从文本文件一次读取一个单词 [英] Reading one word at a time from text file

问题描述

我如何一次从一个文本文件中读取一个单词，该单词之间用空格隔开.指针也应随之移动.我的意思是我不想在阅读一行后使用String.split方法.我想阅读单词并将单词插入文件中的特定位置.

How do i read one word at a time from a text file in which the words are separated by a white space. The pointer should also move along. I mean i dont want to use the String.split method after reading a line. I want to read words and insert a word at a particular position in the file. Is there a simple way to do this??

推荐答案

StreamReader具有一次每次读取一个字符的Read()方法.使用(缓冲版本 [

StreamReader has a Read() method that reads one character at a time. It might be more efficient to use the (buffered version[^]) at the cost of getting a few extra characters and more complexity but getting one char at a time is slow.

All you then need do is loop, checking each each char in turn.

只需逐行读取并使用
将其标记在空间上 < pre lang ="c ++"> arr = strtok(buffer，'''');</pre>

从Internet检查正确的语法.
arr将带有单词.

Hi,
Just read line by line and token it on space using
<pre lang="c++">arr = strtok(buffer,'' '');</pre>

check the correct syntax from internet.
arr will have the words.
