如何在 C++ 中逐个字符地从文本文件中读取 [英] How to Read from a Text File, Character by Character in C++

问题描述

我想知道是否有人可以帮助我弄清楚如何从 C++ 中的文本文件中逐个字符地读取.这样，我可以有一个 while 循环(虽然仍有文本)，我将文本文档中的下一个字符存储在临时变量中，以便我可以对它做一些事情，然后对下一个字符重复该过程.我知道如何打开文件和所有内容，但 temp = textFile.getchar() 似乎不起作用.提前致谢.

I was wondering if someone could help me figure out how to read from a text file in C++, character by character. That way, I could have a while loop (while there's still text left) where I store the next character in the text document in a temp variable so I could do something with it, then repeat the process with the next character. I know how to open the file and everything, but temp = textFile.getchar() doesn't seem to work. Thanks in advance.

推荐答案

您可以尝试以下操作:

char ch;
fstream fin("file", fstream::in);
while (fin >> noskipws >> ch) {
    cout << ch; // Or whatever
}
