I recently came across this line in a code -

fprintf(logfile,"   |-IP Version        : %dn",(unsigned int)iph->version);

这里的％dn"是格式字符串吗?如果是这样，那意味着什么?

Is "%dn" here a format string ? If so , what does it signify ?

推荐答案

听起来好像有人想写%d\n以换行符终止行，但是反斜线在某处丢失了.格式代码无论如何都以"d"结尾.

It sounds a bit like someone wanted to write %d\n to terminate the line with a linefeed, but the backslash got lost somewhere. The format code, in any case, ends with the "d".
