_stricmp返回错误的值,而字符串确实匹配.该怎么办

_stricmp returns wrong value while string DOES match. What to do?

本文关键字:怎么办 字符串 返回 stricmp 错误      更新时间:2023-10-16

我有这段代码:

                        second = strtok (NULL,"n");
                        logprintf(second);
                        if(_stricmp(second,"WINDOWS") == 0)

logprintf将数据打印到日志文件中,并打印"WINDOWS"(不带引号)。

但是_stricmp以某种方式返回13。。所以if检查永远不会通过。我试过用sscanf/sprintf/其他字符串方式,但都不起作用。我没主意了。

完整代码:

所有数据都已正确读取到"buf"中。

有人能建议如何解决那个问题吗?

看起来好像没有考虑CRLF行的结尾。以文本模式打开文件会将"\r\n"转换为"\n",但代码中没有这样做的内容。如果"WINDOWS"后面跟着"\r\n",则将其视为"WINDOWS\r"后面跟着一个"\n"。因为"\n"是您传递给strtok的全部信息。有几种可能的解决方案,但其中一种是将"\r\n"传递给strtok

13是回车符'r',因此您的输入有一个尾部'\r',打印时不会显示。要删除它,请将"rn"作为分隔符传递给strtok

13表示您的second字符串包含"WINDOWSr"r是一个回车字符-在Windows上,文本文件中的行以rn序列结束,因此您的getline()函数似乎终止于n,并将r作为字符串的一部分返回。
