new programmer needs some help

[Patrick Parks]

hi guys, i am trying to read in CD info from a file and put it into an
array, using a CD class. I have been working here for about 6-8 hours
trying to get the input file into an array. i just need some help
starting it. It needs to read 15 15 rows with 6 columns in each row.
Any help???

Don't mix non-standard I/O functions like getche() with standard C++ I/O,
that is guaranteed to drive you bonkers. In fact don't use non-standard I/O
at all.

Apart from that I don't see any real problems, what exactly is going wrong?
Even if you've made some attempts and they didn't work its a good idea to
post that code because

1) It show more clearly what you are trying to do than any description can.
2) It demonstrates what your level of skill is, and where there are gaps in
your knowledge
3) It proves you been trying for yourself (people don't like to do others
homework when they haven't made any effort).

It would also help to post a sample of the file you are trying to read.
