从文件中读取时的问题 [英] problem while Reading from file

问题描述

我已经在pro C中编写了一个程序，从文件中逐行读取（每行是字符串）

并在where条件下给出sql查询。我遇到的问题是，当我从文件中读取一行时，它还会读取一个新的行字符。所以，当我将此字符串提供给sql查询时，它显示此条件不存在任何记录。

Hi,
i have written a program in pro C to read line by line from file(each line is string)
and given to sql query in where condition. What the problem i have faced is when i read from file a line it also read a new line character.So when i give this string to sql query it displays no records exists for this condition.

还可以选择pincodefromfil到length - 1（消除\ n）然后进行比较!!

One more option could be you can substr the pincodefromfil till length - 1 (eliminate \n) and then do a comparison!!

另外一个选项可能是你可以将pincodefromfil直到length - 1（消除\ n）然后再比较!!

很好，我做到了。但它还没有工作。


这就是我做的
