<iostream>

<iostream>是C++中一个重要的头文件，定义了标准输入/输出流对象。它包含了<iosteam>、<ios>、<streambuf>、<istream>、<ostream>和<iosfwd>这些头文件。该头文件提供了输入和输出的流类和函数，可以实现程序与控制台或文件之间的交互操作。对于使用C++进行输入输出操作，掌握<iostream>库的知识至关重要。其中，istream和ostream是iostream库的基础，分别表示输入流和输出流。流是指要从某种IO设备上读出或写入的字符序列。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
