How should I model the following design problem :

1) I need to read/write a set of bytes from/to the binary file between
a starting address and ending address.
2) Before writing the bytes I should pass file name with extension so
that the bytes will be written in that file.
3) I need to reduce the number of I/O operation while reading/writing
the bytes so that I could improve the performance.
4) How would I specify the error handling strategy?
5) What kind of design pattern I could employ to achieve the above
requirements.

If possible please point me to industrial strength c++ implementation

regards,
sri.

The purpose of these forums is not to do your classroom projects for
you. Use what you learned in the course to try to solve the problem; it
is part of the learning process.

Also, this is a pretty low level, tactical problem whose answers will
depend upon the specific language used, so you would be better off
trying a C++ forum. This forum usually deals with higher level design
issues.
