wow, i'm not a C++ beginner and can't understand what you are trying to
do.
Let me try to:
You have a file in a specific format, and you want to read the
information from the file, parse according to the format, and than
store the information on the memory so you can use it in your program?
If that is thet case, you should read the file line by line using some
io functions, and than parse the string you have in your hand. that you
can do using scanf the its siblings.
Then you should figure the best way to represent the information. That
depends in what do you wanna do with it afterwards. So if you can,
please elaborate on the matter.
