无法重置和移动指针 [英] unable to reset and move the pointer

问题描述

我在重置时遇到问题，无法使用c ++中的seekg（）函数移动文本文件中的指针。该怎么办？

i have a problem in resetting and unable to move the pointer in the text file using seekg()function in c++. what to do ??

推荐答案

你检查seekg返回的内容以及文件中是否包含那么多字节...



raghu

R u checking what the seekg is returning and whether the file is having that much bytes in it...

当我将其重置为起始点时由

file.seekg（0，ios :: beg）;

之后通过file.tellg（）显示这个数字4294967295

所以它没有重新安置，我不知道该怎么办。我的最大文件大小是65751180。

when i reset it to starting point by
file.seekg(0,ios::beg);
after this through file.tellg() it shows this number 4294967295
so it has not resetted, i don''t know what to do. my max file size is 65751180.

通常它的行为就像那样。

我尝试了一小段代码并打印了值正确的。

你能否发布一些关于你如何进行搜寻和告诉的代码？

Usually it dosent behave that way.
I tried a small piece of code and it printed the value properly.
Can you post the piece of code on how u are doing the seek and tell?
