Defined in header <istream>
template<     class CharT,     class Traits = std::char_traits<CharT> > class basic_istream : virtual public std::basic_ios<CharT, Traits>

类模板basic_istream提供了高层次的输入操作，对字符流的支持。支持的操作包括格式化输入（例如整数值或空格分隔的字符和字符串）和未格式化的输入（例如：原始字符和字符数组）。 basic_streambuf的基本类，访问通过basic_ios基类提供的接口实现此功能。在大多数实现中，是唯一的非继承的数据成员basic_istream，basic_istream::gcount()返回值.

Original:

The class template basic_istream provides support for high level input operations on character streams. The supported operations include formatted input (e.g. integer values or whitespace-separated characters and characters strings) and unformatted input (e.g. raw characters and character arrays). This functionality is implemented in terms of the interface provided by the underlying basic_streambuf class, accessed through the basic_ios base class. The only non-inherited data member of basic_istream, in most implementations, is the value returned by basic_istream::gcount().
