带有eof（）函数的文件结尾 [英] end of file with eof() function

问题描述

喜。我正在使用eof（）函数，但似乎它不起作用。我写了

fstream f（test.txt）;

while（！f.eof（））

cout<< 1;

并且在我的文件中我写了sara

但程序没有完成并进入无限循环。为什么？

请帮帮我

谢谢

推荐答案

但程序没有完成并进入无限循环。为什么？

but the program doesn't finish and enters in the infinite loop . why?

因为你没有从文件中读取。

Because you are not reading from the file.

正如CPallini所解释的那样，你没有读取文件。使用下面的示例代码进行阅读

As explained by CPallini you are not reading the file. Use below sample code for reading

fstream f( "test.txt", ios::in );
    while( !inf.eof() ) {
        cout << f.get() << "\n";
    }
