I. Io and stream
Data input and output (I/O for input/output)The input and output of standard input devices and standard output devices are referred to as standard I/OThe input and output of files stored on an external disk are referred to as files I/O.The input and output of the specified string bucket in the memory are referred to as string I/O.
The process of data input and output can be visually viewed as a stream.The operation for retrieving data from a stream is called an "extract" (input

Operators

"Boost/operators. HPP"
The operators library consists of multiple base classes. Each class generates Operators related to its name concept. You can use them in inheritance mode. If you need more than one function, you need to use multiple inheritance. Fortunately, operators defines some composite concepts. In most cases, multi-inheritance is not required. The following describes some of the most common operator classes, includin
Personal Understanding:1) Formation: program--flow--a structure of other equipment. Other devices can refer to: programs, files, external devices and everything else.2) input stream: from stream to program. Another understanding: Other devices to the stream. Individuals tend to use the former. Output is similar.3) The basic stream is: basic stream (iostream), file Stream (Iofstream), character stream (Iostringstream). Use Baidu or Google specifically.Some details:1) out mode (ofstream:out) opens
