Dnight(Dnight),不知道。可能说法上的区别吧。以前还没有流这个概念。

“流”应该说是一个形象的比喻，比喻数据的传输就像水流一样流动，所以有“数据流”这个说法。输入\输出流，那就顾名思义啦：）

.........................
输出操作将一个对象转换为一个字符序列，输出到某一个地方；输入操作从某一个地方接受字符序列。输入输出操作可以看成是字符序列在源和目的之间的对象流动。所以叫流类
...........................
那字符序列又是什么,
流的输出和printf输出有什么区别呢

你可以把它想成是水！水流是由水分子组成，字符流是由字符组成！它们都可能从一个地方流到另一个地方！

其实就是输入输出操作，包括文件的读写

C++ 中的“流”就是指那些可以放在一串 operator << 最左边的东西

块表示可以对数据“随机操作”

流就是“顺序操作”

What A Stream Is
Like C, C++ does not have built-in input/output capability. All C++ compilers, however, come bundled with a systematic, object-oriented I/O package, known as the iostream classes. The “stream” is the central concept of the iostream classes. You can think of a stream object as a “smart file” that acts as a source and destination for bytes. A stream’s characteristics are determined by its class and by customized insertion and extraction operators.
Through device drivers, the disk operating system deals with the keyboard, screen, printer, and communication ports as extended files. The iostream classes interact with these extended files. Built-in classes support reading from and writing to memory with syntax identical to that for disk I/O, which makes it easy to derive stream classes.
