If you want to see the binary value of each byte then you will have to convert the bytes yourself because neither c nor c++ has build-in functions to do that (unfortunately). Here is an example program how to do that. You will probably want to leave the vector as an int vector and convert the data only for display purposes.

Thanks Ancient Dragon. I got some advice on how to display the decimal representation.
Turns out the binary is being stored but when I display, it is displaying the encoded version of it. (ascii for text and whatever that is for the jpg).
That is what was confusing me. I thought if I used the binary flag, it would show me the binary.
Now I just need to make an algorithm that encrypts and decrypts the stored data right?
BTW can you tell me what type of encoding is being used for the jpg?

Google for "jpg file format" and it will tell you the file format.

Yes, just like the link I posted, but do that algorithm for every byte.
