C++ 通过以下几个类支持文件的输入输出： ofstream: 写操作（输出）的文件类 (由ostream引申而来) ifst...
When reading from std::ifstream and the input ends, it doesn’t seem possible to differentiate between eof & read error. Attaching code that demonstrates the problem (forces a read error with the help of LockFileEx API). ifstream_issue.cpp I would expect that the latter case h...
