how do i specify a place to save/read a file? the book i am using for class is written with windows compilers/filesystems in mind and i have looked at the documentation in xcode and cannot figure out what i need to do to change where the file is saved to or read from. the example from the textbook (the part i am having problems with) is:
Code:
ifstream in("a:Name.txt");
in.getline(name, 15);
where the previous example created Name.txt and in the current file, name is declared as char name[15] previously. i have changed the code to match the location on my local machine, but nothing is read in. do i need to include something other than iostream.h and fstream.h?
i can compile, build, and run but my run log window shows me nothing other than "session started at . . ."
thanks!

Specifying a POSIX file path should work. Are you sure that everything is where you think it is?

how would i do that? and yeah, the file name is correct. i have tried specifying by the drive name and also just the file name. should i specify full path name, beginning from root?

You should specify the name just as if you were typing it into the shell (except without any shell shortcuts like $HOME, of course). If you are in the directory with the file, just the file name will work. Absolute paths will work no matter where you are. For instance, replacing "a:Name.txt" with "/Users/chuck/Name.txt" will open the file if it's in my home folder.

ok, thank you. will that work for removable drives as well? (ie /volumes/driveName/folder\ Name/fileName.ext)
