I need some help with Binary I/O. I know how to do it when I am specifying the filename in the code
fstream fio("persons.txt", ios::in | ios::out | ios::binary | ios::trunc); What I need to know is how to open or create a file with a file name that will vary and wont be persons. txt everytime. Basically, a file name specified by the user. How would I do that? I can't seem to find anything online for it. Also, please dumb it down for me, I'm still kind of new to this.
