Now that you've posted your code, is there a question you'd like to ask?

[vmanes]

Please use full words and full sentences to explain what your problem is.

We don't do your work for you - read the notices at the top of the forum.

When you post code, it's more readable (thus more likely to get a good response) if you use the code tags to ensure its format comes through - indentation helps. Like this:

That said, if you're reading the bits in main, why is the filestream passed to the converter? Pick one place to do the reading. If the size of the binary stream is not known, I'd go with the conversion function doing the reading, and adding the values up to make the decimal number as it reads in bits. Keep in mind that you'll be reading in the highest ordered bit first, and you don't know how high a power of 2 that is, do you? Or, are you sure to get formatted numbers (exactly 8 or 16 or 32 bits, for example)?
