long path names for ifstream in(

[Gary Wessle]

hi
opening a file
ifstream in("../../../../../../data/ZB/Jun06/20060405");

then on the command line I do
fred@debian:~/myPrograms/cpp/practice/ticpp1/co2/3$ make; ./proj

is there a way to save some typing and cleaner than this.

thanks

Put the "../.." part in a std::string (or macro, yuck!) and prepend it
to all appropriate file names? Use the absolute path? Put a link to the
data directory in your executable directory? Require that the user run
the executable from a certain location so you can use relative paths?
Etc. etc. etc.
