由于某种原因,此排序代码无法正常工作:

std::fstream theFile;
theFile.open(<someFilename>, std::ios::beg |std::ios::out|std::ios::binary|std::ios::trunc);
theFile << 1;          //1 is being written as a string
int var= 25;

theFile << 25;        //same thing, 25 is written as a string

可能是什么问题呢？我正在使用Visual Studio 2010附带的Microsoft C++编译器.
