这句话是以读的方式打开一个名为***.in的文件,并且把里面的内容作为标准输入。也就是说,我们平时用scanf的时候,是要求用户从键盘输入数据,而加了这句话以后,输入数据这一步就变成程序自动去读取文件的数据作为输入,免去了我们手工输入这一步。这样我们调试的时候可以把数据写入文件然后让程序去读取,大大简化了调试...
I'm trying to make a ruleeval "file_path"to load tokens from a file and evaluate them. Initially I haveyyin = stdin(I use the functionsetStandardInput()to do this). When a user introduceseval "file_path"the parser swapsyyinfromstdinto the file pointer (with the functionsetFileInput()...
int fflush(FILE *stream); If stream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is...

These pointers are constants, and can't be assigned new values. The freopen function can be used to redirect the streams to disk files or to other devices. The operating system allows you to redirect a program's standard input and output at the command level....
上面的代码仅接受单个输入,并为第二个输入提供相同的结果。原因是因为该字符串已经存储在缓冲区中,即流尚未清除,因为它期望带有空格或换行的字符串。因此,为了处理这种情况,使用了fflush(stdin)。 // C program to illustrate flush(stdin) // This program works as expected only // in certain compilers like...
Python文件"<stdin>",line 1, in <module> 的解释 概述 在Python开发中,经常会遇到一些错误信息,其中一个常见的错误是"File “<stdin>”, line 1, in <module>"。这个错误信息通常出现在交互式解释器(REPL)中,当我们尝试运行一段代码时出现问题。在本文中,我将向你介绍这个错误的原因,并解释如何解决它。

yes, stdin is a concept that exists in various programming languages, not just c. many programming languages provide built-in mechanisms or libraries to read input from the standard input stream. for example, in python, you can use the input() function to read user input from stdin. ...
