WebYour code does not work, because: The line std::cout << infile; is wrong. If you want to print the result of istream::operator bool() in order to determine whether the file was successfully opened, then you should write std::cout << infile.operator bool(); or std::cout << static_cast(infile); instead. However, it would probably be better to simply write … Web类 istrstream 实现基于数组的流上的输入操作。 它实际上将原生数组 I/O 设备( std:: strstreambuf )包装进 std::basic_istream 的高层接口。 istrstream 的典型实现仅保有一个非导出的数据成员: std:: strstreambuf 类型对象。. 注意. istrstream 从 C++98 起被弃用, std::istringstream 和 boost::iostreams::array_source 是受推荐的 ...
