reading complex data file

I'm new to C++ programming, and I would like to learn how to read a binary file that, when translated, contains a HEADER segment, a primary TEXT segment (ASCII containing keywords) , a DATA (base 10) segment, and an ANALYSIS segment. In other words, I would like help with a code that allows me to read one of these relatively large files, and spit out both TEXT and numerical values into an interpretable format in a fashion that is as quick as possible. Can anyone help?

Look for stream iterator.

How are the segments delimited in the binary file?
