This is the behavior mandated by the standard: the default openmode for an fstream is "in | out", which is the same as "r+" in C. You can change it, use for example "out", or use an ofstream. Here and elsewhere, since we are talking about free software, I suggest having a look to the source code for fstream, there are rather extensive comments...Hi, when I try to connect a non existent file to an fstream object calling the open member function, the file is not created.
